I always see less noise with the SL1.

What do you think ?

What's an SL1? Is that a Canon?
....I assume the D80 is a Nikon???

Canon Sl1 (100D) Canon D80

Nikon had a D80...Canon has an 80D. Both had a D60.
These names get confusing, that's one reason why brand names are important.

Do you regularly shoot at ISO 6400?
The noise looks similar to me.
Personally, I think it would be more useful to shoot a real image and compare.
Something that has more colors, sharp edges and maybe some sort of scale.

Your horizon is tilted in the first shot.
Correction, both shots.

The white balance seems to be off too ....

I left everything as is just converted to JPG.
Why would that affect noise.

Would that affect the noise ?

Tomorrow I'll do that

No I don't usually shoot iso 6400 I want to shoe the difference in the noise.

D80 is supposed to have less noise but I alays see more than I did with my SL1

The Canon SL1 is an 18MP camera (two generations old sensor and Digic 5 sensor).

The Canon 80D is 33% higher resolution 24MP camera (current generation sensor and Digic 6 processor, just recently some models have been released with Digic 7).

The noise levels of those images look pretty similar to me. That speaks really well of the 80D, since it's got a considerably higher resolution sensor that's both more crowded and has smaller pixel sites. There has been some discussion of the latest 24MP Canon CMOS sensors have slightly wider dynamic range, too.

To evaluate the usefulness of higher ISOs, it really makes the most sense to see what can be done with specialized Noise Reduction software, since you're very likely always do some NR to any images shot at those high ISOs. In other words, you're unlikely to ever use a 6400 ISO image without any NR at all.

There's in-camera NR, though it's largely JPEG-only. With RAW any NR is applied during the conversion or afterward in post-processing. There are a number of choices... Lightroom, Photoshop and elements all have some NR built in. So does Canon's own Digital Photo Pro. In the past I used DPP, when older versions of LR and PS didn't seem to do as well. But now they're all pretty equal, at least with the cameras I'm using (might be different with an SL1 or 80D, neither of which I use). I've experimented a little with Nik DFine, but mostly use and am happy with Imagenomic Noiseware, a Photoshop plug-in (also can be installed and used as a standalone software).

From 2011, I think that pre-dates the SL1... and certainly the 80D. But the info is pretty much the same, though newer cameras have been getting better and better at high ISO.

If you want to see "noise", look at film! Back when I was shooting slides the highest ISO I used was 200, but most was 100 or 50! I used some color neg and B&W films as high as 400, even sometimes pushed the B&W to 800 or 1600... but that was about the limit and there was lots of grain at the higher ISOs. A lot of people today have never used film, so probably don't fully appreciate just how incredibly good and helpful it is that digital can be done at incredibly high ISOs!

Amen to that!
My 3200 ISO color digital images look tons better than the pushed B&W 3200 ASA film I shot. Color that high? Fuggedaboudit! It has opened up photo possibilities I could only imagine before.

First, it's an 80D not a D80. They are both Canon cameras and they are both crop sensors. I think the 80D shows less noise to be honest.
They are both at ISO 6400

I'd bet a $1 that the 80D is actually better... That the difference you think you're seeing is because of how you're viewing the images.

Say you view images from each camera "at 100%". You're actually looking at a more magnified 80D image, than the SL1. This is because of the difference in resolution, between the two cameras.

The SL1 has an 18MP, 5184 x 3456 pixel, APS-C size sensor. On most modern computer monitors, if you view that image "at 100%", that's like making a print 52" or over four feet wide by nearly three feet tall, then viewing it from 18 or 20" away.

The 80D has a 24MP, 6000 x 4000 pixel, APS-C size sensor. Looking at an image from the 80D at the same 100% on the same monitor is like making a 60" or five foot wide by three and one third foot tall print, then viewing it from the same 18 or 20".

In other words, you are probably looking at the 80D image more critically... which very likely explains why you don't think it handles noise as well.

The best way to truly evaluate image noise is with high quality prints on matte paper. That's the most demanding and gives a better comparison than most computer monitors are capable of rendering.
