I recently bought a R5 Mark II and have generally been loving it. My previous camera was a 15yr old Canon Rebel XS, so most of my lenses are EF. I therefore bought a genuine canon adapter to use them with my new camera body. Today I took some macro photos and started to notice the image quality was much poorer in my viewfinder as I was taking the photos. Lines started to appear in my images, which is a big dissappointment. Has anyone else experienced this, and if so how can I rectify? I'm hoping it isn't a problem with the camera itself.
Any advice would be much appreciated. Thanks

Greetings vic_78, and welcome. Your first post here.
Rebel XS > R5 mkII...that's quite an upgrade. I assume these lines are only happening with your macro photography?
Are you using electronic shutter? What type of lighting are you shooting under? Are you using a flash?

Hey Rick, thanks for your reply. I thought it was time for a proper upgrade 😉
I've only noticed the lines whilst taking macro photos. I use a portable LED light that has adjustable brightness and temp. I notice it more with wider apertures, and lower light conditions. Both of which I'm fond of using for the shallow DOF and subtle lighting.
This sounds utterly ridiculous, but I have no idea whether I'm using an elecronic shutter? I'm still getting used to the big jump in hardware.

Some LED lights adjust their brightness by rapidly turning on and off. Is it possible that is what you are seeing?
I have EOS R5 first version, but I hope some of this might be helpful anyway.
I usually use electronic first curtain shutter. https://cam.start.canon/en/C017/manual/html/UG-03_Shooting-1_0310.html
Anti-flicker shooting:

Images may be affected by banding if you shoot under light sources that flicker at high frequencies. High-frequency anti-flicker shooting enables you to take pictures at suitable shutter speeds for high-frequency flickering, which minimizes the effect of this flickering on images.
