Tamron 28-75mm f/2.8 hmm, not happy.

Agree with sending it back. I would be comfortable ordering a different copy. As you see, a lot of us own this lens and yours clearly has a problem. I heard all good things about Adorama's service.
 
I got a sharp copy after a few tries. The copy I have, after my less than scientific testing with a rented 24-70, was that the Tamron was sharper at 5.6 and above.

You have a bum copy, which happens often with third party lenses.
 
I hope I didn't get bad copy. If I did I hope Adorama is good about it because I bought it used.

Our returns guarantee gives you a full 30 days to try it out - I think you already know that it isn't living up to expectations....... :(

Please drop me an email with your order number and I'll have a pre-paid label sent out for you to return it: [email protected]

I have performed a more scientific test.

All are at 75mm focal length, focus distance at about 5-6' which is closer than the 12' of the previous pics.

While the 2.8 performance in these photos is better than the 2.8 performance in the previous photos. It's still much worse than I expected.
 
Agreed -- back it should go! I'm sure Adorama will make good. If you had bought it new, Tamron has a 6 year warranty and excellent customer service.

EDIT : I didn't see Helen's note. :thumbup::thumbup:
 
I had that lens, and while I wasn't happy with its slow AF or slight softness and CA problems, I definitely agree you have a bad copy, or are having focus problems.
 
Exciting news!!

the new lens has arrived from Adorama!!! I will be posting more examples tonight!!
 
I'm not sure about the one they JUST sent but the one from the examples above is the non-built in motor version. Using the camera body focus motor.
 
I tried a Tamron in that range, it sucked and constantly locked up and had to be removed/installed.

I went with the Sigma 18-50 f/2.8 HSM OS and never looked back.

I looked into that as well but 50 is not quite tight enough for me. I'm usually in the 35+ range for most of my shots.
