Sigma 17-70 f2.8-4 OS Sharpness
I am probably about to purchase a Sigma 17-70mm f2.8-4 OS HSM Macro lens. The only issue is that I am a little concerned about the sharpness of the lens. Because I could not find a lot of information about it. If anyone could tell me about it or could show me some pictures just to reassure me that be great!
Thanks in advance,
