I recently purchased a Tamron 17-50 and discovered it had a back/front focusing issue. I was disappointedsince I was really looking forward to using this lens a ton this summer. I suck at manual focusing so this is something I really need to do.


If anyone hassent oneof these in for service,or any tamron lens for that matter, can you fill me in on your experience? I have been lucky and have never sent any lens for calibration and I am looking to ease my mind. I purchased the lens from B&H. Should I contact them first? Sure wish I owned a camera with Microadjustment capabilities(or at least I think that would solve the problem).


Thanks,


Jayson
