Dont get me wrong, the bodies look great and while being a little expensive have all the right specs
But the two RF-S lenses they launched with tell me everything I need to know about this system. I would not buy into RF-S if the lenses you want aren't in the lineup right now, because between
- Canon's history of crop system lens development (though EF-M was better than people give credit for)
- The guaranteed smaller user base of RF-S limiting ROI
- FF RF's overall lens trajectory
- Canon completely locking down RF from third party companies (no Viltrox, no Sigma, no Tamron, no Samyang to the rescue)
the chances of getting anything beyond these laughably slow kit lenses are slim to none IMO.
These bodies should have been on the EF-M mount, along with 2 enthusiast grade standard zooms (14-80 2.8-4, 15-55 2.8). So now Canon has one crop MILC system with a huge user base and 4-5 pieces of gear from completion that they've given up on, and an all new system with no users, cheap or FF lenses, and questionable future prospects for investment and development.
And while the R7 has the photographic specs of a modern 7D, from what I've seen it's nowhere near as rugged as 7Ds used to be which I imagine will be an issue for wildlife shooters.
What is the point of RF-S?
