Dear friens,
Pl. share your views regarding
Sigma 70-300 APO v/s Canon EF 75-300 USM lens
They told me that this APO tech. is simillar to "L" of canon tech. A low dispersion coating.
Pl. share your views in this respect which one would be better. Both are simillar pricing.
Sigma has APO & canon has USM. How do U weigh them?
