EOS R5 Excessive Noise

hervegodbout — Wed, 28 Feb 2024 13:35:26 GMT

I do lots of wildlife photography with my R5 and compare it with my fellow photographers who have the same body camera for some reason, I have lots of noise in my images and they don't.
I always shoot with electronic high-speed continuous plus.
Can someone tell me if I have to adjust any settings in the menu?

Upload a couple of raw files you feel are noisy.

Peter. I sent you edited files. I'll forward later unedited raw files.

What lens and focal length are you using? How far aware were you?

What were your exposure settings? Camera AF mode and AF point settings?

Has this image been cropped?

Seems like sharpening has been done to the pictures and some kind of noise reduction also.

I'm using a EF70-200mm f/2.8L IS II USM.

The settings are: F 2.8 / 200.0mm / 1/3200 speed / ISO 640

I mostly use animal tracking AF point

It has been cropped and edited with PS.

I do have a smart sharpening software and downsize the images to 2048px for social media.

Thanks, for the quick response. Can you show us a JPG of the original uncropped image?

One issue you have is over exposure. Underexposure and even over exposure can expose all sorts of things in an image. Do post an unedited sample. (Don't apply the, "smart sharpening software".)

Just posted unedited sample above without "smart sharpening software"

I am not seeing any extreme amount of noise in that sample. You may be a victim of over cropping in an attempt to try an increase the size of the hummingbird. With a 200mm lens you need to be awfully close to the small bird to get a decent size subject in the frame.

When I shoot hummers I am about 20 to 30 feet away. This is my setup a 1DX with a Sigma 150-600mm Sport super zoom lens.

I caught this somewhat annoyed hummingbird chasing off a bee from the feeder.

With the big 600mm lens it doesn't require as much cropping to get a reasonable sized subject in the frame but it still does require a fair amount. Solution crop less with a bigger lens and see less noise.

Got it! I know looking at a he new RF100-400 2.8. Looks amazing!
Than you for the tip. 😊

Hello Peter, I shoot wildlife on an R5 with a RF 100-500 lens. Usually I get sharp, low noise images I am very happy with. But this most recent time I did some shooting I feel that the images are not as crisp. I'm wondering if something happened to the camera. If I upload a couple of good (taken previously) and bad (most recent) raw files, could you please help me understand what may be happening. Thank you.

Heat distortion is my guess, so not a problem with your equipment.

You have some hot pixels visible in daylight, so perform a sensor cleaning via the camera menu to remove them. Perhaps more visible due to camera temperature.

I hope some of this might help.

The differences I noticed between bad image 1 and good image 1 include camera temperature as Peter mentioned. It seems to me that with my EOS R5, noise increases rapidly as camera temperature increases. I have read that for CMOS sensors, thermal noise doubles for each 6 degree C increase in temperature, so one might expect bad image to have roughly 4 times the noise as good image. For a camera with IBIS, cooling the sensor chip is more difficult.

Camera settings that seem to me to increase noise include enabling auto lighting optimizer or enabling peripheral illumination correction. Those are easily done later in Canon DPP software.

Camera temperature seems to stay lower for me if I close the live view screen and in power settings have the viewfinder turn off quickly.
