EOS R5 - How Do I Remove This Grid Pattern?

[peterdenio]

Canon R5, RF 100-500 lens, F7.1, ISO 200, Shutter 1,000/sec

I've looked at "View", "Grid" to no avail. Any thoughts? getting this on some but not all from this beach series.

Is this a crop or the entire image?  In either case, looks like an issue with the sensor.   First reset the camera back to default settings.  But most likely you'll need to send this in to Canon for repair.

Do they look like this on the camera screen or only after downloading to your computer? If ok on the camera, you might have an issue with your card reader or cable.

If I did not know any better, I would say this photo looks like it was shot through a window screen.

That was my first thought as well.  However, the colors are very strange.  Almost some kind of posterization effect.

I was thinking the same thing too. It looks like it was shot through a window screen. But the colors are very strange too. I don't use lens filters (except for a clear one/ protective filter) or know how they work. But could there be a polarizing filter attached to the lens. Causing this strange pattern to happen.

A polarizing filter wouldn't do that.  It will only remove/reduce glare. Plants/foliage become more green with a flatter appearance, skies can also become darker blue, and surfaces of water or even windows will have less reflections.

Thanks for the info Ricky, I don't use filters so I don't have much knowledge on them. Then photo is my hobby. So I'm no professional when it comes to photo.

Not shot through a screen and no filter.  Only a few photos in the group of 500 had this pattern.  Could not determine a setting that was similar to affected pics.  Seemed random.  Not sure if its camera or Photoshop/Lightroom caused

Does the same effect happen when looking through the EVF or looking at the rear LCD screen. It could be a bad card, bad card reader or a bad USB cable.
