Canon R3 sensor issues?

waltzink — Sat, 13 Apr 2024 16:36:02 GMT

So last night during a show my viewfinder started flashing horizontal lines across the screen. Occasionally these lines would end up on the photos. Not all photos I would take were affected but I feel like somehow the sensor has been damaged. It isn't the SD card as it does this when no SD card is in the camera. Not the battery, either. I've also done a factory reset and still the same. Any thoughts on an estimate to have this fixed? The camera is a year and a half old and the shutter count has to be upwards of about 250,000. Thanks!

A show? Any lasers there? And would you mind sharing a raw sample?

No lasers. I've shot at this venue about a dozen times with the R3. Just typical lighting but no lasers.The photo above is from a video I took showing the electronic viewfinder kind of whacking out with the lines. It started happening about 2/3 of the way into the event last night. I immediately thought it was the CFExpress card and swapped it out with no affect. Currently importing the photos to my macbook. Took a photo on my phone of an affected image. Can upload a couple of RAW images later, if needed.

All three below if you bring up shadows you'll see the banding horizontally. This is what is showing in my manual and LCD viewfinder. This just started last night in the middle of the show. Definitely a sensor issue. Just have to find out how severe and if I can repair this via Canon.

Never seen that before. It is not laser damage because it moves around.

There is also a vertical line in the masked pixels with no signal at all. I don't think R3 should have that.

I had an issue about a year ago with these lines showing up on photos but I think it was a bad CFExpress card. Swapped the card out and hadn't had any issues until last night. These lines appear on the digital and manual viewfinder even if there's no card in the camera. I've placed a service request in with Canon and will try to mail it out ASAP. Afraid that it'll be the sensor that needs to be replaced.

Well, if it's a year and a half old it's under warranty.

Date of purchase was 7-13-22. Have it registered on the Canon site. Fingers crossed this won't be an expensive fix but if not covered I'm a bit screwed 😂

Just looked and the warranty is only for one year 😥

Thats correct. It's one year. If you don't have a Carepak, hopefully you can write it off as a business expense or loss if If this is your business and used as primary source of income.

“ Never seen that before. It is not laser damage because it moves around. “

I’ve noticed from 1/320 SS display that Flicker Detection is probably disabled.. I wonder what shutter mode is being used.

At another show tonight. Used the camera just to test other cards which I formatted. Suddenly the tweaking out like you see in the video stopped and the camera now works fine. No idea what is up 😂
