    Every now and then i notice while shooting in Aperture priority with manual lenses the camera pops out a one-off of strange exposure image even though its ISO100 the noise seem quite high. Anyone have thoughts to the cause of this? i think it might have something to do with a combination of colors but who knows.
    At ISO100 the sky should have a much more even and or smooth color fade. What do you think? (please ignore the lens spots)

    Is this jpeg or raw? If its raw, then i have experienced it too. I researched it at the time and many people think it is related to sony's lossy raw formula vs a lossless output of others. They say missing information results in banding and non-smooth gradients.
    I don't like it, but it doesn't happen all the time and when it does, I can usually correct it. I do wish they had lossless raw, but not enough to use a different platform.

    Ah ok that's not actually noise but rather banding. Thanks for the reply.
    That image is from the in camera Jpeg. But sense you mentioned it, i went back and looked at the ARW file and sure enough the noise was there and much harsher than the jpeg.
