Gives bad?

Very good goal, very light and with superb image quality. For those who hesitate between a 35 mm and 50 mm APS-C sensor, take the 35 mm without hesitation, because the 50mm is really too "zoom" the 35 mm is already within limit if you want a view complex. By cons, after 2 months of use, reference to Sony SAV (at my expense) because the pictures were overexposed (see white) as soon as you shut a little diaphragm. Given that the objective is neither fell nor did left my SLR, it's a bit annoying. The problem was solved by changing parts service.
