Sigma Trio of f/1.4 Prime Lenses Review

Have you heard about Sigma’s lineup of fast, affordable f/1.4 prime lenses for Canon M, Sony E and Micro Four Thirds cameras? The set includes the 16mm f/1.4, 30mm f/1.4 and 56mm f/1.4. Here’s a specifications review that features images by world renowned photographer and Sigma Ambassador Jim Koepnick.

Sigma’s three fast primes cover the focal length sweet spots from wide-angle to portrait. Because the available camera models have slightly different size sensors, the effective equivalent focal lengths depend on the lens mount.

In Canon M mount, the 16mm, 30mm and 56mm focal lengths translate to 26mm, 48mm and 90mm respectively. On Sony’s APS-C size E-series, the equivalents are 24mm, 45mm, and 84mm. And for Micro Four Thirds systems, the results are 32mm, 60mm and 112mm.

All models feature fast f/1.4 maximum apertures for low light and for optional intentional reduction of depth-of-field (background blurring). The large aperture and quiet focus make the Sigma Trio ideal for recording or streaming video.

Sigma Ambassador Jim Koepnick, whose work is showcased in this article, is an independent digital journalist specializing in aviation, sports and street/documentary photography. Based in Oshkosh, WI, Jim is widely recognized as the premier aviation photographer. Jim uses Sigma lenses in his home video studio.

“The mirrorless f/1.4 trio of lenses from Sigma are small and light, so they fit perfectly with my Sony a6500 for recording video in my office,” Jim told us. “It’s great having the ability to use different focal length lenses with recording Vlogs,” he added. “Sometimes I prefer the wider 16mm if I’m demonstrating a technique; other times I can change to the 30mm or 56mm when I only want to concentrate on my face and what I am talking about.”
