I must have read wrong that the a6000 was all magnesium unlike the Nex 6 .How is the picture quality as in sharpness in the extreme corners and anything to compare it against.
I've been a Sony user for years. Currently have an a99, a57 and I just sold my old a850 to fund the a6000. I needed a compact travel cam for some business trips I have planned this year.
The sensor is great. I've used the NEX7 and the a77 and I'd say it's better than both at high-ish ISO levels.
Lens-wise, I've only used the kit lens and an old Minolta 45/2 (which was on my first SLR back in the mid-70's). The kit is rather good in good light, particularly between 24-40mm. Extreme corners are a bit soft, but it's rare that I don't crop a bit, so it's not a problem for me. As kit lenses go, it's much better than the 18-55 that sony DSLRs tend to come with. I particularly like the OSS and the silent focussing, which are very effective for video.
The OSPDAF is a little limited, as it only works in AF-C and only with wide or group/zone AF points. If you want a tighter target, it's CDAF. However, in practice I'm using AF-C/Wide pretty much all the time and it's very good at picking the right area to focus. Used this way, AF feels just like a DSLR.
I tried a Nex7 at a Sony event a couple of years ago and wasn't convinced. The IQ was great at low ISO's, but it got too grainy too quickly for my taste, plus the software interface and AF speed were horrible (coming from an SLT). The a6000 fixes all these issues, IMO.
