24-105 vs 17-70 dof ff vs apsc
Jul 18, 2013


I am considering purchasing the sigma 17-70 2.8-4 and was wondering how the dof compares to something like the 24-105 L lens. They both have almost the same fl and aperture as the 17-70 on apsc is aprox. 25.5-105mm.

can anybody tell me how they would compare dof wise. I think they should be similar, please tell me if I am wrong.
