哪位能测评下徕卡新M与5D3、1DX或D800E、D3X对比，以化解想买M的人的困惑，谢谢。

There has been much discussion about the relative benefits of CCD and CMOS sensors on the internet forums. I wish I could get a real handle on the differences, but I’m bound to admit that, to my eyes at least, it’s much more to do with how the firmware is adapted to take advantage of colour or noise.

My observations on the image quality of the new camera are therefore very much subjective - of course I’ve done controlled comparisons between the M9 and the new M at base ISO and also at higher ISO, they’ve helped me to come to my conclusion, but they aren’t useful for publishing. My feeling is that the new camera has about 1.1/2 stop improvement in high ISO noise performance (so that 1250 ISO was the most I would happily use on the M9, and 3200 is fine on the new M). As far as colour is concerned, I think  that at base ISO the M is a little richer than the M9 (with a fair amount more dynamic range). At higher ISO I think it’s altogether better, especially skin tones, which I always found unkind on the M9 above 1000 ISO. Leica have made a real effort with the jpg files, which are much better than those of the M9, and you can use the settings to show up on the LCD (even if you are only shooting DNG).  I’ve processed the DNG files in Capture One, Lightroom and Apple Aperture, (none of which have proper colour profiles yet). My instinct is that they are noticeably more malleable than those of the M9; they take a lot of bashing!. I’ve also used Silver Efex-pro for black and white conversions, which have worked out pretty well.
