Which picture looks sharpest. Left to right 1.2.3.4.
Thanks for your help.

Thanks for your help.
wot he said..No 1 is the sharpest, but artificially so. The 4th is less sharp but to me sharper than 2 and 3 and more natural.
Interesting results.I want to buy a Sigma 150-500 lens, hence the tests, but unless anyone can come up with a reason it seems I'm wasting my time.
What focal length and aperture were used? I assume that this was kept consistent with all of the shots otherwise the entire test is a waste of timeWhen cropped to the same size the Canon seems to win. Amazing.
