EOS RP photo aren't as sharp the ones from my EOS M50

[kingsahibkhan]

Hey i realized that a lot of my RP photos arent as sharp as my M50 at further distances and a lot of times my RP photos are blurry and i never experienced the same with my M50.

The picture at the pier was with RF lenses and as you can see it cannot focus well at all. The other pictures are with a EF 50mm. The clarity of the walking person in with the m50 is just far higher than the people in the RP photo. Please take a look and see if you agree. (zooming in makes the biggest difference.)

Are you still using the mount adapter. Are you still using live view instead of the EVF.

The use of a Viltrox adapter is problematic - there are issues with third-party adapters.  Can you source a genuine Canon EF-RF adapter to try out?  Again, I am trying to reduce the variables here.

I have had a look at the 10 CR3 images on the google drive folder. I have a couple of observations to add to the excellent points raised by my colleagues above.

From the images all that are with the EOS RP use Neutral picture style, the EOS M50 use auto picture style. This might account for two elements, the flat colours of the EOS RP images but also the sharpness difference. When set to Neutral style the sharpening is set to zero. A camera set to auto picture style chooses between standard, portrait and landscape, all three of these have sharpening set to more than 0. I found a sharpening value of 4 in each of the M50 files. Since I had the RAW images, I selected auto picture style for the EOS RP images and this improved the colour and the sharpness of all of them.

Next I noticed that the framing of two shots looked similar. M50 gas station.CR3 and RP gas station.CR3. When I checked the EOS RP was set to 1.6x crop mode, so then we are comparing a 6000 x 4000 pixel M50 image with a 3888 x 2592 pixel RP image. I'm not surprised to see a different level of detail in the two pictures.

I noticed that some shots are captured with high aperture values, mostly on the EOS RP, this can lead to diffraction loss and the EF 50mm f/1.8 STM is not at it's best when heavily stopped down.

My suggestion to more accurately compare the images is much the same as the others above.

Standardise the test images, use a tripod to mount the cameras. Set both to the same exposure, AF and Picture Style settings.

I totally concur, Brian.  That is why I made the comment about shooting against the solid regular object.  These images are all over the place.

Yes very true Trevor the pictures are NOT constant between both cameras.

Good catch on the 1.6x crop mode on the RP Brian. That would mean the pictures would only be 10 megapixels instead of the 26.2 megapixels when its in Full Frame mode. That would also explain a lot about the loss of detail. So the OP isn't getting the most out of their camera. I also own the 50/ 1.8 STM and I don't usually shoot with an F/stop smaller than F/5.6 because diffraction starts to become apparent.

This was the answer, not necessarily the crop part because i tested it with full frame and crop(did not upload the comparison here) and got the same result, but the auto picture style and an increase in quality really sharpened everything that was a distance away, i also changed some additional settings to auto and its been great shooting form my window, will try full on outdoors shoots in a couple of weeks but this already made a world of difference.

Glad you have a resolution and that you don't have to get your camera fixed!
