Received in perfect condition, I hasten to mount it on my 5D Mark II for the test, the stake is great with the fast and accurate AF (even in low light). 1.8 The very significant opening, optical compact and looks quite solid, long-term view ... Very happy with my purchase special value! I advise no problem.
After nearly two years of use: Solid, always like new despite heavy use. The sting and the depth of field at full aperture are still very remarkable (beautiful bokeh) I do not go out without it has become indispensable, especially for portrait! I recommend 100% for amateur and pro!
