I bought a used Sigma 12-24, using it on a D3. Taken 2 test shots, with AF fine tune (-6), one at f4.5 (wide open) and one at f10.
A brick wall - forgive me please
f4.5 unsharpened.
and sharpened (smart sharpen)
f10 raw 100% crop:
And smart sharpen:
These are crops from more or less the centre - are these acceptable? They are a little soft but aren't awful after sharpening, although they seem to have a 'pastel'/painted look after sharpening which destroys detail. (a give away of softness before sharpening?)
I must note that the Sigma 10-20 on a D300 and the 24-70 2.8 (obviously) on the D3 were both razor sharp with no sharpening needed. They looked similar in raw to these shorts after sharpening. So there are good sigmas...Just wondering from those who have owned a 'good copy' on full frame, whether this is good or a dud? Cheers.
Edit: Wrong camera!
