The Sigma 70-200 is an amazing lens, but just how amazing?
Just recently I read a lens review where the person writing the review said, “Sharpness is not something I normally notice on a lens.” To this point all I can say is, wait, what?
How can any photographer, specifically one who is writing a review of a lens, not notice how sharp a lens is? Maybe I’m wrong, but when shopping for a new lens, isn’t the sharpness of a lens just as important as it’s focal length?
For this review, I am talking specifically about the sharpness. Even more specifically, the sharpness at it’s widest aperture setting of f/2.8. I am also testing it’s sharpness with OS (optical stabilization) both on and off.
First, let’s take a look at a real world application for a lens like the 70-200 — A wedding. Weddings are a great test bed because you need a lens that can give you a sharp, great looking image in conditions you often can’t plan for. A common rule when shooting with a telephoto lens is to have your shutter speed match, if not exceed the focal length of your lens. So, if shooting at 200mm, you’d ideally have a shutter speed around 1/250. A rule like this is easy to follow if you can plan for the situation you’re shooting in, but when working a fast paced job, like a wedding, you may not always be able to comply with a rule like this. That’s why a lens with optical stabilization (also known as IS, or VC) can be so important.
Here are two sample images illustrating the sharpness of the Sigma 70-200 with OS on. This first sample is an uncropped photo, straight from the camera. Even at this size, not zoomed in, it’s apparent how clean the details are. It’s even more amazing when you consider this image was shot at 1/80th of a second, zoomed in at 200mm. That’s way below the threshold for steady, clean shooting. Shooting a lens at this speed, at this focal length would normally mean your photos would suffer from a bad case of the jitters.
Now let’s zoom in and look at some detail from this photo with stabilization turned on. You can easily see just how amazing this lens is. The details, like the lines around the eyes, and the eyelashes, are damn near perfectly sharp. And don’t forget, this is wide open at f/2.8. Historically a lens’ widest aperture setting is not where it performs at its best in terms of sharpness, but here we can see the Sigma performing astonishingly well.
So, we’ve shown that the Sigma’s sharpness with OS enabled is amazing, but does that mean it’ll function equally well when you have enough light to shoot without OS? Let’s find out!
In this first image, we can see that our subject (the bird) is acceptably sharp at f/2.8. For reference, the focus point was placed over the bird’s eye, just as it was for our subject in the wedding photo above.
Here I’ve cropped the image in the way I would do it if I were sharing this photo on social media, or a photo-sharing site.
This may not be an extreme crop, but even at this modest size we can see the details are being maintained in stunning fashion.
This is an extreme crop. In fact, I am zooming in around 25% further than the photo’s max native resolution.
It’s here, at this extreme zoom, that we see just how awesome the Sigma’s sharpness really is. The fidelity of the Sigma 70-200mm lens means you can scale your photos a bit beyond 100% and still retain respectable sharpness. In practical terms, this means higher quality prints at larger sizes, and the ability to really dig into your photos to create a better composition in post.
One last thought on image quality concerns color fringing. I’ve read elsewhere that Canon lenses tend to fringe with a magenta tint, and Sigmas tend to fringe with a greenish tint. That green fringe is evident here. I can also say through experience that the amount of color fringing on the Sigma is less than it is on my Canon lenses. This only applies to the Canon lenses I own, and the amount of difference in fringing varies from lens to lens.
So, here’s where I, the reviewer, try to summarize my thoughts on the subject. Before I do that, however, let me just address one argument that many photographers have made since the beginning of time. That is, simply, that you should never waste money on a non-brand lens.
When I first used this lens 2 weeks ago, it only took a few hours before someone said, “That’s not a Canon lens, but hey, it’s cheaper, right?”
“Cheaper, and perhaps better.”, I replied. The guy who made the comment looked shocked. I’m sure he either felt I was a first year newb photographer, or that I was just crazy. But, when I turned the camera around and showed him some of the photos I was taking he simply nodded, shut his mouth and sat down in his chair. Why? Because the proof is in the pudding; you can’t dispute results.
I’ve owned a 70-200 Canon lens for over 6 years and I’ve loved it every time I’ve used it. The cold, hard truth however, is that this Sigma is better. Oh yea, it’s cheaper too.
In my search for great, cheap gear, this is one is a must-have
Modifiers let photographers take their light and mess around, get creative. Small modifiers can give you a sharp, zappy light with strong contrast. Large modifiers can even out shadows, spilling light across a surface. Huge modifiers do the same, only they take that principle to the extreme! At 7 feet, this Westcott umbrella is about as big as you can get while still being manageable in the field.
