comment:I made a test at maximum open f-stop (same apreture) This lens is definitely less sharp in the center than Sony DT 18-135.
@28 f:4
@35 f:4.5
@50 f:5
@70 f:5.6
@100 f:5.6
@135 f:5.6
This lens has less contrast, more CA, less sharp, more prone to flare, much worse MFD. Comparing to the other reviews I think I god a bad copy even though it looks good on inspection (no dirt inside, looks like it is only little used).
Update: But if I stop down 2 stops to f:8 it really shines. Then it is on par with the DT 18-135.

For FF it is not tack sharp even in the middle wide open. But the same sharpness applies all over the frame. If stopped down to F8 it sharpens up. Some CA can bee seen.

For long reach for FF it has few competitors. The super zooms are not as sharp, no other sharp zoom has this reach.
