    Intermittent Sensor problem

    On occasions I am getting a blue and red vertical line on a blue sky background. I have tried different lenses and the "problem" is still there when shooting raw. Other than "sky" shots there is no problem. Is this a sensor problem? I am attaching a jpg which shows this to the left of the mast. Camera EOS 5DIII. Any suggestions please? Many thanks, Mike

    I think you've captured the Apollo space craft going to Mars Sorry just my twisted sense of humour. Cant help but from what you say regarding various lens, I would say the problem is within the camera, no doubt one of brains on here will know the answer.

      It is more like chinese broken down rockets fall back to earth. On a serious side have you done a sensor clean manually? there may be a bit of dust that is reacting to blue light?

        It could be a sensor or processing problem ....of course each point of colour is made up of three Pixels with different filters on each....so it could be a damaged filter, blocked filter on the sensor or faulty processing of data from the sensor ...a sensor clean might sort it out perhaps or if it’s a data processing error then a full reset of the camera....Id try a sensor clean first. It’s would be more prevalent on blue just because of the colour mix....the fault might still be there against different colours...might be interesting to photograph some primary colour cards. Just my thoughts.

          Many thanks for your thoughts. I will try your ideas and report back. Processing software is of course AP - what else!! I haven't done a sensor clean so that will be my first try.
