That's one hell of a camera. I sold the EOS 1RS and kept this one. Dead quiet and always spot on when it comes to AF and metering. Has given me some of my best pictures.
Agreed, a good camera. Mine still works and the batteries remain available. The eye-controlled focus was further refined in the EOS 3 but then abandoned. Apparently, eyeglasses, contact lenses, and even lens implants would confuse the system. Cheers, Peter
