Just used the sharpness slider. Sigma software does a very good job of sharpening without accentuating artifacts.

The clean up at 300mm x2 with SPP only is quite fantastic. What do you do actually to get this sharpness?

not as fast as WHICH nikon? It has nothing equivalent... Nor Canon

The lens seems to have virtually no CA/Laterial Color of any kind, even when used with Sigma's 2x converter (which also says something about the quality of the converter).

I just got this lens, and the results are good. not as fast as nikon, but for my kind of work its fine. your results seem to stand up to what I found when testing it out. Mac

300mm test redone due to initial focusing error.

Focused of the spiral vent fins.
