I realized a comparison between two old Canon of 2002-2003

Again, visually the Canon T7i (800D) camera and the Canon M50 MKII seems about the same as far as ISO and image quality goes. I really haven't seen all that much of a difference. That's why I mention them both interchangeably.

There's days I'll just use the two mirrorless cameras with the small lenses if I don't want to carry around all that weight. I'm not sure if the M line will end or not. But I figure I'll use those M50 MKII cameras for probably three more years unless something comes up a lot better. Then I'll upgrade again. Or I may get a wild idea to get something else for no reason at all, other than I want it.

reading these forums tends to do that. basically i run on two tracks: everyday shooting is done with a couple Bridge cameras, but special events demand the DSLR.

It's a total guess on my part, but I think Canon wants to keep the R line for both full frame and crop sensor cameras using the RF lenses. The Canon M line would fade away...but maybe not...I think it all depends on profits...so it would be a Canon business decision. Also note that the Canon EF-M lenses are limited to a small number.

and it could be that canon advances so much that it leaves all of their present lines in the dust. there is some photographic tech on the horizon that might possibly do all of that. it seems that lens tech just creeps along slowly but everything else is racing to the moon and beyond.
