    These are patents for Zeiss 24 f/1.8 and derivative designs. I don’t think we’ll ever see any alternative variants to the one released already. If Sony releases packages of patents like that – only one lens of these gets released. This one already has been.

    Full Frame defeats the purpose of the NEX line. Why would you want to mount heavy/bulky lenses on a small camera??

    Sony just doesn’t get it. Time to move up to M4/3.

      LOL. I needed a Friday laugh. Thanks.

      In case you were serious…

      1. Have a look at the RX1. Full frame and smaller than many m4/3s:

      2. The NEX lineup slaughters m4/3s for sensor IQ at the same price point with no appreciable increase in size or weight.

      3. Zeiss glass ftw.

        No, not Zeiss glass, Sony glass with Zeiss sticker.

      This is a joke, right? Move up to the mighty 4/3 sensors, you’re gonna be so happy!

      Just take a look at the sizes of the various M mount lenses by Leica, Zeiss, Voigtlander, etc.

        The lenses you mentioned DON’T have auto-focus or built-in image stablization. Feature that many people want … and that will add size and weight.

          There are people who want to use adapted mf lenses too and sony is strongly supporting them, if you have followed what’s been happening. Adapted lenses are much easier to use on these mirrorless cameras and especially on nex bodies. These are not the dark ages of photography… although you couldn’t tell by reading comments in sites like these.

          • loki989

            Exactly. And embrey doesn’t seem to even know what’s available on the NEX line at all. The latest NEX-3N weights in at 210g, with a sensor that beats all m4/3s cameras. Further, if the RX1 lens is any indication of what an e-mount FF would be, it’s going to be amazing. The dxomark score just announced was 33. That beats every lens on the market, period, in a very tiny package.

          • kuishinbou

            The NEX series cameras have had better image quality and depth of field control then M4/3 since they were introduced…the only benefit of m4/3 is lens selection, weather sealing, and in-body image stabilization. Personally, I prefer the style and image quality of Fuji x series cameras, but a full frame NEX with a full set of high quality lenses would be appealing…the only problems are the lack of high quality lenses and the cheap feel of the cameras – manual controls and better style please!

            As a person who had high hopes for the RX1, I can’t say I’m impressed by either its sensor or its lens. I sort of knew what to expect from the sensor because it was already there in the a99 and D600, etc. But it’s the lens that disappointed the most… it’s far from what I would call a premium lens.

            I have a ton of respect towards Sony for fitting it all in such a tiny package. I’m sure they did their best but the image quality matters a lot to me at the end of the day and the amount of CA shown by the RX1, even when stopped down, is not good… for me at least.

            DxOMark has gone a bit too far as of late with their over-simplify-everything philosophy. At first they did good with their sensor tests better than most other places but they draw far too many conclusions with no consideration for the test limitations. The lens tests are just rubbish… a complete joke. As I always say… you can’t dumb down multifaceted things like the performance of sensors and lenses to one single number and still always be right. They’re like a bunch of teenagers going through a magazine together, rating celebrities out of 10.

          • loki989

            So they put a full frame sensor, the exact same model shipping in top end SLR cameras into a _tiny_ body and you’re still not happy? I have to ask, what would it take to impress you? The same sensor as, say, the D800? Maybe the same one as the 645D? /facepalm

            You take the one weakness of the lens, low-to-moderate CA below f4 (yes, it drops way down at f4) and declare the lens is bunk? With resolution off the charts and CA you have to pixel peep to be annoyed with? /doublefacepalm

            I unfortunately don’t have the spare 3 grand or I’d buy one, and lots of prominent photogs, including Michael Reichmann over at LL agree it’s a winner. While I’m hot a huge fan of dxomark, your expectations and opinions are too far removed from reality to be insulting others.

            The RX1 has a fixed lens, and for the price the lens should be that much better, plenty of reports on the colors being rubbish as well. Because there’s no other like it, yes it’s an awesome little guy, but it could be so much more and we’re waiting for that. And as complaining of the price is ridiculous how about $500 for an add-on VF that’s just a box or 200+ for just a lens hood?? All the accessories command an insulting price, and all for a camera that has a fixed lens… while I’ll gladly pick up the X100s, but of course a lot cheaper and with a special hybrid VF

            “and lots of prominent photogs, including Michael Reichmann over at LL agree it’s a winner.”

            It doesn’t matter… really doesn’t matter what they think or what I think. So you shouldn’t take it personally when someone says they’re not satisfied with a camera you think the world of. If it works for you, then it’s a good camera… unfortunately for me, the RX1 isn’t quite there.

            “You take the one weakness of the lens, low-to-moderate CA below f4 (yes, it drops way down at f4) and declare the lens is bunk?”

            No, it sucks at f/5.6 too… that’s pretty bad even by APS-C kit zoom standards… forget fixed-lens, sensor to lens-optimised, conservative f/2 (not f/1.4) design, premium Zeiss-labeled prime standards.

            “With resolution off the charts and CA you have to pixel peep to be annoyed with?”

            I have a question for you… what’s your best lens? And what do you think is the best lens? We obviously have different standards… but do answer that question.

            “your expectations and opinions are too far removed from reality to be insulting others.”

            Most Nex bodies are all metal… never felt they were cheap. And I’ve use pretty heavy lenses on them than most people have:
            http://www.flickr.com/photos/genotypewriter/4856429147/

            Nex bodies might look cheap because people’s prejudices make them think anything that looks retro (like a Pen body) is also built better than modern stuff.

          • kuishinbou

            Perhaps cheap wasn’t the right choice of word, but I don’t like the design and feel of the cameras. I do like their innovation though…and, Sony may be the first to introduce a full frame mirrorless camera with AF and interchangeable lenses, which will be very interesting.

    • kuishinbou

      We must give credit to M4/3 for attracting other companies to make mirrorless cameras. However, there will be no need for such a small sensor once there are larger sensor mirrorless cameras with a full range of lenses in the near future. Fuji is almost there now – by the end of the year – and if Sony can pull off the FF NEX (hopefully they design it better) with some quality glass, it would be pointless to buy a M4/3 camera. The only advantage M4/3 has right now is a full set of quality lenses. The image quality in the Fuji X-series cameras and the Sony NEX series cameras is superior to any M4/3 camera…

    nex FF and good bye nikon and canon ^_^ are doomed

    • http://genotypewritings.blogspot.com/ genotypewriter

      I’ll be the first in line when this camera comes out but if your argument’s right, why is there still such a thing as FourThirds/microFourThirds?
