Hi Jim I have a second Tamron SP 70-150mm F2.8 in quite good condition but the soft focus ring is broken somehow. If I engage the ring the zoom only produced a blank exposure with my film cameras. With the ring set to off position the lens works fine . I don't know if that can be repaired easily? The seller did not tell me that and when I noticed it was too late. If you are able to fix that fault and would not mind the shipping cost from Switzerland you could have it for a low price or in exchange for some other photographic equipment like Tamron KA adaptall2 adapter. I have a spare 2x Tamron SP tele converter as well and a manual Pentax adaptall2 adapter with it.
I will make some tests with the Tamron 70-210 SP 3.5/4 zoom + SP 2x teleconverter on the K10D for bird shots and hope for a usable Background rendering, the SP 500mm Tamron mirror lens was just not good in this regard. Do you have any experience with the Tamron SP 28-80mm 1:3.5-4.2 27A zoom? How well it does on the Pentax DSLR at 28mm?

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.
