tested once briefly

have the part via amazon.com sourced from the United States (Samyang, the rokinon they did not export, anyway, made in Korea, is all the same, just not the word), and made first steps, not so easy a sharp photo to shoot, which focus (it use to the NEX-6) is easy, but the motion blur ... use monopod or tripod is called for, out of hand is more a matter of luck. so from 1/500 It's getting what. The pictures are a little less contrast (reflex lens) but not too bad (my opinion, and what has to mean already, am not a pro). I had a lot of time but not for a few more examples from the window it was enough, 2 images plus a per crop. I love the lens (yet) of fun and I will test times in the field, because I find the time to do so, then there's perhaps even an update.

who does not have so much to look at the hard-earned, the can's consider, with limited budget I would not buy, that's such a thing with cost per photo, this is never a immerdrauf, rather a rare top lens.
