Is this the right adapter?

I bought a Tamron 90mm f/2.5 lens and I know I need a:
Tamron Adaptall 2 Adapter Pentax P/KA PK/A PKA
but I saw this: C02300 Tamron Adaptall-II Camera Adapter f/ Pentax K will that one work with manual focus?

Oh and btw... Jesus !@#$! Christ... 10 minutes just to LOAD this page?!?... why do these forums lag so much?

That adaptor will work, the lens will behave like a K-M - on a digital body, you'll need to do stop down metering in manual mode but the lens will stop down & open back up when you take the photo. The K-A adaptor will give you the A functionality - you can shoot in program, aperture priority etc by setting the lens on 'A'.

Neither mount will give you autofocus.

The 90/2.5 is an awesome lens, I have one and simply love it.
