Started to notice issues on my photos, wondering if anyone knows what it could be or is it something more serious with the camera body?
Canon 5D IV with 70-200 2.8 IS III
Was processing a few photos i took yesterday, dehazed a few and notcied white vertical lines to one side of the image.
Took a sample photo of the current cloudy day, ISO is 6400 (which is when ive started to noticed it), there is a lot of noise, i know, done this to make it easier to highlight the issue.

Share some raw files instead.

You can share a link to a reputable filesharing service like OneDrive, Google Drive, DropBox, etc.

Is it present BEFORE you applied the noise reduction to the images?

It was a few white stripes running down one side of the photos that I noticed first, did the dehaze to the max to highlight the effected area

Your posted image seems like it is a tight crop. It lacks context. This is why others are asking to see a sample. So am I.

do you notice the dark lines down the right side, from top until half way?

Yes. Share a couple of raw files.
I would like a raw sample with a shutter speed longer than 1/180 sec, preferably towards the sky. This to rule out the shutter.
I would like two pictures of a white wall inside. Exposure longer than 1 second for both, but one with Long Exposure Noise Reduction turned on and one without. This to see if a dark frame will remove it.

Please post a RAW file or two, especially this one, I see black lines on both sides running from top to bottom on multiple devices. The resolution is also quite low. Is this image a screenshot?
If you are using any lens fllters, then please remove them when you capture the images Peter suggested.
What software or workflow are you using to move or copy the RAW files from your camera to a computer? I assume that you are using a computer. Correct?
