During this portrait photoshoot, I am comparing the Sony GM 135mm f1.8 vs Samyang AF 135mm f1.8 vs Sigma 135mm f1.8 Art DG HSM. I am using all 3 lenses on one Sony A7IV camera body to make sure we have identical settings during our tests. Watch my comparison video below to see SOOC, 1:1 views of all the photos. I share comparisons of the image quality, sharpness and bokeh. I also compare the AF performance and autofocus accuracy to see who makes the best 135mm prime for Sony cameras.
