The a65 and nex7 with the alpa adapter use phase detect.
So annoying to not have fine tuning with fast lenses.
I see that now that I've had a chance to see some of the news posts. I'd love to hear the logical engineering reason for such a solution when you have a camera that normally works perfectly well using contrast detect AF (referring to the NEX).
Currently the NEX-7 appeals to me as an M back up, but I'd really like to see a decent range of primes from Sony for it. I guess the upcoming 24 will be nice, but more would be good.

A77 is larger than the D7000 and the K5. It's in fact almost as large as the E-5. The NEX-7 is obviously relatively compact, but that can't be said about the lenses, and even with this launch, there aren't very many to choose from. Right now, I'm relatively happy that I bought into m4/3.
The lenses will never be super compact due to the size of the sensor and all the AF and electronic aperture controls in the lenses. If one wants a 'large' sensor, AF and auto aperture control, one has to accept large lenses.
as far as i can see sony and zeiss do everything correct.
the NEX-7 is very sexy.
the only point is that it will cost the ~double of X100 with a ~24mm lens.
and i just saw a photo of this lens mounted on a nex-7.
- its a monster
Large-aperture wide-angle focal length lens that can open F value of 1.8 to fully enjoy the descriptive power of the Carl Zeiss lens. The latest optical design technology, and excellent correction of various aberrations, high sense of resolution can be obtained. The maximum magnification ratio at 0.25, has the ability to shoot high close. Also, due to internal focusing motor and the lens to achieve a smooth silent AF high, and it gives you to record movies. This high-quality exterior appearance with aluminum alloys.

NEX-7 looks f@... amazing. 2.5MP VF, 24MP, geeeze, really good.
Sony just basically smoked N & C.
If they stay focussed, who knows what happens...
It isn't 2.5MP, it is 2.5 Megadots! And that's only XGA.

just looked very quickly at the specs on the A77 between 470 and 530 shots on a single charge are we supposed to be impressed by that
Nope, but that's what you need to pay for EVF and SSS, a fair trade actually.

The key question in the slew of new products is IMHO: how good is the new high-end sensor? 23Mp for APS-C is, by far, a new density record. If Sony have managed that in conjunction with good IQ and noise performance, it will put massive pressure on competitors. I know that it is considered bad form to insist on pixel count, but it definitely matters in the market.
I think it won't be a problem. Looking at what Sony can do with their sensors recently, I'll be very surprised if their new sensor can't have very usable images at ISO 1600.

Still, Olympus and Panasonic manages to do that. The 4/3 sensor is smaller, but not that much smaller.
Actually, the Zeiss 24mm f:1.8 will be my street lens. Good news is that it weighs only 225g. That is a lot less than I feared when looking at its size
From Imaging-Resource:
Offering the chance for videographers to really unleash their creative side, the NEX-5N provides both aperture / shutter-priority and fully manual exposure for movie capture, not just stills.

Looking at the ISO 1600 test scene images from imaging-resource.com, they are just awful, much worse than ISO 6400 from the A900. Looks too bad to be true. Something may have been messed up, but I also checked one ISO 1250 image from dpreview, and the NR applied was excessive, like from a P&S. I wonder what this is about. Just extrapolating noise performance from current generation sensor into a higher pixel density would not indicate such a dramatic decrease in performance. I hope these samples are not representative.

NEX 7 looks great.It weights below 300g and is not much bigger than NEX3 or 5.Jay!Looking at rumored photos I was afraid that Sony will come out with some heavy monster.For sure Im gonna get one despite having 3 NEX bodies already
not had a good chance to look at teh A77 yet but from the quick scan thru the DPR stuff it does look pretty good
But I hope they have got over the EVF limitation when shooting at high speed that the previous ons had. I cant see why the hell when you generating the EVF from a seperat sensor chip (which is how I think they do it) you cant have a constant 'live' image in the VF .
And the one dissapointment is the buffer. 13 RAW frames is very small given the 12fps , which means a raw buffer of 1 second . most DSL's seem to be able to go for about 2 seconds in RAW (some a bit more) . It may not seem a big issue and how it acts when you hit the buffer stop plays a part but the larger the buffer the less likely you are to miss the action .
If they are aiming this at the higher end market (trying to take away from Canon 1D and nikon D3 ) in places like the sports market then buffer depth and battery capacity matter
are we supposed to be impressed by that
