Hello, I am considering the following lenses for D7100
• Sigma AF 17-70mm f/2.8-4 DC HSM OS | C
• Sigma 17-70mm f/2.8-4 DC Macro OS HSM
• Sigma 17-50mm f/2.8 EX DC OS HSM
I have read that there are firmware and/or focus calibration issues with them. I know that there are issues with any lens, as well as the chance of a bad copy
However, is there a greater chance/higher % with these Sigmas, especially, with a D7XXX?
Is there a greater chance with one of the above, as compared to the others?
I would appreciate any feedback, thank you for your time