Because it’s an umbrella, albeit a very large one, it folds up quickly and easily into a relatively small volume. That means you can throw it into the back of your small car, or take it with you into the field without having to deal with something more cumbersome like a metal framed light panel. Like most studio umbrellas, nearly all studio light or speedlite brackets will accommodate it nicely.
One thing that really surprised me with the Westcott is how well it works with a single speedlite. You’d expect something 7 feet across to eat up the light from a tiny flash unit, but that’s not the case. A single 430ex II speedlite is more than capable of working with this gigantic modifier with great results. I’d suggest using at least two speedlites to help preserve battery life, but in a pinch 1 speedlite will work flawlessly.
I used this light this past weekend while photographing my step-daughter’s wedding. I only had 5 minutes to get the shot and that included light step up, composition, and posing. Because I only had one light I used a technique where you take several photos of the scene, moving the light around between each shutter release. Once you’re done you stitch the photos together, creating a photo that looks as though it was light with 4 or more giant modifiers.
Below is the final photo, beautifully lit thanks to the Westcott 7′ White Umbrella
the Sigma 70-200mm f/2.8 from lensrentals has arrived. Here are some sample images
I was very excited to have this lens arrive. I am renting it specifically for a job I have coming up over the next week that requires a lot of hand-held photography and the Optical Stabilization offered by the Sigma is the chief reason why I choose to rent this particular lens.
Image Quality was also important and all of the reviews I read online indicated that this lens would be a great choice. Below are a few sample images I took with the Sigma while walking through the yard. All photos were taken with the aperture wide open at f/2.8.

The weather forecast was calling for 3-6 inches of snow, the temp hovering around 33 degrees. If you’ve ever lived on the east coast, then you know it can snow even when the temp is above freezing and this can cause you a few problems.
How to Survive Bad Weather as a Photographer
Whether it’s 36 degrees Fahrenheit , or -10 below, the problems dealing with the cold are pretty much the same; staying warm is your first-most priority. The second priority is staying dry if possible. Anything below 20 degrees and this is relatively easy. The colder the air temperature, the less likelihood the snow will melt upon landing on you and your equipment.
But when temperatures get above 20, especially above 32 degrees, snow can melt on contact and ultimately effect your clothes and equipment in the same way as if you were standing in a rain storm. For the event, we would be standing on the ice, over a frozen lake, right in the middle of the action and subsequently, the weather. I took this into account and set up several shoot-through umbrellas attached to light stands to act as actual umbrellas, keeping the snow off of my speedlites and giving me a dry place to stand. When I had to change location to get a better vantage point for a photo, I would take my photo and then retreat under the umbrella and dab-dry my camera with a soft towel. This meant my camera gear was never in any real danger from water damage.
Another issue with shooting in a blizzard is visibility. I had brought my speedlites so I could stop the action in midair, just as these poor folks were about to take the plunge, as well as to help equalize the exposure between the subject and the near-pure white background. Problem is, when the snow is coming down heavily and you shoot with a flash, all you’ll see is the reflected light bouncing off the snow in the air, ultimately overexposing your photo. Because of this I had to work in two modes. One mode was in shutter priority with no flash. I never use shutter priority, like never ever. But here, where I need around 1/600 of a second to get a crisp action shot, using Shutter Priority was the best bet. For this scenario I also had my ISO bumped up to 800 and my aperture around f/11 (+/- a few stops depending on the changing light).
When the snow would let up a little, I would turn back to using my speedlites. I was using multiple speedlites to help spread the load so as not to overtax the batteries. The lights were TTL, unmodified, zoomed out to their max. When using the lights my camera was set at 1/200 of a second, around f/8 and an ISO of 100. 1/200 of a second works here because the flash is stopping the action, rather than raw shutter speed. You could also have used Highspeed Sync in this case, but the burden on your flashes would mean long recycle times and possible missed photo opportunities due to that recycle time.
The was coming down so thick at times it was hard to even stop and look at my LCD screen to see how we were doing with the photos. The snow and water made everything on the back of the LCD blurry and I just had to trust in my own knowledge and the TTL system.
I was very happy to see that the 5D Mark III’s auto focus system handled the heavy snow amazingly well. There were a few hiccups where it would focus on an area of falling snow, rather than the intended subject, but for the most part it cut through the white stuff and found the target nearly all of the time.
We spent 4 hours on the ice, in the driving snow, in the freezing cold and, to be honest, I started to envy the jumpers who only had to spend 10 seconds in the 33 degree water before being whisked off to a heated tent. But the experience was fantastic. I actually like being in the snow, and there, in the middle of this expansive frozen lake, I found the setting very beautiful.
