I've used the 35-70mm on my *ist-D and Ds cameras with good results. I
haven't tried in on higher resolution sensors, but I expect that it will
produce fine images. I can't tell you anything specific about the
Tokina, but in general when you use a lens that covers the full 24x36mm
frame of 35mm film are usually better on the APS-C sensor size
associated with Pentax DSLRs. This is mainly due to the crop effect, a
lot of lens corner and edge defects are simply not recorded.

Are these lenses usable on any Pentax Digital SLR's? I am currently
investigating at upgrading to Digital SLR.
Am particularly interested in the new K-7 (still waiting for pricing
in Australia) or the K-m.
The feature I liked most about my old SF7 was the "AF spotbeam" which
assisted with auto-focus using the flash in dark environments. Is this
feature currently available on any of Pentax's DSLR's or is this now
superceded?
Thanks PeterD
