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!

Yeah, zooming in to 100% and can see a noticeable difference in sharpness with todays photos vs the ones I took last week. All lens corrections are turned off in the camera. All settings are the same other than ISO, Aperture, and Shutter. Generally I manually set my Aperture, Shutter, and the run Auto ISO and just make sure I'm not getting too high with ISO.

If you click on each picture and hit the info button on the top right you will see the details for each photo

I found the EXIF Data. You do realize that pixel peeping will result in loss in quality and detail. Do you normally pixel peep. Cropping a picture also has the same affect as pixel peeping does. I would turn on lens correction too. Some lenses will show very noticeable vignetting if lens correction isn't turned on. I'm not sure if that particular suffers from this.

I appreciate you taking the time respond but we are way off track here on the varying results I am getting with my set up. Pixel peeping is the not the cause. Thanks for the thoughts. I'll wait for some others to take a look and respond.

The pictures look fine on my end but again I'm not working on my desktop computer which has 2 24 inch 4K computer monitors. I'm currently using my laptop which has a 15 inch screen. Now pixel peeping at 100% I do see noise but its not extreme like my old EOS 40D at ISO 1600. Which is H1 on that camera the ISO range was much more limited on older cameras. Also the extended ISO range for that camera was ISO 1600 & ISO 3200. Do you have your Auto ISO range set in camera. Or is it set to allow the entire ISO range instead of it being limited.

On the second two photos, I am not seeing noise so much as a bit of overexposure and some reduction in contrast.  The issue could have been the light angle and dispersion with moisture in the atmosphere.  I have run into that issue multiple times on hiking trips to the Smoky Mountains where subtle changes in natural light make a tremendous difference in photographs regardless of lens, exposure triangle, etc.  I have run into the same issue shooting afternoon sports where lighting doesn't create excessive glare or "hot spots" of over exposure but simply results in a somewhat washed out photo that can be somewhat corrected with contrast along with shadow and highlight gain settings during RAW processing.

***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.

The CR3 files there are not downloaded as raw files.

As you can see Picasa from Google exports the raw files to JPEG files.

This likely an issue with uploading to google. Regardless, I am importing from the SD straight to Lightroom. I only uploaded to show the difference in picture quality which can be seen whether its a JPEG or RAW on google. I appreciate the thought but not related to the issue at hand.

This is super helpful. The light was a bit odd, the sun was directly over head and made for tough conditions. Wondering if its a combo of lighting plus narrow F stop. Thank you!

It is like this every time CR3 files are shared via Google Photo. Not just this time with your files.
