Canon 5D Mark 4. Part of a photo has different color.

avcheprakov — Tue, 30 May 2023 16:50:25 GMT

Canon 5D Mark 4. EF24-70mm f/2.8L USM

Three photos below have:

ISO 800, f/11

Shutter speeds 1/200s, 1/320s, 1/500s

After 5 years of owning my Canon 5D Mark 4, which has never behaved strangely, yesterday suddenly a strange thing happened - some photos began to look incorrect - as if part of a photograph with a changed color. What could it be?

Fault with the sensor perhaps? Most rows only returning green data (no red or blue)?

Maybe try a different SD and/or CF card to see if that makes any difference.

Also try resetting the camera in case there's some feature that is causing this (dual pixel RAW? corrections such as peripheral illumination?)

Hi Ricky.

Thanks for the quick answer. I'll try to reset. But these issues happen not too often, so it is hard to replicate it. I'd say - chance to replicate it is 1 by 30.

Some has magenta hue:

Some has neutral, but different in brightness:

Sounds like a bad memory card or a bad image sensor.

Changing your memory card to a new one is easy to do. Be sure to format the card prior to first use.

Hi Waddizzle. That's interesting. I'll try it for sure. Thanks!

How are you downloading your images? If using a card reader, try a different card reader and a new cable. A bad card reader or cable can corrupt images.

Hi 5DIV!

You're right. As soon as I re-inserted the card into the reader, the problem disappeared. Brilliant! Thank you very much!

Cordially,

Alexey Cheprakov
