I was about to argue that most EF-M lenses have IS, but I used an R7 last week and that has an 'auto-level horizon' feature that uses IBIS. That improved my pictures a lot, since I was on a very flat island in a big lakeUsed market is usually the place to go, no matter where you are. Almost all these cameras are way overbuilt for how people use them, so chances of getting a good condition body are high. I might pick up an m6ii or m50ii used with a couple lenses for my next abroad trip. Was looking at a small Fuji, Olympus or Panasonic model, but prices on even 8 year old models are still so high, and there's a lot to like about small Canon cameras.
The only reason I never bought into M was lack of IBIS. Of all the technologies to introduce in a consumer-level body, IBIS is by far the most needed and useful. Pros know how to get sharp photos. Amateurs struggle with blurry pics and give up in frustration, using their iphone instead. IBIS should be a standard feature. No one in sub-$1k category cares about new sensors. Just reuse the 80D sensor forever, it's fine! Spend the money on computation and IBIS.
My M6II already has a software auto-level for video, it would be nice if something similar would come to stills as well, it could be an extra metadata field for RAWs.
