    Sure, Michiel! Including its 2.5Kg weight and its 6000$+ cost, no doubt?

    Michiel: Nice composition, perspective and angles, particularly as for # 1. So the possible cliché is nicely redressed, to my taste.

    Thanks, philber! I've been using the NEX-7 with various M-mount lenses since May last year, and it has been an eye-opener with more than one respect. I've re-discovered B&W (more or less dormant since my darkroom days), and I must say that I enjoy the process of working with purely manual lenses enormously. I've also spent much more time photographing landscapes. Previously, my focus was on wildlife (mostly birds). The small size and weight of my NEX-kit enables me to do things effortlessly that were a pain or even unthinkable previously. The image quality the NEX-7 delivers in combination with these lenses is a very welcome 'bonus', of course. I've printed the above images at a size of 24x36", and I continue to be amazed by the resulting level of detail...

    Best,

    Ron

    As you probably know, the corner problems on the NEX-7 are due to the characteristics of the sensor's microlens array, which is not designed for use with non-retrofocus WA lenses of quasi-symmetrical design (i.e. those that have a rear element that sits close to the sensor, such as is the case with all Zeiss Biogons and many other M-mount WA lenses). These problems manifest themselves in two ways:

    - Purple color shift and vignetting in the corners
    - Loss of detail and sharpness in the corners

    The former can be corrected fairly effectively, the latter only to a very limited extent.

    To deal with vignetting and color shift, I used to use Sandy McGuffog's excellent CornerFix application, which works very well. However, it doesn't integrate with Lightroom very smoothly, so I started looking for alternatives. A few months ago, Adobe released the first beta version of its DNG Flat Field Plug-in, which makes flat field corrections within Lightroom a much less painful experience. It can be downloaded here: Download Plug-ins for Adobe Photoshop Lightroom - Adobe Labs

    Here some pros and cons of the two products:

    CornerFix
    Pros: works with any DNG-based workflow
    Cons: requires DNGs, no direct integration with Lightroom (requiring exporting and importing of DNGs), alters actual image data of the DNGs

    Adobe DNG Flat Field Plug-in
    Pros: integrates well with Lightroom, doesn't alter image data (employing Adobe-proprietary op-codes instead)
    Cons: requires DNGs, only useable with Adobe products (due to proprietary op-codes), can be a bit buggy (producing seemingly spurious error messages - but it's in beta, so I guess that's OK)

    HTH,

    Ron

    The APO-TELYT results in approx. 200mm focal length in full-frame terms. The above shot is actually un-cropped. I do have the Hawk's helicoid adapter as well, but I don't use it very often. This is for two reasons:

    1.) It is not very mechanically rigid, particularly when extended. This is not ideal, particularly when using longer lenses and/or slow shutter speeds (most of my images are taken with the camera on a tripod).

    2.) Mine doesn't allow focussing to infinity on most of my lenses, which means it is not my default adapter for M-lenses (I use a Voigtländer VM-adapter for this purpose).

    That said, I have used it a bit for macro-like work and for portraits, but because it's not always on the camera, it doesn't get used much. I should really make an effort to use it more often...

    BTW: for close-focus work, particularly with longer/heavier lenses, I use the Kenko extension tubes for E-mount. They are much more rigid than the Hawk's adapter, and they carry the added benefit of providing all electrical connection to E-mount lenses. Despite their mechanical robustness, they are actually surprisingly light-weight.

    Best,

    Ron

    Re: Fun with NEX-7

    Good read, Ron! And nice work.

    Yesterday I went out with three cameras on the same subject. I have to regret to say it but the NEX-7 files, although they are very flexibel in PP, are in the third place. (compared to Ricoh GXR and DP2m)
    But I love the camera in use and it is a great adapter for all kinds of Alt lenses.
    (And the files are good enough)

    Many thanks! I like many of your images. I have a soft spot for ships, boats (the older the better) and the sea. Unfortunately, we don't have much of that around here...

    Interesting! I agree, NEX RAWs are wonderfully malleable in post - much more so than those of the Canon 5DII.

    Besides Sony NEX, the only alternative use for M-mount lenses I've seriously tried is MFT (with a Panasonic GX-1 - this was actually before I started using the NEX-7). While the results were definitely OK, they were nowhere near the image quality I get with the NEX-7. Considering the differences in resolution and sensor size, this is no surprise, I guess.

