Re: OT: I'd be pretty ticked off if I'd spent this much for this kind of performance
Thanks Tim, for making it available. It opened for me just so. Darren, I doubt that you could find a camera and a system for that matter that were absolutely free of any kind of issue, or problem or something that would make one's life grievous in some manner. Just off top of my head - Nikon D800 were leaking light through the top LCD if I am not mistaken, Canon 1DMk3 had some firmware problems as well or was it also some light leak. Naturally, Pentax K-5 with its problematic sensor just when it started to sell and other problems (ask Paul Stenquist). On the less general note - my DA* 16-50/2.8 is very good optic, but it is soft towards the corners at wide zoom settings. I don't really like that. But I live with that. Ultimately, it seems to me now that Ricoh GXR won me over and I will be migrating to the A12 M-module buying one of those very wide lenses: Voigt 15/4.5 or 12/5.6 - I am not sure just yet which one for my wide angle. My plan is one of these two, 28 mm and 50 mm Ricoh modules (those are equivalent focal lengths, the real ones are 18 and 33 mm respectively) and one of the 50 mm lenses for portraiture. Galia wants now a small camera too, so that I may have to buy another body. Or may be I'd just buy M-K adapter and use my 50/1.2 for 50 mm. I expect to be met with this kind of problems if of smaller (cannot bring myself to use word "lesser" here) extent due to sensor being APS-C size.

Re: OT: I'd be pretty ticked off if I'd spent this much for this kind of performance
This will show you a similar thing: http://dl.dropbox.com/u/25268645/Skopar_28_calibrations.jpg That's the Voigtländer Color Skopar 28mm f/3.5 on the M9. The screen capture shows the raw imaging vs CornerFix corrected imaging in pairs as the lens is stepped from f/4 to f/16. Top two rows show in-camera corrections with two of the Leica lens correction settings, bottom row I've turn the corrections off. CornerFix cleans up the imaging issues nicely in all three cases.

I spent almost a year researching the M9 before plunking down 6+ big ones for it, so I knew what to expect. Which doesn't really prepare you for the reality of actually using your lenses on it anyway, but it's as good as you can get without having one in your hands. When you spend $80,000 and buy a medium format digital camera system, don't be surprised at how difficult it is to use and obtain top notch results with ... !!

Charles :: if you have trouble getting to the site, I can easily post you a couple of calibration tests from the Skopar lenses this evening. They're not quite as extreme as the Heliar 15 or 12 would be, but they show the same essence.

Creating an interchangeable camera than can work with MOST existing lenses and that can obtain excellent quality is amazing, something that people who understand digital imaging systems marvel at. The issue is the one that most of the SLR community pooh-poohs as being a non-issue: the PRIMARY difference between film and digital sensor as recording medium is the sensitivity to the direction of light falling on the sensor. Due to SLR mount registers and the fact that most DSLRs use a smaller format sensor, the issue is largely under control. The CV Heliar 15 and Heliar 12 lenses are two of the MOST difficult lenses to make work well with a digital sensor, due to both their extremely short focal length and the specific optical design they use. The primary nodal point is very close to the imaging plane, the worst case for a digital sensor, which causes the color shifting and vignetting you see. People willing to spend the money for a Leica M9 understand this if they have any sense, and they either choose lenses more appropriate for the camera or make use of other tools (CornerFix is one of them) that do the appropriate post-capture massaging of the raw data as required. Leica only supports their own lenses with the in-camera correction processing ... some of those corrections work well enough with the CV and Zeiss lenses, but in some cases they do not. (The Ricoh GXR M-mount camera unit, having been designed for an arbitrary range of lenses mostly not their own, AND with a smaller sensor, has in it a vignetting and color shift processor that works on the raw data and allows you to apply the appropriate corrections in camera. They are saved to both raw and JPEG files.) Put the Leica lenses on the M9 that Leica has created optimizations for, or use CornerFix, and the quality is breathtaking ... "medium format" in many respects. You can't get that by using just any old lens, designed for a different recording medium, on the camera. I have tested my lenses extensively with the M9 and the Ricoh GXR-M. I find that some of my favorites, like the Skopar 28 and 21, need almost no correction on the GXR-M but require that I use CornerFix on the M9. Yet once I pass them through a CornerFix optimization, the M9 exposures are just plain amazing in quality. Trade-offs ... it's inconvenient at least. But having seen what it can do, and appreciating it, much of what I once thought was excellent performance on the SLRs is only "satisfactory".
