I am grateful to have received a set of five M240 raw images that are similar to the ones that I used to compare the shadow noise and push color shifts of my M240 and the RX1 in this post.
While not exactly the same as the images from my M240, these new images exhibit a green color shift in the pushed images that becomes more extreme as the ISO falls and the amount of push increases.
I now believe that the color shifts I’ve been observing are not the result of my having a defective camera, but rather something inherent to the design. There is another thing to check, though. If there were an error in the Adobe camera profile for the M240, I’d see similar results with any M240, even if the camera itself is fine. I don’t think that’s the case, because I’ve observed anomalous noise floor versus ISO behavior with the M240 using RawDigger only, but it’s something I need to check before I point my finger at the M240’s design.
