>>3867629He’s talking about eye-control autofocus. Ie, it has a mode where the camera will focus on the AF point your eye is looking at in the viewfinder.
It’s kind of neat, but—at least with my eyes and my shooting style and my experience on the lower-end EOS 5 and EOS 7NE—I’d rather just have a joystick to let me select my AF point using my hands. I usually just turn it off.
That being said, I also sometimes like to shoot with a modern film SLR like those. Sometimes you want the specific aesthetics (or some other feature) of film but you also want the convenient ergonomics and handling of modern cameras, and you want to be able to use all of the fancy high-end lenses from your DSLR kit. I’ve got a thread of Velvia photos up on the board somewhere right now and those were all taken on that aforementioned Elan 7NE.