    Are you using the Mount A12 module on the GXR? I've always found the concept of the GXR very interesting, but have never had the chance to try one...

    I have just recently started using an NEX-6, mainly because I was looking for a sensor that has better characteristics for use with M-mount WA lenses. I am planning to use it as a complement to the NEX-7, not as a replacement. I haven't worked much with it yet, but there's definitely a big difference with regard to image quality in the corners when using WA lenses compared to the NEX-7. The color shifts are almost gone, and the loss in detail and sharpness is much less pronounced.

    I was also considering the Fuji XE-1, but after processing some sample RAWs in Lightroom, I decided against it. LR/ACR definitely don't process these files optimally at this point, and out-of-camera JPEGs provide much more detail than RAWs processed in LR. Quite a shame, really.

    I'm thinking of renting a Leica M once it becomes available. I'm very curious how it will compare to the NEX-7 and how my M-mount lenses draw in the peripheral regions on a FF sensor. But the results would have to be nothing short of amazing to justify the price of the camera...

    Since I do a fair bit of large-format printing, I very much like the high-res files of the NEX-7. I would only replace it with a camera that features a sensor with 20MP or more (and featuring noticeably higher IQ, of course). I would really like to see a full-frame NEX, but I have my doubt's that will ever happen. IMO, Zeiss should work with SONY on a digital IKON with the same sensor used in the RX-1. That would be exciting!

    The body, which is very nice and sturdy, is so cheap but the M mount module is not so, around €500,-
    But no corner problems, no loss on sharpness. It has a Sony sensor as well but no AA filter. The files are rather sharp by themselves. For example; The NEX-7 files sharpness can be turned up to around 90 in ACR and the ones from the Ricoh should never go above 55 in my opinion.

    Same here.....

    I don't know how big you print but I think 60 x 80 cm prints will still be very exeptable from the Ricoh. BTW the Sigma DP2M is very good for B&W as well.
    You would be surprised/shocked by the amount of sharpness.....

    Yes, or a Foveon mirrorles FF camera from Sony, Sigma or Ricoh.....I don't really care..

    Nice picture, Ron! Like you, sometimes I correct 35mm pictures and sometimes I don't. But that still doesn't tell me what magic you perform on your ZM 21, which turns me green with envy. Fell free to replay in PM if you want.

    Hi philber! Did you see this post?

    http://www.getdpi.com/forum/480558-post1279.html

    There, I explain how I apply corrections. The 'Window to the Sea' image was cropped somewhat, so you don't see the original corners. Other than that, no magic

    Re: Fun with NEX-7

    I should add, though, that one of the reasons (the main reason, actually) for my recent purchase of the NEX-6 was the disappointing corner performance of the Biogon 21 and the Heliar 15 on the NEX-7. Corner performance is much better with these lenses on tne NEX-6 compared to the NEX-7.

    Re: Fun with NEX-7

    @philber: maybe I should ask what you consider 'magical' about the image. Are you unhappy with the performance of your ZM 21? Perhaps you could share a sample image to illustrate?

    Generally speaking, the ZM 21 is a very good lens (it should be, considering its price), being very sharp corner-to-corner (on full-frame) from f/5.6 on, demonstrating very low distortion and quite good flare resistance (the latter thanks to high-quality coatings). Sean Reid has a good review on his site (subscription required).

    Edit: I should clarify that I'm speaking of the 21mm f/2.8, not the f/4.5 C Biogon. Which one do you have?

    Thanks Ron!

    I have actually tree adapters. A cheap Pixco wich I bought for the connected tripod mount for my Zeiss Vario Sonnar lenses which have no tripod mount collar.
    The tripod connection started wobbling in no time so I took it off but then it wouldn't hold my 85 Planar which has a slightly worn-ou mount.

    After that I started to use a C/Y to Leica on top of a Leica to NEX adapter that worked surprisingly well. Looks like Leica adapters are quiet precise. No name.

    Now I use a Tilt C/Y to NEX adapter which is good. I bought it because I did some nice things with tilting with OM lenses on M4/3. But now I am mainly using it as a regular adapter. It is well made. Look for Tilt C/Y to NEX on Ebay. It is a no name adapter. There are two types. I have the all black one.

