So...everyone expecting an R1...what does Canon do, announce the R3. 1D build quality, 30 fps, eye-AF functionality, and that is about all that is known at this time. From what I can tell, not only is it enhanced eye-AF, but also AF that will focus on where your eye is looking. This feature has never been too appealing to me as my thought is that I tend to look around the frame assessing the composition. But, maybe you can use your eye to lock the autofocus point on something and then you can look around the frame to ensure composition.
Anyway, fancy new toy coming soon.
