Received the Tamron 17-50 from B&H today. I went with a factory refurbished one they had. I seem to be having an issue with it. The lens is not communicating properly with my K20. It's like its not making contact, and keeps going into manual and asking for the focal length like when i connect my M50/1.4. If i unlock it and twist as in to remove it and then relock it, most of the time it begins to function properly. I tried cleaning the contacts but hasn't seemed to help.

update: after some more use i have realized that even when the autofocus works it is off quite a bit. When i switch to manula i get pictures that are very sharp over and over again while autofocus fails to focus correctly. Some how i knew this was going to happen.

another update: I contacted B&H and he promptly issued the return and UPS is picking it up tomorrow for the exchange.

well appears im getting a refund. perhaps thursday i will buy new, but unlikely.

This actually makes me pretty frustrated, i finally pulled the trigger and picked a lens and two weeks later i have nothing. This just brings up the fact that now i am undecided again on what to get. I'm really looking at the sigma 17-70 again for the extra 20mm. the tamron was appealing two weeks ago before i had my flash, now with the flash the 2.8 isn't so important for indoors anymore. or do i just stick with the faithful da18-55 and get a winch for my rover