It should be mentioned that it was because of my great friends at the Akron-Canton Regional Food Bank that I got the opportunity to come and take photos of this thrilling (chilling?) event. I strongly ask you to support ACRBD and other Food Banks by donating food, time, and money. It’s a great cause!

Sometimes you just hope the stars align. It can be the talent; are they willing to go along with this crazy idea of mine? Sometimes it’s making the client understand the intricacies of the shot. Sometimes it’s something that’s completely out of your control like the weather.
Dealing with, and planning for weather as a photographer
Weather is the bane of all photographers. At best you can rely on the weather channel to give you the conditions that may exist in, oh, say 2 hours from now. For fairly small time frames, weather predictions are usually in the ball-park of what the reality will be. But, say the shoot is 5 days away, a week, 10 days or more! Well, then you’re stepping into some really iffy territory. Sure, you can probably be guaranteed that it’s not going to snow in the middle of July, but trying to predict puffy clouds against a clear sky at sunset a week from today? Yeah, not gonna happen – most likely. If you’re lucky everything will work out, and if you’re not, you are in for total re-think of how you have to approach your photo.
I’m not trying to get a pretty good photo, I am trying to get THE photo, the one that is in my head. During rainy seasons we’ll often set a primary day and then a back up day just in case the weather is not cooperating at all. This is sort of ‘best-case’ planning for avoiding ‘worst-case’ scenarios. Even then, if your back-up date approaches and the weather still isn’t in your corner, you have to be ready to prepared to make the best of what you’ve been given. Thankfully, bad weather doesn’t mean bad photos. As Moose Peterson says, some of the best photos are made in the worst weather. Even then, however, it’s not a good idea to drag your model into a tornado and just hope she keeps her face to the light as she’s being lifted into the air, on her way to meet the Great and Powerful Oz.
There are also times when a certain type of weather is a necessity in your photo. Your rain jacket product shoot might require a backdrop of storm clouds, or that magazine shoot you’re on depends on a sunny beach while you’re taking photos of surfers. In these cases you have 3 options.
- Take your photo in whatever weather you’re given and then make any needed changes in post.
- Head into the studio and just make the weather you need
- Pay a shaman to keep the bad-weather demons at bay
You wouldn’t be the first photographer who’s had to resort to any of the above options. Personally, in a pinch, I would opt for the studio option if all else fails. But, in my opinion, there’s no substitute for the real thing.
All of this came into play recently when I had a shoot scheduled, several weeks in advance, that called for snow. I wanted the whole sha-bang. Snow on the ground and snow falling from the sky. Why was falling snow important? Well, it would be nice to capture snow falling throughout the image, but more important, nothing beats the look of freshly fallen snow on the ground. So, with my desire for fresh snow firmly in place, so began the anxiety laced waiting game. You know the game, the one where you’re checking weather.com 5 times a day to see if your dreams will come true?
Luck was on my side. As the day approached the likely hood of snow kept increasing. On the day of the shoot snow was forecast to start falling at 4pm, exactly 1 hour before the scheduled shoot – Perfect! We packed up the gear and headed out. Our location was an area next to the Cuyahoga river, deep inside of the Cuyahoga Valley National Park. Less than 15 minutes from our arrival the snow began to fall, heavily. So heavily in fact we lost control of our car for a moment as it struggled to deal with the inch of fresh snow covering the small, windy road. We made it off of the road and into the parking lot without further issues.
There was a new problem however. Remember all that snow I wished for? Well, there was so much snow falling that it caused a white out. Visibility was no more than just 20 feet or so – not so good for a photo that required a river-scape in the background. Hedging our bets we walked down the trails to our final location and began to set up our gear.
In any situation where you’re dealing with wet conditions (snow is, after all, just water) it’s important to take the safety of your gear into consideration. We took extra shoot-through umbrellas and used them as, well, umbrellas, shielding our flashes from the heavy snow. My cameras, a 5d mark II and mark III, are both weather proofed so as long as I took some simple precautions to keep them from being heavily soaked they would be fine.
By the time we finished our set up, the falling snow had slowed down to a workable level. We got the talent in place and started to snap away. Right away, we knew everything was working beautifully. The snow, the light, the location, the river – all of it was playing together just as I had seen it in my head for all of these weeks. It felt so great to have everything come together at the last moment and, pun alert, just click.
Not all shoots will work out this well. The weather is something you can’t predict with any degree of certainty, at least not 100%, so you have to plan ahead – sometimes weeks ahead. Be prepared to be flexible, and make sure your client understands they may need to be flexible too. If it’s a large budget shoot with a lot riding on the final frame, it’s worth taking the time to get it done right in the right conditions.