    Re: Fun with NEX-7

    Many thanks for the info, Michiel! To me, the Zeiss C/Y 85/1.4 and the 180/2.8 look most interesting, considering the lenses I already have. Good to know what adapters work well!

    Here another image made with the APO-TELYT-M. This is the kind of work I usually use my DSLR-rig for, but I wanted to see how the NEX+APO-TELYT combo would work in such a setting...

    Re: Fun with NEX-7

    One of the reasons I got into landscape photography is panoramas. Below an example from the Swiss Alps. Sorry that it's a bit small. The original is more than 15'000 pixels wide. I find that the 35mm C Biogon is very suitable for this kind of work.



    And here a 100% crop:

    Re: Fun with NEX-7

    Actually I don't own a ZM 21, Ron, I tried the excellent ZM 25 and was disappointed with corner performance even on NEX 5N, and I knew it would be worse on the 7. So I switched to Leica for the great Elmar 24mm f:3.8 instead, which can be corrected easily in CornerFix. Had I known that the ZM 21 could be corrected, I might have chosen otherwise. And thanks for the info!

    Re: Fun with NEX-7

    The vignetting and the color shift can be corrected no matter what lens it is, as I'm sure you know. Both CornerFix and the Adobe DNG Flat Field Plug-in do a good job at this. The loss of detail and sharpness is another matter. It can be alleviated to some extend by local sharpening, but that's about all that can be done (as far as I know).

    You may notice that the 'Window to the Sea' doesn't have subject matter with fine details in the corners, so the corner artifacts don't show. I wouldn't say that the Biogon 21 doesn't suffer from them when used with the NEX-7 - far from it. But in many cases, it simply isn't much of a problem, as long as the color shift is corrected.

    My first M-mount lens was the Heliar 15mm, and I decided to go further down this route (i.e. with other WA-lenses of quasi-symmetrical design), betting on the possibility that at some point in the not-so-distant future, a camera body will be available that handles these lenses well. Time will tell if my bet turns out to be a winner. In the meantime, I decided to go for the NEX-7. My opinion is that lenses are the lasting investment, not the sensors behind it. I hope I invested well...

    Philber, when you say that you 'switched to Leica', are you speaking only of lenses, or camera bodies as well?

    Re: Fun with NEX-7

    Hi Ron! Great pictures! The panorama looks great. Nice to see the ZM35C getting some use on the Nex-7, I think people have been scared of that combo. Though probably the "worst" would be the ZM21C (or the Contax G 21).

    The recent Leica lens designs do lead to, IME, generally better corner detail than the ZM Biogons do with the Nex-7. But you do have to pay for it.

    I've found that generally, I get better results with the 21 Super-Elmar using Cornerfix. For the 28 Elmarit (latest), I mostly use DNG Flat Field, but sometimes I get better results using Cornerfix. Though, I also have been trying to get away with just a single reference picture (f/2.8) with that lens.

    Re: Fun with NEX-7

    My analysis is fairly close to yours Ron. The M-mount is now pretty much an open platform, with 6 manufacturers providing camera bodies compatible with it. That generates faster progress than the Canikon lines, where high-end models get replaced only every 3 years +.
    So, once I decided to go M-mount, considering my lack of lust for an M9, the NEX line was an obvious port of call.
    On my 5, then my F3, then my 5N, I loved the results with ZM lenses. Then I tried the Elmar 24, and was hooked. I bought it, and a Summilux 50, and rarely use my ZM 18 and 35 f:2.0. That is partly due to my weakness in PP, because the Leica lenses require less of it than the ZMs IMHO, and I am trying to correct that so that I can use both lens brands equally to my satisfaction.
    What next? I will obviously try a Leica M, because the inclusion of LiveView makes a big difference to me. Otherwise, I shall wait for the platform to get better, whether it is at the hands of Sony, Ricoh or anybody else...

    Re: Fun with NEX-7

    Thanks for your feedback, Taylor and philber! One lens I've been curious about is the Leica 16-18-21mm WATE. Have any of you tried this on NEX? If so, what are your findings? I think this could be an excellent choice when you can only bring one lens.
