The Sony a7R Mark III is here and we get our hands on one for a few hours while at a press event in New York City. First impressions are positive - The camera's Eye AF function seems reliable - which we used for quite a few images in this gallery, as well as the lock on AF. Also everything here was shot using the new 24-105mm F4 G OSS lens. We'll update with more images soon when we get one in the office and can process Raw files.
