Wow. Interesting idea. Now that cameras are computers, how about a
function that automatically sets the lens to the hyperfocal point for a
given focal length and aperture? Otherwise setting hyperfocal distance
manually on newer lenses is very difficult, because a small turn of the
focusing ring makes such a big difference in the focus, and the
distances that are marked are so far apart. The last numerical distance
on the DA 16-45 is 2m/7ft. After that the next marking is infinity. How
do you set a hyperfocal distance of 3m on this lens?
I don't find DOF preview useful. It just makes the screen too dark.
