I have this lens (the 103A)
And I think it's about time I tried it out.
Will this adapter do the trick?

It says nothing about infinity focus etc. is there anything I need to look out for in adapters?

I bought the smc m200 1:4 shortly after and never got round to trying the Tamron, should I bother? It would be nice to have a better zoom than my modern Tamron 70-300.

Probably better off with a genuine Tamron adaptor. This one looks as though there's no aperture lever, so I'm guessing it will just stop the lens down and all composition/metering would be done at your chosen aperture.

A PK adaptor will at least allow you to compose with the lens wide open, even if you need to use stop-down metering.

This may be your cheapest option.

I have no idea how your lens would compare to your M200/4, but I'm sure John will be along in a moment to extol the unequivocal superiority of Pentax optics.

The lens should be fine but the adaptor is not a PKA adaptor - it will not meter properly with a number of the digital SLRs. You would be better off with a proper Tamron PK (cheaper) or PKA (expensive) adaptor.

Amazingly, the PKA adaptor can run to 50+ on ebay, which could be almost as much as a DA 50 -200.

Not sure of the quality of this version of the Tamron zoom - generally, the SP versions are the best of the Adaptall range.

Thought I did quite well with THIS yesterday, the lens is nowhere as good as my SP 70-210mm f3.5 but worth it for the mount alone.
My 2 most used lenses are Adaptall 2 mount - 90mm f2.8 and SP 70-210mm f3.5. Had my 35-80mm f2.8 lasted more than 2 minutes it would probably be all 3 in my bag and not much else.

Wish I'd seen that myself, would have earned a quick 50 reselling the mount alone.

Yes, not a bad purchase, maybe this one was better though ... one sold last week for 202.00

You can be lucky sometimes. I picked up an M42 telescope adapter for $10 and it arrived with a genuine pentax K-mount adapter attached.

Thanks Guys,
It seems to be a good lens, I imagine it would exhibit much less softness wide open on a K10D as the edges would be cropped out? is that right?
Anyway, I'll hold out for a 'proper' adapter.
The SMC M 200 is an exquisite lens (by my standards) but it is often not in my bag because I can't carry everything, so I wondered if the zoom might help out.
The Tamron 70-300 is simply never in my bag despite being really versatile. I'm not entirely sure why, it's been such a long time - I've forgotten, but I think I kept coming home disappointed.
