EOS R5 ISO Noise

BobK1 — Fri, 27 Nov 2020 11:29:22 GMT

Greetings...I have the R5 and I'm an seeing at 100% crop a significant amount of noise at fairly low ISO settings. In the latest, II shot some images in my kitchen yesterday on the R5 with the RF 15-35 /2.8 at ISO 640 to 1600 1/50sec. Zoomed to 100% I am really surprised at the amountof grain at those settings. Going to give canon a call but wanted to see if anyone else is having any issues. Images are fine at ISO 100 but anything over 400 and I start seeing grain/noise.

Thanks

Bob

Greetings,

This might be related to the type of lighting in the kitchen. Was it natural lighting?

Can you post a pic for us.

Is it worse than what you see on this page?

Yes much worse than that at the same ISO's. Called Canon today and I am sending it in to have them look at it. I'll update once I hear back

Just out of curiosity, in the 100% crop you posted above, where are you seeing excessive noise? Maybe it's my monitor or my eyes or your jpeg processing or maybe things got smoothed our a bit when you uploaded this image here. But when viewed at 100% on my end this shot looks incredibly clean to me for being shot at 1600 ISO. Plus being shot with mixed ambient lighting with what appears to be a fairly wide dynamic range. Am I missing something here?

It's normal for digital cameras to show increased noise as ISO increases. I think your expectations are too high.

Do you shoot as JPG or RAW? The in-camera JPG processing should be pretty good when it comes noise reduction, and the RAW processing by Canon's DPP4 software should be even better.

hi,

I don't think my expectations are too high. I do shoot raw and use lightroom and Photoshop. Looked at similar images from Dustain Abbotts reviews on this camera, mine at the same ISO are so bad. You should see minimal noise and grain on this camera below 640-800 ISO. But thanks for the comment

Contact Caoon Support, and let them test and inspect your camera.

Just to be clear, I'm not being critical of your observations. I've never even shot an R series Canon or spent much time studying its performance claims and improvements.

It's just that I've studied your sample pic at 100% and pored over shadow, highlight and mid-tone areas and find it acceptably clean to my eyes. But then I'm still occasionally amazed by how well my 60D handles noise at 3200 if the lighting is decent and I hit the exposure pretty close.

Lightroom and Photoshop are antiques. But that's honestly being to kind to Lightroom.

No worries...I get it. Some of my 6D images look cleaner, but i may just be diving too deep on pixel peeping. But actually the images look better in my 13 Mac book Pro than you 27" desktop computer 2050X1440 monitor. The JPEG posted really doesn't look bad here.
Oh well.....

Ok ....how do you edit images?

Re: EOS R5 ISO Noise

I always export from Canon DPP, then I use Photoshop to do tweaks. I had to quit using Lightroom, it's worthless.

They used to hire people who knew what they were doing at Adobe. Now I think they are staffed with HS drop outs.

With all the computational stuff goin on in photography and not a wit of it to be found in any Adobe products... sad.

I'll take a look, thanks

Hello,

I too am having excessive noise at low ISO. The first few outings with my new R5 things were great. Now I can't take a picture without what I consider massive noise.

Also, it is freezing up. Every time I take it out it freezes at least once if not 2 or 3 times.

What's going on?

This image is at 1/500, F11, ISO 1250 Zero editing. straight out of camera.

Please help. I don't want to turn this back in but sounds like my camera is having lots of issues.

Wow that is way more niose than I ever had. I would diffently send it back or return it where you bought it. I got noticethat they are fixing mine, no idea yet thwt they are doing to it. Went it's returned to me I will up date here.

Feeling very sad about this.I didn't even mention the issues with what some are calling banding though I am in natural light. I am in burst mode, lens wide open and half of the images are fine and the other half are yellow casted and excessive noise.

Thanks for your thoughts.

The image dimensions are 688 x 496

At least some image processing was done to the image to make it that small. Is this a tight crop?

I would not describe ISO 1250 as "low ISO". It is more than three stops, almost 4 stops away from ISO 100.

PatriciaThomas — Sun, 06 Dec 2020 01:51:30 GMT

Yes, sorry. This image is a crop. 1250 I could use without any problems with my other canon bodies. The first week with my new camera I didn't have problems but now problems seem to be multiplying daily. Freezing/locking up, yellow casting and excessive noise during burst modes and lens wide open (half are good, the other half will be casted but it is not banding and in natural light).
