super se - only disturbs the autofukus

the images obtained with this lens are really great. especially sharpness and bokeh convince. but on this issue is indeed here quite a bit.
the processing is great. as has been mentioned here that the objective in focus extends quite far: Yes that's true. the length doubles almost fully extended. However, it should be mentioned that this is not noticeable unless you plan the supplied lens hood area. and as these from the beginning was with me at the top, I could see at all that only after about half a year ... ;-)
so we have arrived at the point of criticism: the focus. he is absolutely fail (had but inside the camera with my K5 correct -0.4) but really noisy. even louder than other old Pentax lenses like the 50mm f 1.7. particularly when the focus is not the same place and the whole focus range is searched. Luckily, you can intervene manually and the objective a little helping hand. This function is also at the noise and duration really appropriate and necessary. for portraits and weddings, I really feel that for too loud. So always be ready to focus preset a bit, if you do not everyone's attention and its camera will go. makes manual focusing but really fun. it can be set pretty much everything. he's gone long, but for my taste, the resistance should be a bit bigger. Still, I find that it is similar to manually adjust well as most m-42 objective that I have in use otherwise.

briefly to verareitung: the lens twice now including body from approx 1m fell off me (both times ended up on the objective and what can I say. everything still works fine!

So if EH also like to focus time manually - or at least is willing to manually intervene in the process, which can be the lens highly recommend. the results and the processing are top.
Who but the faint of 18-135 or as Canon USM is used, which should be the objective, I think only times the merchants of his acquaintance watch and consider whether it is not too loud to him.
I will objectively at least not easily give up, even if I should change in order kb Format Canon again. the K-5 and this objective are your money absolute value in the combination
