The nice part of it all is you can get "KA" type adaptall-2 adapters to maintain autoexposure on the current crop of pentax DSLRS. jco

I collect Tamron SP Adaptall-2 lenses and already have most of the zooms. I'm quite interested in this specific lens, partly because of its reputation as a very sharp fast conventional optic and also because I'd like to experiment with the progressive variable softening feature (I already have all of the Pentax soft focus lenses). Unfortunately I've never seen one for sale - either it was rare to begin with or those who own one like it too much to sell it! ;<) > The soft focus ring settings 1-3 are nice for full portrait shots > or flower > close-ups with uniform backgrounds.

It's consistent with my results using the Pentax soft focus lenses as well. But there are certain images where the spherical aberration (I think that's what it is) of a soft focus lens adds just the right dreamy/foggy look. > The slower non SP 70-150mm 3.5 Tamron is very inexpensive here but > I can't > say anything about it's quality and if it is similar to the SP one.

Yes, I already have this one, as well as the even more highly regarded SP 70-210 f3.5 constant aperture version which I recently found on eBay. The latter is said to be the best MF zoom ever made in this range. I'm looking forward to comparing it with my Pentax A 70-210 f4 when I get the time. It's amazing how inexpensive most of these lenses are - it seems that nobody is interested in MF zooms any more. Ah well - the joys of collecting are even greater when the cost is reasonable.
