Portrait photographer Julia Trotti recently put together a useful comparison video for beginners where she captures portraits using a crop-sensor camera and her most-used prime lenses: a 24mm, 35mm, 50mm, 85mm and 135mm.
Plenty of people have done comparisons like this using full-frame cameras and, in fact, Trotti did that comparison first. But after publishing that video, the most common request in the comments was to do a follow-up on a crop-sensor body. Given how much more affordable and accessible APS-C cameras are, her audience wanted to see how the most common primes would be affected by the crop when capturing portraits.
For this comparison, she used a Canon 7D Mark II (RIP) and shot every photo at f/2, since that’s the maximum aperture of her Canon EF 135mm f/2L USM. The other lenses used are the Sigma 24mm f/1.4 DG HSM Art, Canon 35mm f/1.4L II USM, Canon 50mm f/1.2L USM, and Canon 85mm f/1.2L II USM.
Sure, you could extrapolate this comparison using the equivalent focal lengths, but nothing can substitute for a straight-forward comparison so you can see the difference side-by-side, and Trotti did a very thorough comparison. She captures full-body shots, followed by half-body shots, followed by headshots as both field of view comparisons and by matching the framing.
Check out the full comparison video above to see the kind of portraits each of these lenses produces on a crop and full-frame body. And if you like this style of video, visit Trotti’s YouTube channel for more useful comparisons like 35mm vs 50mm for travel photography or 50mm vs 85mm for portraits.