Winter is coming to a close – cold mornings bring snow, all to be washed away by after noon rain, and then draped in snow once again as the sun sets. This transition from winter to spring is often marked by potholed streets edged with slopes of dirty snow, but you can still find some winter-chilled character in landscapes and the people who are interacting with it.
A lot of effort goes into lighting your shots. Controlling the pattern of light is always important, but corralling color temperature and light source also fall high on that list of priorities. Mixing continuous light and strobe is easy enough, but not always desired. A flashes ability to choke out ambient light is one of the strengths of strobe photography – especially when the objective is to freeze motion. There are creative techniques, however, that meld both strobe and continuous light to achieve a mix of motion and stillness.
This application of showing motion can be used for all types of photos. Most often you’ll see this technique in sports photography – it’s always nice to show an athlete in motion, applying their craft. But there are many, non-sports related, uses for mixing flash and continuous light sources. You can use it to imply movement, giving your photo an almost ghostly quality. As the subject moves through your frame, they’ll leave an ethereal trail behind them, this trail is caused by the continuous lighting. At the end of their move they should be frozen in place by the strobe, giving them sharp definition.
The technique uses at least 2 lights (one continuous and one strobe as we’ve mentioned) but you can employ as many lights of each type as needed. Apart from the lighting, there’s some working you need to do behind the camera as well. The first change is fairly obvious – Your shutter speed has to be long enough to allow for capturing motion. Speeds of 1/250 or more are usually required to stop motion, so naturally turning the dial the other way will increase your chances of capturing the movement of your subject. You’ll need to play around with your shutter speed to see what works best for your scenario, but generally speaking a speed of 1/30 is a great place to start, and then dial up or down as needed.
The second piece of work you need to do happens behind the camera. You must switch your camera’s flash sync from 1st, to 2nd curtain (also known as rear curtain). What this does is fire your flash at the end of the exposure, where-as normal flash operation will trigger the flash at the start of an exposure. The reason for this change is aesthetic. 1st curtain flash will make your subject sharp at the start of your exposure, and any motion that happens after the flash will then be captured by the rest of the exposure. The end result is a sharp subject with motion blur moving forwards from the subject. Now, if you’re a fan of cartoons (which I am!) then you’ll know that motion blur should always move away from the subject, leaving a trail of where they have been. 2nd curtain flash does exactly this. With 2nd curtain enabled, the first part of your exposure captures the motion and then, right before the shutter closes, the flash fires, capturing the subject sharply in their end position, leaving a trail of where they’ve been behind them.
Both Canon and Nikon support 2nd curtain flash. To enable this you have to attach a canon (or Nikon if that’s your system) brand flash to your camera. From there you can either set 2nd curtain from your camera menu, or the flash menu – check your manuals because each model of flash and camera does it slightly differently.
There! Now you have 2nd curtain enabled on your on-camera flash! Oh, but wait, there’s a problem. Shooting flash from the camera is OK in a pinch, but for flattering light we know we have to get the flash off the camera. Okay, there we go, now that flash is on a stand and in a better position. But wait, now how to we get 2nd curtain to work? As soon as you take your flash off the camera it stops accepting 2nd curtain as a flash option. How do we work around this?
Well, there are several methods. If you’re using only two lights, one continuous, one strobe, then you can use a sync cable to stretch from your camera to the flash. This will restore communication between your camera and the flash and allow the flash to operate in 2nd curtain. Now, if you’re using several TTL enabled flashes wirelessly you might expect that you could set 2nd curtain operation on your master flash and then use that to communicate to your slave flashes. Sadly, this is not a reality. Canon has stated that 2nd curtain via master/slave communication is not possible, and therefore you can not use this method with an array of wireless speedlites. Bummer!
So, what if you need more than one light, or maybe you need a power output beefier than what your speedlite can produce. Well, I found a work around! Most studio strobes have an optical sensor that will fire the flash the moment it senses a flash from another strobe. So, what I’ve done is take my canon speedlite, using it as an on-camera flash I’ve set it to fire as 2nd curtain and then I bottom out it’s power to 1/128th power. At this power it’s not contributing light to my scene at all. Instead, all it’s doing is triggering my studio strobe at the end of the exposure.
There are other, more expensive options at your disposal too. Pocketwizards, and other transmitters, have their own options for allowing 2nd curtain functionality wirelessly. But, for the most part, the optical slave option works in most situations without any drawbacks.
Below is an example of 2nd curtain flash. For this example I am using a sync cable from camera to flash since I am only using two lights and I’m standing only feet from the subject. My direction to the subject was for her to turn her head as I pressed the shutter button with the anticipation that she’ll finish turning her head by the time the shutters closes and the flash fires. It will require a few takes to get the motion and timing right, but once you reach a working rhythm the photos will start coming in Fast and Furious™.
