for me, too little, too late
Sorry, Canon.
This looks like a great camera,with most of the features I need in a small, light package. I'm not sure how many lenses there are for this, when I sold my original "M" there were only 3 system lenses.(I don't count adapted lenses)
After 30 years of using Canon SLRS/DSLRS, I sold most of my lenses, and kept the two bodies(60,70d)I had since they fetched little on the market. I am now fully invested in the Panasonic Lumix m43 system.
I had no complaints about Canon ergonomics or IQ, none at all. However, weight and size became more of a factor every year. If Canon had developed an M system faster, including long zoom lenses, I probably would have stayed. Frankly, Panasonic Mirrorless are harder to use if you like making a lot of adjustments. However, I have reduced the weight factor 50% from the DSLRs, which is a load off when I go on a hike or nature walk.
As far as IQ, well, I really see no difference in noise up to 1200 ISO, or resolution. I'm not saying there IS no difference, just that I'm not seeing it, even on A3 prints. Obviously still check Canon Rumors once in a while, and if a friend is intent on a DSLR, I recommend Canon. However, the axiom that the "Best camera is the camera that you have with you" means I have no regrets about lightening up with the Lumix system.
