First unpack the room is beautiful, very well finished, she commands respect. The case is that of the SMC DA * series, with Velcro closure tab. Then the sun visor is massive and not dished which surprised me, probably specific. The fixing ring is accessible on foot from the well-placed left hand if you are right handed. At the same use without foot (Pentax K5), you can take clear shots without forcing the speed which pleasantly surprised me. Where I was amazed, it's the quality of the AF, speed its high accuracy and its silence. Photographs taken exhibit beautiful bokeh, almost intoxicating, very poetic. The sharpness is excellent, maybe a notch below a 2.8 focal length (to verify). Finally the handling is rather easy because it is not TV really heavy which increases photographic enjoyment.
I recommend it for wildlife photography even under conditions of medium light. For sport, you have to test, I try to complete my review once past some auto racing shooter ...
