scoobert:
this is my 7D with a tameron 10-24.
why is the focus so far off?
does my camera hate this lens?

daveheinzel:
That image is comparable to my best images with the 7D when I shoot at such a high ISO. That's why I usually stick with 1250 or less. Focus looks fine though. Try at a low ISO and see if that makes a difference. Corners on lenses that wide are usually a bit distorted.

scoobert:
running a lower ISO will sharpen up the image?
looks like my other lense does it too...

neuroanatomist:
Have you done autofocus microadjustment for those lenses?

What are all those little boxes in the second image, with things like Tmax and Ektar on them?   :P

scoobert:
how do you do that?

those little boxes are some type of permanent recording memory, tiny unusable photos. one time use, can you believe it?

actually that store has a huge film camera customer base.
