Steve’s Favorite Lens: 

My absolute favorite lens in the Sigma line up would have to be the 120-300mm f2.8 Sports lens. It’s incredibly sharp, fast and it’s zoom is amazingly versatile when shooting fast moving sports that frequently change distance. For low light sports such as ice hockey or night games under the lights, there is no better lens. That being said, if I change the question around a little bit and was asked if I could only have one lens for the rest of my life which would it be, my answer would definitely to be the 24-105 mm f4 Art lens. It’s the most well rounded lens in my arsenal and covers just about every situation. As a portrait photographer it’s by far the most used lens I own.

Liam’s Favorite Lens: 

What is my favorite Sigma lens?  Well that is a very hard question to answer and I think my answer would change monthly, weekly or even daily. But as of today my answer is the Sigma 12-24 F4 A lens. Many might think I love it for shooting landscapes, and I do, but i actually shoot it more for action. Currently I am on assignment in Portillo Chile shooting skiing and I love the unique angle of view it gives me. I can get some great story telling shots with the lens and it’s perfect for giving viewers a “sense of place”. I shoot it on both full frame and crop sensor camera

David’s Favorite Lens

The Sigma 105mm F2.8 EX DG OS Macro HSM is a superb lens for all kinds of macro, from flowers and fungi to many of my Curious Critters white-background shots. This prime optic is sharp throughout its range, quick-focusing, and nicely compact for a 1:1 macro. Add to that excellent optical stabilization. For these reasons—and the many amazing subjects this great glass has allowed to capture—the Sigma 105mm macro is my favorite lens.

Judy’s Favorite Lens:

I can’t live without my 24-105mm 4.0 lens. Absolutely my favorite lens ever. I don’t often travel to a location where I can only take one lens, but should it happen, hands down it would be the 24-105mm. Sharp as a tack, fast and smooth transition in the zoom, this lens covers all my needs for perspective. Wide angle at 24mm and long at 105mm and then everything else in between. The 4.0 aperture is constant throughout the zoom making it a very versatile lens.

Roman’s Favorite Lens:

I have owned the Sigma 300-800mm lens for over 12 years now and it still remains my favorite lens! With its unrivaled zoom range and extreme focal length, it allowed me to capture wildlife images that I never thought possible.  From the migration of the wildebeest in Africa to small shorebirds closer to home the 500mm’s of zoom versatility allow me to compose and recompose quickly while the maximum f      ocal length allows me to capture the intimate behavior and interaction of my subjects without intruding.  This lens is the ultimate choice for wildlife photography.

The new Sigma 100-400mm Contemporary lens has become my favorite lens. It’s replaces my 70-200mm lens that I have always used for telephoto zoom. I love the added reach in such a small package.

Andy’s Favorite Lens:

I happen to love the 24-105mm Sigma lens –  I use it most of the time once my portraits are done (which I shoot with the 70-200mm Sigma).  I like the sharpness, focus speed and crispness of the images I take.  The 24-105mm range is just perfect for both candid and dance photographs at weddings.

Robert’s Favorite Lens:

The 120-300 sports lens goes with me all over the world in my pursuit of wildlife images, from Africa to Japan to Alaska. It has the perfect combination of super quick and responsive AF, with a fast maximum aperture that gives me the ability to use action stopping shutter speeds, even in low-light. The lens gives me awesome sharpness in a hand-holdable package with good reach, especially with a crop sensor camera that gives me the equivalent of a supremely sharp and quick 180-450mm f/2.8! There is nothing else like it on the market today, its a one-of-a-kind and my favorite Sigma lens.

The 50mm F1.4 Art lens is my absolute favorite lens. Technically speaking, it’s a great choice for me since I often shoot in small spaces like hotel rooms and my studio. The sharpness are reliability are unmatched. Emotionally speaking, the 50mm art allows me to be close in proximity to my clients which allows for better communication and building of trust, especially with intimate portraits.

James’ Favorite Lens: 

Being a portrait/fashion photographer and choosing the right lens for me is determined by what type of job and the final look i am going for.  I need to think about how much depth of field, and how much image compression i need and how far away from the subject I will be.   In the past the difference between a portrait photographer and a fashion photographer was depth of field, portrait photographers shot at f5.6-f8 And fashion photographers shot everything wide open.   For example, shooting fashion catalogs we always used wide open apertures to isolate the subject from the background in order to make the clothing stand out . The new Sigma prime art series lenses allow very shallow depth of field for that fashion look.

My all time favorite lens is the 85mm 1.4 ART  because it has the perfect balance of working distance to the subject, compression of backgrounds,  and very shallow depth of field.  But it also has a minimum focus of under 3 feet for close ups of faces, so now i can give my high school seniors that fashion look!
