Somewhat Secret Superpowers of Camera lenses

Everyone knows supertelephoto zoom lenses are great for long-reach photography at widest, like wild birds. Here, the Sigma 150-500mm is trained on an American Anhinga, at 500mm, wide open at F6.3.

The greatest thing about interchangeable camera lenses is the variety of optical designs, from ultrawide to supertelephoto and everything in between, that offer an incredible amount of variety for visual expression, creativity, and optical performance optimized for different photographic situations. And while it may be sometimes completely and totally obvious what types of photography a certain lens excels at—for example, everyone knows that Macros are designed to capture close-up details; telephoto lenses are great for long-reach wildlife and sports from the sidelines—many styles of camera lenses have lesser-known secret superpowers that can be called upon to make a photo. Let’s take a look!

The Challenges of Photographing in Natural Light

© Judy Host 2013 | Lens: APO 70-200mm F2.8mm EX DG OS HSM | Aperture: F 7.1 | Shutter speed: 1/200sec |  ISO 800 | Exposure mode: Manual mode | Focal length: 157mm

The challenges of photographing in natural light can be many. I don’t always get to choose when I photograph, especially because I photograph children and sometimes the best time for them is in the middle of the day. When that happens there are a few things that can help to make this actually work pretty well.

What is a Zoom Lens? And why and when to choose a Zoom Lens?

Sigma offers a great variety of zoom lenses. (Lenses are not shown to scale in this display.)

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.

Prime Time: Focus on Fixed Focal Length Lenses

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 Magic of Iceland

© 2013 Roman Kurywczak | For the foreground: Sigma 12-24mm | Focal Length: 12 mm | ISO: 100 | Aperture:  f/22 | Shutter speed: 1/3 sec. For the sky: Sigma 12-24mm | Focal Length: 12mm | ISO: 100 | Aperture: f/22 | Shutter speed: 1/5 sec.

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.
