Testing the Sony a7R III’s Eye AF Using Canon Lenses

Comment

The Sony A7R III boasts some impressive and improved autofocus features. The Eye Autofocus mode is great for locking onto your target, but The Brotographer found that it didn’t work perfectly in the previous a7R II with adapted lenses. In this 12-minute video, however, he reveals major improvements for adapted Canon glass on the latest Sony camera.

The test was carried out on a number of lenses mounted to a Metabones Mark IV adapter: the Canon 85mm f/1.2L II, Canon 35mm f/1.4L II, Canon 70-200mm f/2.8L IS II, and Tamron 90mm f/2.8 Macro.

In what will be music to the ears of Canon/Sony crossover shooters, the Eye Autofocus worked for each of the lenses tested.

When using the Tamron 90mm macro lens, he asks his model to step backward. In this test, Eye Autofocus is still working at 30-40 feet (9-12 meters) from the camera while in a poorly lit room – that’s impressive.

The Canon 70-200mm lens seemed to have trouble using Eye AF at 200mm when back-focused but not so when front-focused. Regular AF also works well.

He also found that the Canon 16-35mm f/4 lens and Tamron 150-600mm G2 lens benefit from Eye AF, but these lenses aren’t featured in the video.
