Don't know if this should be in the camera section or the lens section .....

This sample is of a night shot that i took at night @f16 on the above lens. Does anyone here know what these circular bands are ???. Its present on Raw files when i try and crank the exposure up a little in post.  It happens with or without a polarising filter as i thought it might have been from some sort of glare from the diaphragm on the sensor.

Any ideas ???

maybe lens glare? does same happen in video? what about different lens?

Some form of glare was my inital thoughts too, but don't have a second lens to test with it just now.

What's really strange is the out of Camera JPG's are not affected and only the raw files as i shoot both raw/jpg at the same time.

Have tried it in a few different software packages like camera raw/ lightroom and on1. They all have the profiles for this lens so its not down to software i don't think 😕

Shading compensation just fixes the vignetting I think?

It's a circular pattern applied to the RAW data before writing the RAW file in an attempt to fix vignetting. But it's not perfect, so it can cause what appears to be a circular banding - Especially when the exposure is heavily pushed in post.
