Oops I did not thought about that. Even with crop-sensor EF-S 15-85mm tend to vignette a bit.

Now, I am thinking either I sell EF-S 15-85mm and go into full-frame or switch to EOS-M cameras for their compactness or EOS xd, xxd or xxxd cameras.

As mentioned earlier, the crop is automatic: the moment you attach an EF-S camera to an EOS R, the body starts shooting at the APS-C crop size of 11.7MP ( 30MP / 1.6^2 ).

It's slightly worse than that. The OP is looking at the RP, which has a resolution of 26mp so with the crop will be left with 10.1mp.

I am dropping the idea of using EF-S lens altogether and use EF and OM Zuiko lenses instead.
But I did not read or know anything about using of manual focus lenses either with R or Rp. If Rp does not support then I will pick R (a bit pricey for what I do nevertheless)

I bought the R for the magic focus aid, extra 4 megapixels, improved dynamic range, dust cover over the sensor while changing lenses, better construction, EVF  and bigger battery.

Both cameras do manual focus peaking or magnification of the focus spot (5x or 10x but not in conjunction with focus peaking).  I use the much maligned M-Fn bar to control the magnification and toggle the electronic level and histogram, so I don't need to lock it or worry about accidentally altering the exposure with it.  The match triangles focus aid is wonderful manually focussing RF and EF lenses and adapted lenses with chipped adapters.  The RP doesn't have that feature, but it does have automated focus bracketing, which is missing from the R.
