Have the lens are in use for several weeks and have to say I am more than thrilled. After initial difficulties interfere with focus I have to say it does not take long to get a feel for it and has developed "almost" every photo is good. Use it on a Sony a77. Thanks Focus Peaking and 100% view it's super easy quiet objects reflect well. It becomes difficult with moving people or animals. As at f1.4 the sharpness level is already very low one does not always equal because focus especially if the object very well located in front of the lens. Chromatic aberrations occur particularly at f1.4. But through appropriate software that is corrected very quickly and therefore not a negative point. The lens is built very heavy and high quality. The focus ring has a long way to focus, sodas you can focus very precisely. (Especially good because you can move the focal plane when shooting quiet and smooth.)
1 star I draw from it only because the sun visor is absolutely useless. You Wobble and locks not really so that they fall off quickly. Too bad because the lens especially for because price worth recommending (to a Sony) is.
