It's hard to visually detect cropping in the finder of a camera. For the
cost of a roll of film and maybe some batteries you could get a very
good idea.
I have only a few DA lenses.
I use the XR 40mm on film bodies regularly and find very slight
distortion along the edges of the frame, more

Steve nailed the reason you can't simply go by film camera impressions.
Stopping down will increase the effective image circle, which is not a
bad thing for macro anyway. However, the 35mm would have had an
effective FOV of 52mm, so why not simply use a 50mm macro on the

Has anyone
I tested the new 24/70/2.8 wide open against a brick wall just to make sure it
had no glaring faults. I used the K3 and was amazed at the edge and corner
sharpness. Then it struck me: I'm not seeing the edges. I won't know how good
it really is until the K1 arrives.

They also leave off the 50 f1.4 which is current, at least in the US and
the 35mm f2.0 which was current in Japan, last time I looked, thought
that seems to change from week to week.

Ricewhine has a split personality. I'd suspect that he's a Canon plant,
except, Canon doesn't care what Pentax does. So I'd take any of his
testing with a large portion of salt.
