So I went back to Prescott park today for a very late lunch, trying to redeem myself. I was a good dubie and even printed up the hyperfocal chart, hoping to get the shot I'd wanted just right.
I *might* have a problem with my EF-S 17-55 f/2.8 IS as pretty much all the shots (manual focus and AF) were slightly OOF. I tried some silly shots this evening outside and found that I couldn't get a sharp photo of some leaves on a tree (not a good test as it was a very low contrast subject). Manual focus nailed it though.
After I post this, I intend to setup a yardstick and a piece of black tape and will test out the focus on this puppy.
This has been gnawing at me for a few days, something wasn't right about the 17-55, when I first got it, all my shots were tack sharp. Lately I've noticed slight sharpness issues.
The 70-200 seems ok though.
