Have taken a few shots using my Tamron 90mm for comparison purposes. The only difference between each shot is the aperture setting. Everything else remained untouched.
I used the liveview to get the sharpest focus I could and the "50" was my focus point.
All images are straight out of camera with no PP
[MENTION=9753]Scott Murray[/MENTION] and [MENTION=6277]Don Kuykendall[/MENTION] let me know what you think.
First shot was at f 7.1
Note how the focus on the lines is above the 50 mark on either side and then below the 50 on the outside (right).
The next is at f 9.0
Very little difference to my eye. The brighter exposure is probably me holding the off camera flash a bit close.
Then at f 11
f18
f 25
and finally f 40 A bit dark - sorry
