Hi all! My husband surprised me with a new camera and lens for V-day.:heart:The lens he got me is a tamron 28-75 f/2.8 macro. I've read really good reviews overall about this lens, but there have been concerns with quality control. What is the best way to ensure that I got a "good" copy? I have no "L" lens to compare it to and don't personally know any pros to ask for advice. He bought it online, so I doubt if local stores will be willing to help me with this issue.... Any suggestions? Thanks for your time and consideration!
