RF, EOS R and new Tele Lenses

[PatrickH]

Maybe I missed this in the press release, but what is the effect of putting an EF-S lens on the new mount? Does anyone know if the sensor has a crop mode?

I'm loving my M for backpacking. I consider the EVF and battery life to be compromises, but the weight savings and size reduction are phenomenal. CPL/ND filters are very affordable, and the world of tiny tripods opens up. I initially thought about switching to a FF mirrorless system until I realized I was adding almost all of the weight and size back with FF compatible lenses. I now use my 6D for shorter hikes, family/portraits, or for when I have a car (national parks etc.), and am using my M for when I am on the go/on foot for long distances.

No doubt that the market is moving this way, and the 28-70 f2 sounds incredible, but I don't see giving up my two camera system any time soon. That said, wondering how compact of a system one could create with this new mount. None of the new lenses look particularly small. While not M small, I could see a viable travel/backpacking EF-S setup.

Yes, it has a crop mode. So you could do a EFs lens on it. You drop down to something like 11-12 MP, but that is still a nice base image size.

I have yet to see a thing that makes me think mirrorless is more than a very slight gain in size weight. A few 100 grams. Which is not much for most uses. About the weight of my L bracket.

I think this is just another gradation. Something like phone<G7x2<EOS M<Rebel~R series<FF DSLR <medium format. Increases in size, IQ and cost. Pick which suits your purpose.

Grant, there is some new cool tech in the R.
