i think there is still a quintessential difference between the two color renditions of CCD and CMOS. Without doubt, CCD - particularly Kodak CCD - produces the best color. It may not be the most accurate and factual color, but it is the most "appealing" color. The only CMOS sensor which can come close is Foveon, which nonetheless has another very different color rendition - high micro contrast, vibrancy, and contrasty. Foveon is the digital equivalent of Kodachrome.
Therefore, I think it is right to say M9 still has more beautiful color. In fact, CMOS files are a bit hard to "cook" in the photoshop. I think vinceharus rightfully pointed out that the "workflow" will be very different. Not just to say EVF vs rangefinder experience, it also includes different approaches in post-processing. Most of the time, the hardest part to get right of color is skin tone. From the out-of-camera JPEGs I saw from A7/A7r, I think the skin tone is good, or at least good enough. I still cannot convert the RAW files with Adobe yet, so it is still a very preliminary conclusion. I can say I'm impressed by the color rendition of A7/ A7r. Even for the JPEGs, reducing shadows already produces very pop-up images. I like it.
With that said, it is not a perfect camera by any means. I don't think it is a good camera with wide angle M lenses. Dark corners, color-shift as best, smearing as worst. Performance will become even worse if the lens has a very ball-like rear element that is close to the sensor, namely, the biogon design. The incident angle is still too big for proper performance, even with micro lenses. It just won't work.
But if one uses 35mm lenses or above, the A7r will be quite a joy to use - very easy to focus, and super accurate even on 36mp resolution. I think some 28mm will perform well too. But I won't go wider than that.
Technology changed. In the film era, rangefinder, i.e. short-flange distance, is good for wide, or eve super wide lenses. Biogon design helped to produce distortion-free images, such as the SWC. But with the introduction of digital sensors, concept changed. For wide or super wide, it is safer to go with DSLR bodies or even medium format. After all, different technologies lead to different designs, which also brings different usage and preferences. |
