Sigma 70-200mm f/2.8 EX DG OS HSM

Pros: Nothing

Cons: At F2.8 unusable for astronomical photography and photography in general, everything improves to F 5.6

Opinion: I have the lens in question for about a year, I tried it on Canon 1300D finding it bad as a construction, at F 2.8 unusable with deformations to the edges and a crazy vignette. I spoke to Mamiya Trading, who told me it's built like this and they can't replace me. Here's the answer: Good morning Mr. Ribaudo Sigma after seeing the images wrote that if there is a bright object in the center of the frame and being the optics is old-fashioned, both things can cause the situation you encountered. Finally Sigma Japan has recognized the manufacturing defect and next week I should receive it replaced, hopefully well.
