I started suspecting it a while ago, but it wasn’t until earlier this evening that I confirmed my suspicions of front-focusing with my Tamron 17-50mm. It’s not that bad at wide-angle, but at tele (50mm), it’s very noticeable. I’ll have to give Downtown Camera a call in the morning to see if they can do anything about it. I’d rather not be weeks without my most-used lens and send it off to be calibrated.
I focused on ‘TV’. As you can see, the lens seems to have focused in on the author’s last name instead. The 50mm Nikon f/1.8 isn’t exhibiting any issues, so I don’t think it’s the camera.
