The ability to focus by eyeВ was just too much to resist. In fact, I liked using it so much that I switched from aВ Nikon to a Canon system.

I got my first taste of eye-controlled focus on the EOS Elan II E, and instantly fell in love with it. The Canon EOS Elan IIE, introduced in 1995, had a 3-point autofocus system with eye-controlled focus. And I have to admit, I'm right there with them. There weren't many in between.Д®ven today, whenever we review a Canon camera, someone will post a comment expressing a desire forВ Canon to bring back eye-controlled focus. It promised вЂfocus where you lookвЂ™ functionality, meaning you could activate your AF point of choice just by looking at it.ДЄs I recall, there were generally two sets of users when it came to this technology: those for whom it worked, and those for whom it absolutely didn't. The system made its debut way back in 1992 on the EOS A2E, and remained part of the Canon system until the EOS Elan 7NEВ in 2004.

But before we had those things, we hadВ CanonвЂ™s eye-controlled focus, a technology that made its appearance in film SLRs, but which never quite madeВ the jump toВ digital cameras.ДЇor those unfamiliar with eye-controlled focus, let me provide a quick primer. Over the past few years, we've becomeВ spoiled byВ a lot of great autofocus technologies like face detection, tap-to-focus, and subject tracking. The Canon EOS 5 (known as the EOS A2/A2E in the Americas) was the world's first SLR camera with eye-controlled focus.
