K100d-s and Tamron problem...

Hie i have a problem with my K100D-s using a Tamron

Just bought a Tamron 28-75 f2.8
And the camera just misses the focus point.
im shoting in "center focus" mode, but the results are very inconsistant.
mostly backfocusing

When shoting in MF mode i get realy sharp results, but as said the AF just sux.

Whos to blame... camera or lens??

The original lens Da18-55 works fine. no problemo!

Please help so i know how to attack the prob

Thnx / Rikard -sweden

Most likely the lens is the culprit. When I got mine the first copy was backfocusing. I sent it back and got a replacement. The second one is spot on accurate. I suggest you read up on focus testing on these forums and verify what the lens is doing. Then send the lens back a get a replacement. Good luck.
