I can confirm that the Pentax 15mm is not terribly sharp wide-open. I
remember that the sharpness increased and light falloff reduced dramatically
at f/5.6 and by f/8 they weren't a problem. This lens holds a lot of detail
when stopped down, especially at high contrast due to SMC. My PUG pics
for Oct 2000 and Jan 2001 were shot with this lens.
I sometimes wish that it had at least 6 aperture blades, and a slightly
deeper hood. And a more sensible choice of built-in filters (grumble). F/2.8
and internal focussing would be nice, too (15mm limited, anyone?:)
Cheers,
