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!

Prime Time: Focus on Fixed Focal Length Lenses

A ring of beach rocks seen through the Sigma 15mm EX DG HSM Diagonal Fisheye with the horizon line near the center of the frame.

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.

Fall Foliage with Sigma’s 15mm F2.8 Diagonal Fisheye Lens

This image was made in the early afternoon when the sun was still high in the sky. By standing under the leaves, I was able to use the sun to backlight them. I shot this image at f/2.8 to blur out the background, drawing attention to the branch in the foreground.Sigma 15mm f2.8 Fisheye, 1/2500 sec at f/2.8, ISO 250.

Fall is my favorite time of year to take photographs, and I always push myself to get out and make the most of the brief window of brilliant color. I have spent the last week chasing fall foliage in the Pocono Mountains of Pennsylvania. This year, after taking the obvious shots of deep oranges and reds, I used my Sigma 15mm Fisheye lens to capture the forest from a different perspective.

I have always wanted a fisheye lens and have always talked myself out of the purchase, confident that it would gather dust when the novelty wore off. Recently, after becoming interested in wide-angle macro photography, I bit the bullet and got the Sigma 15mm F2.8 EX DG Diagonal Fisheye. It’s now been two months and I honestly can’t put the lens down. A few weeks ago, my dad commented that my worldview is becoming warped and I hope he was just referring to the pleasing distortion in all my recent images.
