Should I stay with EF lenses or move to RF?

[Fordsabroad]

I have just sold my Eos 1dx mk 2 and am switching completely to mirrorless. I currently own an M50 and an EOS R and have an R5 on pre order. I have some good L lenses and am reluctant to swop them for RF ones because, as far as I am aware there is no adapter to use an RF lens on the M series of cameras. I have a sneaking suspicion that a new M series camera with IBIS and who knows what is on its way and if I don't retain my current lenses I would not be able to take advantage of the extra reach of the M series crop.

My current thinking is that I would end up with the R5 as my main camera with an M series as back up (I would sell the EOS R). I shoot mainly wildlife, BIF, a little sport and landscapes, all on an amateur basis. I don't know if an RF to M mount is even possible but if it not I think that Canon are hampering the future sale of RF glass.

I'm in a simular position, I think the way things are going mirrorless will just better and increase in popularity.
I have already sold a lot of my L glass and both of my 1D series cameras. I have an Canon R presently and will start to add RF lenses to my collection.

I have Canon 60D, 80D and EOS R bodies and a wide range of lenses. My EF lenses work flawlessly on the R with the supplied adapter, even the 17-85 EFS - where the R automatoically switches to cropped mode when you mount it. So why wold I buy an RF series lens which wouldn't work with the other bodies? There is no size advantage, the RF series lenses so far are as big and heavy as their EF equivalents. For example the RF 24-105mm F4 is 83.5x107.8mm and weighs 700g (according to Canon's published specs). The EF 24-105 F4L is 83.5x110mm and weighs 780g - i.e. virtually identical in size and weight.

One reason could be when the newer lenses are better than the older ones. Some Canon designs are years old now and the fact is that things move on with newer materials such as coatings and specialist glass and the best modern lenses are sometimes just better than the older ones. Having said that when I had Canon DSLR's I never thought I'd want or need better lenses that the Sigma 50 and 85mm f1.4's I had at that time.

Also legacy lenses may restrict some features which the newer lenses may not.

TBH if it was me I'd be ditching the M series too and just investing into the EOS R if the M series is purely a backup.

Same. Just use the R5 in crop mode when needed or crop in post.

This. If I go for the R6, it will probably be with the new RF 24-105 as it's a bit better than my EF Mk1 version. But I'll not change any of my other EF lenses that will work just like they do now via the adapter, but with the benefits of the R5/6 AF system.

And this too. Canon's M-series is primarily a standalone system, maximising mirrorless size and weight savings, and not really intended as a full-frame back-up.

If you own old L glass { ie 24-105L f4 ) I would sell them and buy RF glass as the reviews are very good concerning build, sharpness & IQ. Newer L glass I would keep ie 70-200L Mkiii & 100-400L Mkii as they will just as good as any RF L glass.
The RF lens that has my interest is the 800mm f11 prime, light, small, has IS, and is cheap, in fact very cheap for a 800mm !

Although I do love the old Canon 200mm 2.8 L that is a dream on my RP... just to stoke the fire. Something nice about using old top end glass on latest models