Another example of motion blur using the same technique. Here I asked the subject to look at the continuous light source for a 1 second before turning 180º and changing his pose. The flash fires at the end of the exposure to capture him in detail as he begins to play the sax while leaving a motion trail from his original position.

Modern DSLRs are amazing devices. Not long after the 5D Mark II introduced the ability to shoot high quality video, the film world took notice and started to use it as an essential piece of equipment in movie making. Not only are DSLRs small, and therefore easy to work with, they are also relatively cheap, and you get the picture quality afforded to you from using your DSLR lenses.
Long before I started taking pictures as a professional photographer, I was (and still am) a graphic designer. One of the many hats I get to wear when I am working for my design clients is that of a creative director. At times this means I am on set, working with a film crew, to make sure the design vision translates seamlessly to video.
I’ve gotten a lot of valuable experience behind the motion picture lens from my time on these types of projects. This has in turn given me a great perspective on how to use my DLSR’s video mode. And now, with everything digitally integrated between a myriad of programs, there’s not much you can’t do with the video you take with your DSLR.
Over the holidays we worked on a little project that called for some video, lighting, visual effects and compositing. I love these types of jobs because they are a great way to extend your artistic vision into several mediums. Below are a couple of stills showing the before and after of the raw footage and final, composited video.
Here is a small, 3 second clip.

Early in November I had the opportunity to photograph a wedding for an absolutely wonderful couple; Jim & Leslie. We met Leslie through a previous job, The Akron-Canton Regional Foodbank, where she works in the fundraising department. When we first met to discuss if we would be a good fit for her wedding, (We met in mid summer, several months before her wedding date), she expressed how important it was that the wedding photos shouldn’t staged – she wanted a very sweet, intimate, editorial look to her photos — it just so happens that shooting in an editorial fashion is one of my favorite styles for weddings
When someone says, “Editorial”, it can mean several different things. For the most part, editorial means any photo that happens naturally in the moment without the photographer staging or intervening in the photo in anyway. When I am shooting a wedding I’d suspect that nearly 95% of of my photos are shot in an editorial manner. The last 5% are things like formals where the photographer needs to work hand in hand with the bridal party and family in order to get all of the expected photos.
Before any wedding it’s not uncommon for the bride and groom to prepare in different areas or even completely different venues. For Jim and Leslie’s wedding this meant I would be at 3 different places throughout the day. It started in the early afternoon with the groom and the groomsmen getting ready at the Hilton. The day was overcast, and the room was lit naturally with a large window on one side of the room. The room itself was painted a soft beige on every wall, including the ceiling. These types of situations are always tricky when trying to find your white balance. The best bet would be to set your camera to tungsten – this will help immensely since the colors of the walls will even influence the color of your flash into a warm tone.
The second location I visited was where the bride and her bride’s maids were getting ready, The Bertram Inn at Glenmoor estates in Canton. This location is gorgeous. The Inn itself has a wonderful style to it, a very late 1800’s industrial-age-elegance. The room the bride was preparing herself in was a large suite, soft blue-ish green walls, a large white ceiling and several windows letting copious amounts of natural light in. This was the perfect room for pre-wedding/getting ready photos.
For the formals, my first choice was to use the attached Chapel, and while we were promised by the staff that it would be available to us for photos, we were disappointed to find out that it had been filled with empty tables and broken glass – and since it’s not kosher to have your bride walking through broken chandelier bulbs, I had to move quick and find a second location for formal photos. Luckily the front of the Inn turned out to be a perfect replacement location. We got lucky and the sun started to peek out of the clouds in the distance, which added warmth, and there was still enough cloud cover that the light remained even over the subjects. In total this provided beautiful, natural light conditions.
Once formals were done, we headed to the wedding venue; La Pizzaria, a beautiful, upscale eatery here in Canton. While the outside of the venue is fairly nondescript the inside, however, is a beautiful, open space with wooden walls and a concave ceiling, painted and lit to look like a spring sky. Wooden walls usually mean you’re in for a lighting nightmare. Trying to bounce light off of shiny, dark materials can prove near impossible. However, I knew I could use a tall light stand and hoist one of my studio strobes into the channeled ceiling and still get good light coverage where I needed it without having to worry too much about color balance issues.
The wedding itself was an exquisite affair with both the wedding party and guests filling the room with excitement and smiles. It’s always fun for me when I get to live and document a day in the life of wonderful people and this wedding was just such an experience – something I’ll cherish and remember forever.
