Originally posted by rayallen As promised above, I have taken a couple of quick shots with the SMC Tak 200/f4 on my K10D. I have not tried it yet on a full-frame camera but I think it did pretty well on a crop sensor.

Lovely shots - with those Pentax/Takumar reds and rendering, and I particularly like the in-and-out of focus subtleties of the second photo.
There's no doubt the Tak 200/4 is a fine lens, especially for the kind of compositions you've show here. It can produce images with great pop (here's one below on a K-3). My problem with the lens on crop sensors related to using it as a walk around, hand-held telephoto lens, for taking photos of wild-life in parks. The equivalent of 300mm on crop, plus more sensitive digital sensors, resulted in a large proportion of blurred images, even with Pentax's SR. It really needed a tripod to stabilise the set-up. Now the lens is back to the natural 200mm on FF, I'm finding more keepers.
