Quote:Interesting that the center resolution remains perfect at longer focal lengths but the border resolution drops quite a bit compared to 50 mm.I think I would have substituted "slightly disappointing" for "interesting".......the best end was shown in the guessing game.....it might have been tougher call if we'd been shown the 90mm chart!.......
.........I wonder how the resolution charts of my Sigma 50-150mm F2.8 EX DC HSM would look on a modern sensor? Tested here it did very well..... (I guess on a Nikon 12mp )........... I say that because it is Sigma's older/cheaper generation , albeit without the sealing and IS.
