HaHa! I doubt Sony is interested in making a FF NEX to act as a digital back for you.
Lenses are where the $$$ is.
That is why I don't think Sony would make a camera system where Zeiss will sell the lenses under their name only, unless Zeiss pays some per lens licensing fee to Sony.

Sure, but Sony would love to be the first on the market to do something, even if it doesn't ultimately work
Mirrorless being a digital back for alt lenses is an unavoidable consequence, no matter the sensor size.
So I believe that Sony will make the first FF mirrorless, even if just to prove they can do it.
We shall see since there is no concrete info to support either way (though the FF camcorder does give a strong hint). Nonetheless, it's just a matter of time.

the mount will work fine, the lenses just won't be that small if they are to perform well and autofocus. rangefinder wides will still be able to be mounted, they just will have poor corner performance.

I think it's the sensor technology that has to, and will improve.
Already on the Ricoh GXR I have no problem with any of the ZM lenses, no color shift whatsoever, even with lenses that go deep inside the mount like the 25/2.8 and 18/4. I'm sure the angle of incidence is greater than 20 degrees. Of course it is not FF, but all other APS sized cameras suffer from the color shift, even the Nex 5. So I have no doubt that a FF sensor fully compatible with extreme incidence angles is very possible, perhaps already exists (M10?) and most probably made by Sony
As much as I hope for an FF NEX, I am remaining skeptical.
SONY just as Canikon and others release photo products for Japanese market first hand. They never listened to foreign photographers and never will.
What would push them is probably Zeiss or some other non-Japanese company releasing and affordable mirrorless FF camera.

If the M10 uses a Sony sensor that's more compatible, I suspect we will see a number of short flange, FF cameras...hopefully including a Zeiss Ikon D.In this case I don't see how M10 could sell well.
If I have a choice and can get a mirrorless FF camera to put my M glass on, I would never buy an M10. No way.
The only reason to get it for me is the FF sensor. I think I'll wait either way, even if the mysterious NEX is not FF.
You're probably right, a FF mirrorless NEX is coming, the only question - now or in 2013?
I think there must be some connection - Zeiss mystery ZM lens, Zeiss new mirrorless line, unknown "pro" NEX....
BTW M10 has to be really exceptional. There is way too much competition now and if they make
another lowrez LCD joke or anything of this nature, they'll get absolutely smashed.
Also they really need to start paying attention, M lenses are widely available today, any lens you want
you can get today. Their Hermes editions based business model has to change.......Show more →
Funny how, despite the endless Leica bashing, the company is more profitable than Sony today and has been for several years.
"I won't buy an m10, but wait."
A courageous stance which happens to save you about 5k.
I'm on the same track but I don't fool myself into thinking its for any other reason than money.
I'd LOVE to try an M10, and would love to own an m9 now. But, for now, and the foreseeable future, they are out of my league.
3k for FF nex? That's a no brainer, unless it can't handle the M wides--which the first gen prolly won't.

It is also quite possible that neither the VG-900 or any future "FF-NEX" are fully 36x24mm - but slightly less? Just a mm or two in outer radiuses would make a world of difference. In the video camera this is almost certainly the case. The active area on the sensor they call "FF" will be more like 33.0x18.5mm for a 16:9 digital sensor- this would comply perfectly with the old film based frame standards. I wouldn't see that as a problem in the E-mount. It would be tight, but not impossible.

Certainly.
At the average pixel densities we're at today, the angles are a problem - IF nothing changes. There are several different strategies being tried (and they're well past beta-production stages) that minimizes corner smear due to incident angles. One of them (and the most obvious one!) :-) is to minimize the amount of coverglass thickness needed in front of the sensor surface. You can strip about 40-50% of the filter package thickness jus by using better materials.

Very thin cover glass and offset micro lenses. They don't have to take any lenses into account other than their own, so I guess they figured out the best compromise for the offset, which might be very different for a camera which has mostly tele centric lenses, like the NEX system.

And of course at Leica prices they can afford to use more expensive materials for the filter pack/cover glass.
A FF P&S? for $2800? Not quite sure what the market size is for that. Makes me think they wanted a switchable lens system, but could get all the issues worked out so they launched a fixed lens version instead.
Good for them pushing the edge of the envelope. Hope that it is just an opening salvo towards Leica and Fuji and gets Nikon and Canon thinking outside the mirror box for high performance systems.

Seems like I recall theSuede once saying that Leica actually uses pretty pedestrian/ low quality materials for the filter pack. What Leica does rely on is a lot of software correction for their wides.

IIRC that was the issue with the M8, the M9 was a different story mostly due to their experience with the M8 and its filtration issues.

theSuede was saying that about the M9, although it is better than the M8.
