I don't own an EOS R but may in the future, and the relative touch and drag AF method sounds very interesting to me. I did a bit of research on this sensitivity issue and there seems to be quite a divide whether people find it useful and fast or too slow. So I'd like to ask a question:I know it'll never happen but I REALLY wish they'd make touch AF have a "sensitivity" setting in relative mode. The cursors moves too slow. If I could adjust sensitivity I'd like touch AF better than a joystick but I hate having to swipe my finger tons of times to get the cursor across the screen.
The way I would assume that it *should* work in relative mode (but maybe doesn't, maybe you could clarify), is: Say, the bottom right part of the screen is selected as touch and drag AF area, and it's set to relative mode. Let the current focus point be on the top left corner of the image, and I'd like to move it to the bottom right, which is the furthest possible distance that could ever be needed. I would then want to touch the AF focus area at the very top left corner, i.e. the center of the screen (having selected only the bottom right part of the screen for touch and drag AF), and quickly swipe to the lower right corner of the screen (= the lower right corner of the touch and drag AF area). And this should be enough to move the focus point accordingly to the lower right corner of the image. This is what I would expect and this would be (as far as I think without having actually used the R) enough sensitivity to quickly change focus point to any desired point without the need for doing multiple swipes. So my question is:
a) Does it indeed require more than one full swipe across the entire active touch and drag area on the screen to actually move the focus point over the entire image? (This would indeed be a bad implementation.)
b) would you simply prefer not to actually utilize the entire active touch and drag area but rather move your thumb by only a few Millimeters (just like you would with a joystick) in every swipe for not having to move your thumb around so much?
(This wouldn't bother me so much as the swiping distance covered on a current smartphone much exceeds the dimensions of a quarter screen on the EOS R)
Many thanks for clarification!
