Anyone come across any banding issues yet?

[Tony Parenti]

Was wondering if anyone has experienced banding yet in shadow areas. In some of the jpegs Ive see I swear I see it but might be my mind playing tricks on me. Does it stripe in highlight areas supposedly like the Z7 does? How is it that Sony sensors in their mirrorless have no banding? What are they doing different?

Came here to check if others experienced it.

I just tested my new Eos r and pushed an underexposed shot 3,4 and 5 stops and in the darker parts I see massive banding. It shows up even at 2,5 stop push now.

I didn't notice it before in outdoor shots but this is a dimly lit room at 5 o clock in the afternoon and I can't push shadows more than 2,5 stops.

I think I'm going to return the camera, my 5d4 doesn't show any banding.

I'm truly bummed out!!! I loved the camera despite of the missing dials and buttons from my 5d4


2,5 stop push 100 crop / iso 100, 1.4 , 1/160


5 stop push 100 crop / iso 100, 1.4 , 1/160





edit: I am used to not being able to push 5 stops. but not being able to push 2,5 is useless for underexposing landscapes, cityscapes and even backlit subjects. as with a moderate push and some shadow boost there's banding already

Hmmm... any other opinions about that?

Did you comvert to dng?

What if you export to tiff? .. does that happen in DPP as well?

 

[Tony Parenti]

Wow. Thats pretty embarrassing if true. How do you even release a camera that performs like this in 2018?

 

[mmeerdam]

Tested it again, just now in a bit more real world scenario. It's not that noticeable but it's there and when shooting a landscape or concrete building with dark color it will be all over.

This is iso 100 and just a 3.5 stop push. 5d4 is noisy but no banding.



dng convertor - opened in photoshop. will test in c1 and dpp now.

I feel like I just bought my 5d3 again

Capture one DNG: shows banding from 2,5 stops
PS (ACR) DNG: shows banding from 2.5 stops
CR3 in DPP: shows banding from 2,5 stops




C1 - screenshot @ 100% 2.5 stop push




DPP 2.5 stop push

Gross. The 5d2 and 3 dont have banding across the whole frame. Theres shadow noise no doubt. But not lines across the whole frame.

RAW or C-RAW ? Electronic Shutter or not ?

 

[Tony Parenti]

Please help me understand. How do you switch between manual and electronic shutter?

 

[mmeerdam]

RAW uncompressed 100 ISO,

It's worse I can see it at 1 stop push TBH.

directly in photoshop, no tiff no jpg conversion, just opening it in act shows banding from 1 stop push in the file with the bottles

 

[Tony Parenti]

As a DNG though right? People are saying DNG conversion is the issue. Can you open in DPP as the RAW file, not DNG, and export as Tiff and then try? When you opened in DPP was it as a RAW or DNG? Also was this under florescent lighting?

 

[DeeNikon]

Tiff is no raw format anymore...maybe this information is just lost because the tiff does not have the DR anymore?

I see banding in DPP with iso 100 very high contrast and pushing brightness at max and shadows too.

but normal push in DPP is fine.

same as 5DIV btw....

 

[DeeNikon]

Could you post r and 5d samples of your experiments?

I posted a cr3 imported in DPP half way the first page of this thread.

A 2.5 stop push shows a little less visible banding but it is also darker, so i would have to push it more and banding will be even more visible. It's still there. I was hoping it was the DNG conversion but the banding is in the original CR3 uncompressed raw file in DPP. If DPP shows it it's there. Even before conversion to anything else i see it on my screen. 5d4 is clean.

Puh.. i will try to return mine on monday. Glad it is still in the box.

I did not want to get involved in this but I hate to see you return a good camera. When I read the OP's post this mourning, I did some testing on my own.

ISO 100 pic with some black shadows, converted to a tiff and loaded into LR. There was very bad banding, my heart sank. Than I remembered that good old Tony found that the converter can do this. I went back to DPP and looked for banding in the CR3 file at + 5 on the shadows with +3 on brightness (both max) there was VERY little banding and you really had to look for it.

I will not post pics, take it as you will. Think of this CR3 is a new format and maybe just maybe no one has a good converter for it yet. Could be why LR still cant load CR3 files.

I received my EOS R yesterday and started to play with it last night. I wanted to see how the AF was in low light (it is excellent FWIW), taking photos of my dog. I did see significant banding in the underexposed shots I took with my 50mm f/1.4 but did not see any in the shots I took with my 35mm f/2. The 50mm lens also exhibited some strange distortion in the EVF in low light. So far all of my issues are specific to that lens.

What also concerns me now (had not thought about until someone else raised it) - IS is always on on lenses... suppose thats not good in the long term.

It's not. IS is on only when you're seeing a live image on the EVF or the rear display. If you have the rear display folded close and you're not near the EVF, the evf will turn black in a few seconds, and the IS will stop. If you use the rear display it will stops after 30s if you set the screen to blank in 30s down from 1 minute default (which I will do anyways).

Concerning the banding, yes, I see it, if I severely underexpose the shadows. It seems to be down on the very black level, so it's not how much you lift, but rather how much it was underexposed. Some ISO seem to be worse than others (I get it worse at 800 than 3200, and having a really hard time to get it at 100, not sure if it's the random noise masking it)

On the good side, it's random, doesn't seem always to be entire lines either, it changes pattern in every photo. I'd make the wild guess it's not the sensor, but some calibration issue/electrical noise. They might patch it.
