With the popularity of mirrorless cameras from Sony, Fuji, Panasonic among others, more and more Canon users are either changing systems or wanting to try these new cameras. That in turn, is making adapting lenses more popular than ever, especially as autofocus performance continues to improve and includes many native features like Continous Eye AF (in the case of Sony cameras).
Sony's latest mirrorless cameras are much improved when it comes to shooting with adapted lenses from other manufacturers. To test just how well it works, photographer Manny Ortiz got his hands on a $5,700 Canon 200mm f/2.L IS lens and mounted it to his new Sony a7R III camera.
When the Sigma 135mm f/1.8 was announced, I was very excited and eager to get my hands on it. Although I haven't had much success with adapting autofocus lenses to my Sony a7R II in the past, I thought using the official Sigma MC-11 adapter with the Sigma 135mm f/1.8 would bring me better results, since they are optimized to work together.
