I have crappy eyes too. Good contrast when wide open is a big help.
I've not had a K24/2.8 to try. The A24/2.8 is fairly easy to focus
for me, but the FA20-35/4 is actually easier: it's got more contrast
wide open than the A24. The FA35/2 is the easiest ... it's wide-open
contrast is the best of all the lenses in this focal length range
that I've tried (including the FA31, for that matter).
Technique is what matters. Learn to manual focus by watching the in
and out of focus transitions as you turn the focusing ring, rather
than trying to judge a static image with small, slow movements of the
focusing ring. With a bit of practice, you can hit the best focus
point easily even with a Coke bottle bottom... ;-)
