About two weeks after I got my K20, camera and bigma both fell off my monopod onto
asphalt. the bigma didn't seem too much the worse for wear. It's a little stiff for
adjusting focal length, but that's not always a bad thing. It tends to stay where I put
it. When I was looking at my Jupiter+moon photos, I noticed that the bigma photos
weren't as sharp as the tamron adaptall plus two teleconverters. I then remembered that
for the past couple of years I've always been a bit disappointed in the sharpness of the
photos I got with it. The bigma is supposed to be a fairly sharp lens, but how sharp is
"fairly"? I just did some quick and dirty test shots with it, at a variety of
ISOs and shutter speeds. Most of these are 1:1 crops, with a couple showing the full
frame.
Is my lens tweaked, or am I just looking too closely at the pixels?

I don't know, if I'm not looking at the original resolution I'm not sure
what to tell you. However it does seem to be softer, less focused on
the right side of the frame, in this image.
http://www.fluidr.com/photos/ellarsee/7983529238/ My FA 28-200 showed
similar softness on the left side of the frame after being banged around
a lot as my carry lens. I think it's s symptom of optical decentering
because a group got knocked a bit out of alignment.

Don't lose heart, they might want to cut it out, and they'll want to avoid a
lengthly search.
