Just use the same lenses to test another *istD in the shop and see.

Upon taking a bunch of rather soft shots, I've just been testing my ist D's AF. It seems that with the Sigma EX 28-70 2.8 (which I've not had any AF problems with my 5n), even though the camera says something is focus (using single point/ spot AF), the camera consistently misses the focus (tested on text). Manual focusing yields the usual sharp focus I'm used to getting. Batteries are full, btw.
Does this mean I should return the body for a new one, something is wrong with my lens (I don't think this is the case..), or something else?
Please advise.
Thanks, Ryan
