The vice computing ducks on KB focal length of about 36 mm the glass to a highly universally applicable (not happen to have high-end cameras with fixed lens, being a focal length of about 35 mm), on the other hand inspired by extreme sharpness right into the corners, great colors, a hell Bokeh, fast AF (the AF phase of Alpha 6000 and NEX-6 is of course supported), virtually nonexistent distortion and a first-class feel (it is made entirely of metal, even the lens hood). Especially the 24 MP sensor the Alpha 6000 needs high-quality "food" in order to fully exploit its strength can detail, for the glass is ideal (but does of course at a NEX-6, etc. a good figure). Could not be better (at least for now), I would claim.
A small drawback is the lack of OSS, which would make the lens completely for "night vision goggles". Too bad, but to cope. Annoyingly, there is the - as with the Zeiss 16-70 / 4 - again only stuck serial number. When a theft is so little chance of his lens ever again.
And yes, the lens is already outrageously expensive, especially if you there in relation to - (the even comes for less than 300 euros with OSS!) Also prime sigmoid colon or the Sony 50 / 1.8 sets - visual and tactile. But this price / performance winner is now time exceptions that prove the rule: For a prime lens with high light intensity you pay a lot of money, even with other manufacturers, but can at least console themselves that the loss of money only briefly hurt doing, the acquired goods but for decades with every use prepares sinister joy.
Therefore: Buying this lens when it has an APS-C E-mount camera and somehow "scrape together" the money can. You will not regret it, it really is worth every penny.
