    Since a couple years back I started noticing a black vertical line near the middle in every photo. After a lot of trial and error I realized this only happens at ISO 100. Here you can see it slicing through the hibiscus. I attach also a photo at ISO 200 for comparison.

    So... I can live with it, but it's a bummer. do you have any tips? Searching around the internet tells me basically the sensor might need replacement, and then one might as well just get a new camera.

    Is it really a broken sensor if it only happens at ISO 100?
    Firmware update did not fix it.

    Thanks in advance for tips!

    Does this line show on:
    Live view - a loupe might be needed to see it
    a RAW image?
    a JPEG image?
    Both?
