On the whole I am satisfied, but inspire me really can not the lens. For data sheet fetishists it is perfect: very high sharpness even at full aperture, and the lens is stopped it will be even better. Also CAs and flares are very well corrected. However, the AF is not really great. The precision can sometimes be desired (but on a level that I can accept) but he's just too slow. Even the old 35er Canon with the circular saw motor is at least not slow in my experience.
Worse, however, I find the bokeh. Probably due to the optimization of field blur circles in the background are very harsh, which acts very restless. The Samyang is here much better and I would prefer its appearance anytime, and also like to take the (in real-life situations usually completely uncritical) stronger Lensflares in purchasing.
So I have to say it's the best in the price range 1.4 35s, there was a fully automatic Samyang, I would definitely prefer however, even at the same price.
