EOS R50 RAW images noisy and not sharp

[g_khajanchi]

Hi, I am shooting photos in only RAW format with Canon EOS R50, but there is noise in the photo and not sharpness. 

Any other function settings are needed only for the RAW format, so that the photos do not contain noise and maintain sharpness.

Many of the raw files are under exposed.

Yes, in this folder RAW, CRAW, JEPG, etc file different exposure.Yes, in this folder RAW, CRAW, JPEG, RAW+JPEG, CRAW+JPEG etc file with different exposure.

I hope some of this might help.

For _MG_0965.CR3, camera temperature is "CameraTemperature : 42 C" and higher sensor temperature will mean more noise. If the temperature in the room is cooler or if the camera had not been in use for very long the sensor would be cooler and there would be less noise. The _MG_0965.JPG file does not appear to me that it came out of the camera, but maybe was produced by converting an HIF file to JPG? The image would not have been so dark if the camera were set to sRGB and then one can use Canon DPP software to save a version as HDR PQ or as AdobeRGB color space when editing the CR3 file. What software do you use to edit the CR3 file?

ISO is 6400. With a small sensor, there is likely to be noise.

in Canon DPP software, noise reduction defaults to 11.0 chrominance and 11.0 luminance which is a lot of noise reduction and will likely make the JPG look better than the CR3 without noise reduction. The noise reduction will soften the image.

Peripheral illumination correction was enabled, and I suggest disabling it in camera and using Canon DPP or other software to do it when editing the CR3 file.

Digital lens optimizer defaults to 15.2 in DPP which suggests that it was enabled in the camera. More digital lens optimizer is possible with a lower ISO number. Setting "HighlightTonePriority : On" in the camera might result in more noise.

In the camera, you had set "HighISONoiseReduction : Standard" and "DigitalLensOptimizer : Standard" which will make the JPG look better than the CR3 file for some software used to view the CR3 file.

Auto lighting optimizer was off which is good.

In the link you can see the photo of God and a boy which is a raw file.

I would say that 0965.CR3 is under exposed by at least 2 EV.

The file 0501.CR3 about 3 EV. The shutter speed was 1/4000 second. 1/1000 second or even 1/500 second would still work.

0001, 0002 and 0003 seem normal. A lot of light and low ISO.

Use a tripod for non moving targets. For people you may need a faster lens.

Looks like you selected Manual exposure setting. Did you adjust one of the variables (Tv, Av or ISO) to center the exposure meter? As Peter said, the ones I sampled were all underexposed. If you boost the exposure on an underexposed image you will get noise.

Use Program mode and see what your results are.

I totally agree.  This is a result of under-exposure and not an inherent flaw in the hardware of firmware.
The RAW file gave the OP what they shot.

Camera temperature belongs to white Balance/Kelvin or other means

The camera has a temperature sensor and reports the temperature in the metadata. If the environment is cooler, or if the electronics in the camera are using less power, the camera will be cooler and there will be less noise.

Color temperature in Kelvin may be set when editing the the CR3 file by changing the white balance.
