First Light Sigma Art f1.4 24mm on 6D

Thought this may be of interest to those wanting to purchase this lense.On Landscape its sharp but this test with unprocessed raws clearly shows a better pic at f2.8. Slight corner darkening as it is opened up.What is interesting is that there is not a great deal of difference between the ISO 4000 and 1600 shot.Unfortunately clouds and forecast more bad weather have halted further tests.
Cheers Derek

Thanks for the test. Would be great if you could post some 100% crops from the corners of those shots.

Expecting tack sharp images at f2 or faster on full frame is probably unrealistic. If it performs well at f2.8 even out to corners then that would be a great lens.
