EOS R6 Mark II - Noisy / Lack of Sharpness help (not ISO related)

[tmoney275]

I have been shooting with a R6ii w/ rf 35mm 1.8 lense. All was good first day out and got some great shots. Shooting at F2.0 / auto iso / 1/1000th shutter. Photos were pretty sharp and no real issues.

I went out today and shot some photos. Very bright conditions out so i stopped down to f5.6 / 250 iso / 1/1000th shutter. I had some crazy issues with my photos looking very grainy and noisy. No idea what the issue is. Seems that if i shoot at wider aperture around 2.0 I am getting way sharper results, even with higher ISO. 

Any thoughts would be greatly appreciated!

Here's a link to some photos. The first 4 are decently sharp photos we are happy with. The last 4 are the grainy ones with the last photo showing an upclose look with camera settings.

These pictures don't have any metadata attached and they're NOT in the RAW format. Are you sure its a sharpness issue or a depth of field problem. Did you previously shoot with shoot with an APS-C camera. Most lenses aren't their sharpest at wide open. Also a wide aperture such as F/2 has a lot bokeh (background blur) making it easy to have things out of focus. Even when not intended.

I hope some of this might be helpful.

Do you have the camera set to save a raw file as well as JPG?

You could get greater depth of field with F/8 or F/11 instead of F/5.6.

Is the unsharp mask applied in the camera or in other software?

If planning to use the out of camera JPG file instead of editing a raw file, then you might want to turn on the "digital lens optimizer" https://cam.start.canon/en/C012/manual/html/UG-04_Shooting-1_0280.html#Shooting-1_0280_4 and turn on "chromatic aberration correction" https://cam.start.canon/en/C012/manual/html/UG-04_Shooting-1_0280.html#Shooting-1_0280_5 and use "picture style" "Standard". 

I suggest that a shutter speed of 1/1000 is much faster than needed. It might be good to try 1/250.

If you want foreground and background to be clear as well as the climber, you might use Av mode with F/11 or even F/13 and leave ISO and shutter speed to auto. "digital lens optimizer" will remove much of the small aperture diffraction blur from F/13.

Yes, fully aware these are not raw, its a google photos album to share some examples...... 
I appreciate your response although i don't think you read my original post? I am aware of how lenses operate at their sharpest, which why I am confused and posting here for ideas.....We are saying the same thing. I'm stating that my first shoot I was shooting a f2.0 and got sharper results than i did today with f5.6 and up. Far more noise in my narrow f stop photos. I will upload some raw files.

Apologies. I only shoot in Raw. Just uploaded some raw files with meta data. The first two I am mostly happy with from last week. The last two are from today and have some grain / noise issues. Dont know if it was just a light thing or what.

How much are you zooming in on your pictures. If you zoom in to 100% you will see exactly what you say. Also is lens correction on too. RF lenses usually shoot a little wider than the stated focal length. This is to account for lens correction. EF lenses did not account for this because lens correction did not exist when the EOS system was released in 1987. Also I originally responded on my phone which has a much smaller screen than my laptop. Do you have Auto ISO ranges set up in the camera.

These pictures still lack metadata are you sure it wasn't stripped out when you uploaded them.
