Sigma 105/ f2.8 EX vs Canon 70-200 f/4L USM
Hi, folks, I have this macro lens and I would like to buy this Canon telezoom. Optical quality of thiis Sigma is excelent, so I would like to see the difference between this Sigma and Canon. I know, it is not quite fair to compare them, as tey are not both zooms, but anyway I would like to see the difference. Has anyone of you these lenses and can put here pictures taken at the same circumstances? Many thanks in advance.
