See, now that makes sense and could be really useful. I can't imagine that eye detection would be useful for moving individual focus points with so many of them available. If it was only moving the focus point and not feeding info to the AI, I imagine the selected AF point would always be lagging just a bit behind where my eye was looking (especially if I'm looking around quickly) which would become really annoying really fast. This makes much more sense.I think people are misunderstanding what this will do. It won't move your focus point like a joystick or like the way the old EOS 3 did, it will simply feed back to the AI within the camera to help guide it to automatically detect what object you want in focus and where to start hunting for eyes, etc. You might even be completely unaware that it's doing anything, it will just 'magically' be able to focus on things properly. This is why it's only for mirrorless and won't work on a DSLR.
Amount of af points isn't the issue (we won't be going back to 3 or so anyway), it's that you need to be able to compute accurately where the person is looking at. If you can manage that then the more af points the better.
Technical reasons – as pointed out above, size of the needed sensor and EVF.
The problem is the points are so close together with image-sensor based AF requiring higher precision in determining exactly where a user is looking.
Same here with ~-2 spherical and -2.5 cylindrical - stunning that this works. And I support canonical, that in 2019 it might be just better than the old implementations.Works very well for me wearing corrective glasses on my old Elan 7E. A new 2019 implementation of Eye-ControlledAF should be absolutely phenomenal.
Yeah - it's like using your eyes which are focusing automatically on the object/subject of interest (at least up to ~50 years of age .I think people are misunderstanding what this will do. It won't move your focus point like a joystick or like the way the old EOS 3 did, it will simply feed back to the AI within the camera to help guide it to automatically detect what object you want in focus and where to start hunting for eyes, etc. You might even be completely unaware that it's doing anything, it will just 'magically' be able to focus on things properly.

If you can build a chip which just puts out coordinates calculated from your eye position you have only a little bit processor workload namely to read two 16bit values 10 times a second which is 40 bytes per second compared to 300 000 000 bytes per second throughput for e.g. raw files @ 10 fps.I would say a feature like this also requires some processor workload so not sure it’s used to reduce that. Once an initial lock has been made, the camera still has to track the subject. I suppose next gen processors will be better anyway.
Not for those who wear glasses. I never got Eye control in my EOS 3 to work properly, so I switched it off. Would be great if Canon could revive it in a much improved version.The original version was so good that many claimed it was telepathic. I think Canons’ got this one in the bag. I can’t wait to see it in a pro body.
Yep, I had and still have a 7e/ elan 33. It kind of works pretty well. But that was with only 7 point AF and it was a little hap-hazard. It mostly worked if you calibrated it regularly. I wonder if Canon have advanced the tech since then and made it more accurate. I also wonder if it's works but moving the points about using eye movement gestures...much like swiping. As opposed to the look at this point and hopefully the system will select the same point....I would not complain one bit if ECF came back. Loved it on the EOS 3 and Elan 7e.
I so loved the eye control focus feature that was prevalent on the EOS-3 body and have missed seeing it on any subsequent camera(s). Calibration for user's eye was simple, even for eyeglass wearers and for me, it just worked. I have been disappointed that, for years now, Canon has chosen not to include this great feature. I, have no doubt that many CR readers are not familiar with this feature set. I, for one, was always amazed at how well it worked. It was an available option on the EOS-3 and Elan 7e bodies, but you did not have to employ it, opting instead, if you chose, for regular auto focus. Yes, please make it available again, Canon. I miss it.
Sorry you had problems, as an eye glass wearer, getting it to work. I, also wear glasses and never had a problem calibrating it while wearing my eyewear. Don't know the reason for our different experiences but I had two EOS 3 and one Elan 7e bodies and the feature worked in all three for me. If they offer eye control focus in a future Canon body, perhaps, as you say, it will be much improved in the newer version.Not for those who wear glasses. I never got Eye control in my EOS 3 to work properly, so I switched it off. Would be great if Canon could revive it in a much improved version.
