I've been using my EOS M5 more, and I'm wondering if I've been wrong about the FF mirrorless.
The more I use the M5, the more I realise there may not be a need for a compact FF mirrorless if the quality of APS-C sensors keeps improving as it has.
Back when I got serious into photography, I had the 500D, and that was a dreadful camera. The upgrade to the 5D Mark III was astonishing. The difference is night and day. But I compare photos I've taken with the M5 with photos I've taken on my full-frame cameras, and the difference isn't always as obvious. In particular, focus accuracy on the M5 is pretty damn good, one of the biggest reasons I loved the upgrade from the poor 500D to the 5D III.
APS-C mirrorless allows even smaller and lighter lenses than a dedicated FF mirrorless mount plus it's already here, tried and tested. It'd be nice for more EF-M lenses, but I'm sure they'll come eventually.
So, perhaps it is better for a future FF mirrorless camera to be aimed at a different market entirely. Perhaps as an A9-killer. It won't necessarily be what I need, but that doesn't make it the wrong choice.
And maybe instead of a compact FF mirrorless all we really need is a seriously good set of quality prime EF-M APS-C lenses.
Primes may be especially import for aps-c compacts. The zooms are slowish except for the 17-55 f2.8, which pretty much proves the point about size and cost. (and it isn't EF-M anyway) Also, aps-c cameras are not happy at higher ISO's, which increases the importance of fast lenses. For me the key lens already exists, the 22mm F2, so the question is how many more are needed. Another critical focal length for me is 50mm (85mm FF equivalent), and there is now the 50mm F1.8, but it would be nice to have something native. Around 30mm, there is the 28mm macro, which is native, but not all that fast. There isn't anything at 15mm, so that is a hole. So, maybe the glass is half full on the primes (or half empty).
