Over two decades ago, Canon introduced a very unique feature in some of their film SLRs: eye-controlled autofocus. Recently, the company filed a patent that shows a similar system being worked on. Is it a feature you would like in your camera?
Coming to you from DP Review, this interesting video takes a look at eye-controlled autofocus in the Canon EOS 3, a film SLR from 1998, and examines the prospect of its use in more modern cameras, as Canon recently filed a patent for a new system using the technology. Of course, it's important to remember that just because a company files a patent, it doesn't mean the product will eventually come to market. Still, as cameras gain more and more autofocus points, something numbering in the high hundreds or even thousands, it can be a bit of a tedious and inefficient process trying to select a focus point. If a camera could follow your eye and use that as a starting point once you pressed the AF-On button, that could be a very useful way to get around the issue. Is it something you would like to see?
