Red Lines Sony A7R5

[magnoliasc24]

I'm hoping someone can help me.  These photos are from Sony A7R5 and you can see a single red line going through each image.  This happened on about 50 photos out of 800.  B&H let me return the camera and now I have a new copy that did the same thing.  I've seen zero reports of this issue for this camera.  At first I thought it was some sort of sensor issue, but this would seem extremely odd to have two cameras with this issue.  I'm now thinking that it's possibly a corrupt memory card, but I have been unable to reproduce the situation.  Anyone have experience with this?  Any thoughts or recommendations?  Thank you.

Did you crop any of the 2 shots? If not I'd say that the lines are not in the same location so I think the problem is with the memory card. Try another reader or try import via USB cable directly from the camera and see if that makes any diff.

Not sure he'll see these responses, he hasn't been back for several weeks. Still, I'd like to know the outcome. Was it a card?

Hey MickDK,

Thank you for the response.  Since I posted this, I have continued my troubleshooting and also came to the conclusion it’s a memory card issue.  However, I have been unable to recreate the situation with this card but also have not experienced it with other cards I’m using.  I don’t think it’s the card reader because the issue has happened twice on two different computers using different card readers.  Maybe I just need to take more pics with the suspected card and see what happens.

I feel pretty confident now it’s at least not an issue with the camera sensor as it’s also two different cameras.  
 

thanks again!
