    NEX-7 test images up on Imaging Resource - WOW!

    There's a full suite of test images up on Imaging Resource and all I can say is WOW! These compare well to the Canon 5D Mark II, the Nikon D3X and by quite a bit the Pentax K5. At ISO 6400 the NEX-7 is nearly as good as the D3X.

    I can't re-post the images here due to copyright, but you can visit there and use their Comparometerô to check for yourself.

    Do you mean d3s instead of d3x? D3x at 6400 isn't that great I remember reading. They looks pretty good but AF is more of my issue. On the other hand, the Nex 7 is aps-c while the d3x is FX...so it is definitely not bad! I guess it is pretty good actually

    It depends if you're pixel peeping or doing a practical relevant comparison.

    At 1:1 on the screen the d3s is a lot better than the d3x.

    However printed at the same subject magnification the difference is not as big as many people would want to make us believe.

    So if the Nex 7 can repeat that with a smaller sensor it's indeed pretty darn good.

    Well, sure...practical vs. pixel peeping. It depends on one's mindset...I still shoot, on occasions, my d70. It isn't all that different printed 8x10 at, say, 400 ISO than compared with a d700. The photographer matters much more

    Obviously, I was in the "peeping" mindset on my first post.

    Re: NEX-7 test images up on Imaging Resource - WOW!

    Thanks for the heads up on this Brad!

    The 6400 is less interest for me than say 1600 is because the loss of detail is still too great ( at least with these samples processed the way they were) ... however 1600 seems really quite good, and 3200 usable in a pinch. Remains to be seen what real world results are in crappier light where higher ISO comes into practical play.

    My primary interest is use of this camera with the faster Leica M lenses @ 1600/3200. Combined with focus peaking, and real time review of WB, and all that, this could well be the camera to extend the usefulness of M lenses. My NEX-5 already does that to a much smaller degree but still can't compare to the M9 ... however, at 24 meg and a real viewfinder, that may change and bring the utilitarian ability of the Sony closer as a companion to the M9.

    Here's hoping!

    At any rate I have one on pre-order with Robert. Can't wait to slap the 0.95 on this thing!

    This is very encouraging!

    Finally finished selling off old gear, so I'm ready to buy as soon as my number is called on Robert's list!

    Marc, have you seen this page with real world samples (shot with a preproduction prototype of the camera !)

    None of the images of the mannekin manage to differentiate strands of hair particularly well. Anything over ISO 100 -- 200 and up -- has noticeably smudgy spots like detail was removed by excess noise reduction. Those would definitely show in even a small print like 11x17. Meh.

    The real test will be RAW files. OOC JPEGS are for Ken Rockwell. Sony's NR algorithms are notoriously strong.

    Re: NEX-7 test images up on Imaging Resource - WOW!

    Couldn't agree with you more, Jan. I looked at the 400 iso sample and it looks like it was dipped in plastic. Then I used the comparometer and compared 400 iso files to those from the Canon 7D and 5DII and the Canon files had less noise in shadows and cleaner detail in the green fabric of the mannequin's dress. Some serious detail smudging going on with the Sony files... My DMR is significantly cleaner than this at 400 iso and under, and though we're talking 24 vs 10 megapixels I can't see this as progress when compared to the DMR's six year old technology.

    Absolutely Carlos - I can't even be bothered to look. When it's RAW files from production firmware then I'll have a look (but probably only at the shots I've taken!)

    +1.

    Plus, at 24 meg. which lenses you use will also be revealing. I sure am not getting this puppy to use the kit lens on it

    I ordered the body only + Zeiss 24mm f/1.8. The kit lens never crossed my mind. However, most gadget sites (and Ken Rockwell) will base their "in-depth reviews" solely on the bundled lens. You would think Sony (and any other camera maker) would know this and make the kit lens worthy of the body it is bundled on instead a tease for you to buy better glass.

    Hi

    does the different DOF with fullframe of M9 vs. APS-C of NEX5/7 with the same lens does not disturb you?

    I shoot with a 50/0.95 ... what DOF?

    Hi

    no, I meant it differently. Let's assume you only have a Leica 35/1.4 and a 50/1.4.

    If you use i.e. the 35/1.4 lens on a NEX7, you would end up in a kind of a similar crop, but a bigger DOF then the same photo made with the 50/1.4 mm lens on the M9. But you do not want to go more "tele" in that situation for other reasons.

    Would that not bother you? With APS-C I find the background often too much distracting compared to FF. I have often situations, where I can not choose another background or another distance to the subject.

    Yes, I understand the concept. I currently have M9s and a NEX5. Given the same distance to subject the DOF is the same, it is just that the FOV is smaller with a crop frame. When the FOV is the same, then the DOF is greater with a crop frame because you have to move back to equal the FOV of a FF camera. The further you move back, the greater the DOF at any given f stop.

    Another way of looking at it is with a 50mm f/0.95 at the same distance to subject, it's like the FOV of a 75/0.95.

    I'm not a fan of crop frame cameras of any type, but the NEX cameras are a bit unique in size and features which make it attractive for use with M lenses ... ease of focusing, tilt screen and a better screen than the M9, and live view. A nice supplement or less expensive back-up to a M9, but most certainly not a replacement ... at least not for me.

    . . . . I think the kit lens is rather bad-mouthed, I gave it a good going over, and I thought it was pretty good - added to which, there are times when a small camera with a kit zoom just hits the spot - sure, the quality isn't as good, but sometimes the best is the enemy of the good. . . . and it's amazing what stopping down a little will do.

    . . . . For a lightweight walkabout kit the NEX7 and zoom should be fine - even if it's not it's main purpose.

    We've just spent a few days in Palermo, and I was using an M9 . . and the A77 with the much criticised 16-80 SZ lens - I've got plenty of worthwhile shots with that combination that I simply would have missed with the M9 (mostly because of close focus and long distance, nothing to do with the capabilities of the M9).

    For me there's a definite use for small, all purpose zooms, but certainly not for everything.

    As for making them better quality - wouldn't it be nice, but I think that will simply make them bigger.

    Re: NEX-7 test images up on Imaging Resource - WOW!

    Yeah Jono, I also have both the AF kit lenses, and they most certainly do have their place ... I've used the 16mm as a pocket camera that actually fits in a pocket when in social situations like my wife's company parties. If I brought something more Pro looking, I just end up having to shoot stuff because people there know I'm a professional photographer ... instead of enjoying the party.

    I need to at LEAST have something in hand that's better than my wife's iPhone 4 ... which she is pretty darned good at using

    The difference doesn't bother me all that much. It really only becomes an issue when working at extremes. Shooting a 35mm f1.4 on NEX is roughly equivalent to a 50mm f2 on a 135 sensor, and I'm not always a strictly shallow DOF type shooter.

    I ordered the NEX-7 with the kit zoom simply so that I have stabilized video option for my generic home movies of the family. Granted, the kit zoom is actually capable of pretty high resolution in the middle 2/3rds of the frame.

    I ordered it with the kit zoom, in addition to the body only option, because I don't know which version will ship first lol

    LOL - same instructions my dealer has.....whichever ships first. I have the kit zoom in silver already. The price of the kit is only $100 more so not a huge deal.

    Have you tried the camera on the iPhone 4s yet? - it really is extremely good - A4 prints sharp right into the corners - I haven't tried an A3 yet - but I suspect that'll be useable as well.

    . . . . . . and I've used the 16mm as well, it's fine for pocketable, and you can make the corners sharp(ish) at f8 as well.

    I do wish Apple would hurry up with RAW support on the A77 though - but perhaps it'd be better to wait so that they can do the NEX7 at the same time

    all the best
