A zoom lens is a type of camera lens that is offers the photographer a useful range of different focal lengths in a single lens. This is in comparison to a prime lens, which only offers a single focal length. A zoom lens allows for quick and easy re-framing of a scene while staying in the same physical position. Sigma offers a line of over 20 zoom lenses for DSLR photographers, ranging from wide angle zoom lenses, supertelephoto zoom lenses, and high-zoom ratio all-in-one lenses for both full-frame (DG) and APS-C (DC) digital cameras.
In case you were ever wondering how many of our smallest lens equal one of our biggest lenses, and how our lenses size up to a cardinal or a 16 oz cup of coffee, we present the Holiday Season 2013 Sigma Lens Comparison Chart! Here’s our entire lens lineup, to scale.
Prime lenses are designed for exceptional imaging at a single focal length. Unlike zoom lenses that easily span a given focal range and variable field of view with a twist of the zoom ring, the field of view and focal length remains constant. If you want to take in less of the surroundings with a given prime lens, you’ve got to physically move closer, and to take in more of the scene, you’ve got to back up. But of course, as you move, the angle of view remains the same all the while.
The Sigma 50-500mm F4.5-6.3 APO DG OS HSM is one of my favorite lenses of all time. My copy has been there by my side shooting in rain, snow, freezing low temps, scorching high temps and more delivering the sharp images I need month after month.
Iceland has long been on my list of photography destinations so I was very excited to finally get a chance to explore the country as well as try out the Sigma 12-24mm. The landscapes were just breathtaking and I got an opportunity to photograph the many waterfalls of the country. The lens quickly proved itself as I was able to compose and recompose quickly given that I was often very close to the falls! One of my favorites is a triple waterfall near Mt. Kirkjufell (shown above). While I normally use split neutral density filters to balance a scene, I decided instead to blend two exposures (one for the sky and one for the foreground) because of the mountain protruding on the right hand side. A split ND filter would have unnaturally darkened Mt. Kirkjufell so an exposure blend was the best option in this case.
Working with people in general is such an honor for me. As a portrait artist, I photograph people of all ages. I can’t honestly say I have a favorite age group, although I do love photographing young adults and helping them to see their beauty as I do.
The ages of these young people included in this article vary from 11-19 years old. They are from different families and all share the same optimism that comes with being so young.
When I set out to do wildlife photography, I always have my Sigma 300-800mm lens with me mounted on one camera body and the newest addition to my arsenal; the Sigma 120-300mm mounted on another. I absolutely love the versatility and reach of that combination. It is unmatched by any combination on the market today. I have always used both lenses for a while with great results, but I wanted to see how the budget friendly Sigma 150-500mm worked in the field because sometimes, it is nice to travel light! Another big factor is that many people simply can’t afford the higher end lenses and I would love to give them another option, but I did have a few questions myself that needed to be answered. Was the lens sharp…..even all the way out to 500mm? I set out one morning a few weeks ago and started testing the lens out on simple portraits like the one below. I patiently waited for the bird to walk into some nice sand.
I have been looking for an intermediate telephoto zoom lens to add to my lens arsenal. I have owned the Canon 100-400mm lens for a while now but I have never been happy with its sharpness or overall performance and the push pull mechanism for zooming was not very smooth and made tracking while zooming difficult. I was looking at 70-200mm f/2.8 lenses but I felt that I wanted a bit more reach for an intermediate telephoto zoom lens. Someone suggested that I try out the Sigma 120-300 f/2.8 and it looked to be a great idea as it fit nicely in my lens lineup between my wide angle lenses that ranged up to 128mm and my super telephoto Sigma 300-800mm f/5.6 lens.
