I have been a little disappointed with the optic selection for my travel camera (the A6000). I love the A6000, it's not my 5D III or 1D IV, but it's IQ is very good and it's so much less to carry around for travel. The 70-200mm OSS has me very impressed, even against my 70-200mm 2.8L IS mk II Canon.
I've used several fast primes (Canon FD 50mm 1.2 L and more) with the A6000, just received this 35mm 1.8 OSS and I am blown away with it's sharpness and contrast at 1.8. Very much better than all the 1.2 primes I've tried with the A6000 and the oly m43 cameras.
Bravo Sony! Great lens. I wish that I felt this good about my Zeiss 16-70mm. It's a good lens, but this 35mm will live on my camera.
