I still want a thumb controlled joystick.
it is not mutually exclusive. And users can switch ECF on or off as desired - even on the 1990''s Canon SLRs there's a simple, straightforward hardware switch: OFF / ON / Calibrate.
"The EOS 3 stands out because of its extraordinary autofocus system, which clairvoyantly reads your mind to know exactly which of its sea of 45 AF sensors to use for each shot. The EOS 3's AF system is so much faster and easier to use and to set than anything available today.
When I first picked it up, I was astonished at
how it just knew where I wanted it to focus, without me having to to do anything. No matter if I wanted to focus on the obvious part of an image, or a subtle, low-contrast item off to the side, the EOS 3 somehow just knew, and magically used the correct AF sensor every time.
Then I realized that it has Eye Controlled Focus, a name which doesn't do this system justice. It should be called "
mind-controlled autofocus," since you don't have to do anything to control the AF system other than just shoot. The AF system is constantly looking at your eye, and already knows where you're looking when you press the shutter, so without you even having to think, the EOS 3 already knows where it needs to focus, and it just does.
The EOS 3's AF system is far ahead of today's cameras, which no longer use this expensive system. With newer cameras, we again have to slave through dicking around with knobs and dials to choose AF points, something the EOS 3 does all by itself by magic.
If for some reason you dislike the magic mind-reading AF system, it's easy to set back to old-fashioned manual AF point selection, or also can be set to auto AF point selection, which works as well as the same non-mind-reading modes of today's cameras."
