Hello everyone!
I recently bought a Tamron 28-75, after having seen all the good reviews on this forum and all. I'm a beginner and actually have no idea what kind of sharpness I should expect from such a lens. PLUS, there is always the "bad copy" problems, where some people complain about their copy not being sharp enough or having a bad AF etc... so I'm getting paranoid as well. I'd say I'm glad to have this lens, but still the question remains, do I have a good "copy" of it ?
The AF seems fine enough, sometimes backfocuses a bit, but it may be just me not yet being used to the K7 AF (so far I have been shooting mostly with the 10-17 and 50 f1.7 M).
So I went for a walk and took a few pictures, a lot of them with the aperture open wide, which I think gives a nice bokeh. Here is the Flickr album, all the exif are copied from Lightroom. All taken with a K7, with 3-star Jpg straight from the camera :

My question would be : how does it compare with your copy of the lens ? What kind of test could be more revealing ?
PS: Sorry moderator, this is not really a "troubleshooting problem", maybe should be in the beginner's corner?
