Has anyone experienced dust sensor issues that they can't clean off? I have a few on my X-T1 that I can't seem to get rid of. I've tried both of my lenses and used my rocket blower on the sensor glass multiple times. Below is as clean as I've gotten it - f/22 on my 10-24. Most of them start to go away quickly, but there's one spot that doesn't fade out until around f/8. The worst are the two sharp dark spots in the bottom left and the larger dot on the far left. In reality, I probably wouldn't notice these in most shots and they're easy enough to clone out if I did. Should I be worried about this and send it in or just deal with it? Is this just something you deal with using mirrorless cameras? I've always been able to get my 7D sensor spotless.
