EF-S lens in EOS R

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.

1) I need to upgrade my ageing EOS 450D

2) At max I upload in flickr or print them on 13x18 cm if they are family portraits.

One hand side I like looking through the view finder and still owns many OM-1n cameras (please to look through the VF) and some medium formats. And on other hand modern tech and compactness are desired at many occasions.

Hello all,
I am eyeing EOS RP and I believe mirror-less could be the future. Otherwise my immediate choice would be 6D mark II
Yes there is a nice adapter that takes EF and EF-S lenses and currently I own EF-S 15-85mm lens which I like for casual photos and an EF 50mm lens for portraits (not pro)
My question is how is EF-S 15-85mm on EOS RP. I am aware there is no crop-factor and dof is as it as.
So I am looking mainly the performance and other factors if any?

If you go for FF, you will not find the 15-85mm much use. It won't fit onto any FF canon DSLR, and it will automatically crop to just under 10 megapixels on the EOS RP or just over 11 on the R.

For the price of the RP I would recommend the EOS M6ii, a much more advanced 32 megapixel camera than the RP, which will take all your lenses (including the OM ones) and it's smaller than your EOS 450D. Your EF and EF-S lenses will give their best results on the M6ii. It does have a detachable electronic viewfinder; if you want one built in, consider the simpler and much cheaper 24 megapixel EOS M50. If money is tight and you're not bothered about an EVF, there's the M200 or the end-of-line M100, also 24 megapixels.

Going full-frame mirrorless isn't going to be worth it unless you also buy the 24-240mm RF zoom or one of the several 24-105mm RF or EF zooms.

your 15-85 will work much better on the R than on a 450D you will have better dynamic range and better ISO evan in crop mode on the R and waaaay better AF..also if you get into video the 15-85 will be a good lens at the R shoots 4K video in crop anyway

looking at what you do you won't be MP deficient anyway ..but thier will be a lot of unrealised potential

your manual focus lenses from your OM cameras will work splendidly adapted on an R.. focus is easy with focus peaking or the 10X loupe that you can have anyplace on the tuch LCD in a couple of dabs and a swipe adaptors are cheap on ebay ...be warned MF glass it can become ....addictive

I have Zuikos from 24mm - 135mm except 100mm and macros. I rather sell 15-85mm, if Zuikos goes well with R/RP.
If I get it right then I may also need OM-EF adapter + EF-EOS R?

You can get adapters straight from OM to RF (or OM to EF-M too).  The minor advantage of going the OM to EF to RF route is that the OM adapters are very slim, so buying a lens for each adapter would not increase the size of the adapted lenses very much.   The big advantage of going the OM to EF to RF route is that the match-triangles focus aid of the EOS R needs to know that there's a lens mounted. Canon does that by the body checking for an electrical response from the lens, and a chipped OM to EF adapter will give that. Some older chips, however, will confuse the camera. The RP doesn't have that focussing aid anyway. Otherwise you can use focus peaking or focus magnification, but not both at the same time. I don't think anybody makes chipped lens mount converters to RF mount yet, even though they would only need to tell the camera an adapted EF lens was mounted and that can't be too difficult.

Now I am strongly biased to R/Rp and perhaps some Zuiko f/2 lenses. I turned 40 this year and still shoot film and have a nice darkroom in the basement.
I let go 15-85mm and start saving for R/Rp

Sounds sensible. Hang onto your 450D if you go for individual chipped EF mount adapters as that body will definitely let you program each chip to tell the camera the focal length and maximum aperture of its lens. That's useful for the EXIF data (it won't tell you the actual aperture used, but it will identify the lens) and could be useful if you subsequently buy a body with IBIS.

You would also be able to use your OM lenses to give manual focus confirmation with your 450D.  That 135mm Zuiko would give you a very compact 200mm FF equivalent lens.

If I can say honestly then one thing that I really don't like to have is the video feature in a DSLR (may be I am not so mainstream)

A kind of modern 450D, that have a full-frame, good auto-focus and AF-points, minus optical view finder, a better connectivity and grip. But...

Two pics. EF-S 18-55 at 50 ( 4.5MB) and rf 24-240 at 50 (9.5MB). The ef-s lenses can only be used in the 1.6 crop mode. EF and RF lenses in both and 1:1 , 4:3 , 16:9 mode.

I think camera did a great job despite throwing a kit lens (EF-S 18-55).  Nice comparison and thanks for the effort.

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.

The video is really a by-product of the hardware you need for the EVF and the computing power you need for the good AF and AF points.  The slight extra cost of the firmware for video is more than cancelled out by the economies of scale from selling to all those who do want video.  If you're serious about not wanting video, look what it does to the price of the price of a Leica.

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.
