Will Canon allow EF lenses to work on future RF bodies?

I'm sure Canon won't disable EF lenses on future bodies.  They will work with future bodies at least as well as they do on the original EOS R, possibly better as a result of improved focussing systems and global shutters. I know that I enjoy the experience of using my EF lenses on my R more than I enjoy using them on my 5Ds, largely because of the improved mirrorless focussing and handling.

I bought my EF 16-35mm f/4 lens after I bought the R because the RF 15-35mm was several times the price and only just introduced. One of my RF lenses was a stop slower than the EF equivalent, but it made up for that by being more than a kilogram lighter and a fraction of the price. The 16mm had no EF equivalent.

It's the market preference for new RF lenses that will kill off EF, no need for any shenanigans with future bodies. Right now with current pricing and with R&D, assembly lines, certification and training long paid for, EF lenses are probably at least as profitable for Canon as RF, so the main pressure to stop making them is lack of sales.

I think the answer is YES, EF lenses will continue to work if not explicitly supported,

however there is no guarantee that there won't be future camera features which will only work with RF lenses because of certain EF lens electromechanical performance limitations. And perhaps Canon will contrive to make that happen

That much was true from the very beginning. There are already features that only work with RF lenses. That's not a matter of "contrivance," that's a matter of progress.

yes but Canon might design some features that only work with RF lenses - could be some form of advanced in-camera focus stacking etc - ie features deliberately designed to add value to RF lens ownership but offer nothing to EF lens users.

They might do, but more likely to innovate rather than out of malice. If you have a great new idea and innovative feature do you not produce it as you know it will not work with legacy products? Of course not.

I'm not suggesting anything would be done out of "malice" but rather developments deliberately designed to make RF lenses more attractive and to give EF lens owners some incentive to switch 'up' to RF

Peter

I am sure you are not, but plenty imply that which I always find odd. Often it is such a lot of work to retain backwards compatibility that it is not worth it or even possible.
