Originally posted by JerD I'm the proud new owner of a K30 and have bought a couple of lenses to go with the kit I bought (body and 18-135).
I posted in the slr lens forum about my dilema with a Tamron 70-300 not locking a focus after 100mm when using the view finder.
I tried today and found that the lens/camera combo seems to lock on in Liveview.
Is this a body, lens, firmware, or setting issue? I'm leaning towards lens, since this is the only lens (so far) to have this problem.
Check the limit switch and make sure it is engaged properly
