Well.....
Canon did just file a patent for a TS lens with IS.
I won't be shocked by non-L glass in the RF mount. I will be pleasantly surprised if any of those lenses are remotely as cheap as their EF counterparts. I doubt we will ever see any RF glass such as a sub-$500 85/1.8, 100/2, or 24/2.8. We may see a 50/1.8 or 35/2 below $500, but they'll be priced closer to $500 than to the $150 EF50mm f/1.8 STM.
For all practical purposes, the MP-E 65mm 1-5X Macro is a zoom lens. Since it can not focus collimated light anywhere behind the lens' rear element, there's no real way to express it's "actual" focal length, which is measured by how far behind the rear nodal point collimated light (light coming from a distance of infinity) is brought to focus.
At 1X it gives the same angle of view (AoV) as a theoretical 65mm single element thin lens lens focused at unity (1:1 magnification) which is equivalent to the AoV provided by a 130mm lens focused at infinity.
At 5X it gives the same AoV as a theoretical 325mm single element thin lens focused at unity, which is equivalent to the AoV provided by a 650mm lens focused at infinity.
Which is exactly why I made the suggestion above that consumer glass in the RF mount is DOA. Adapted EF lenses are "good enough" for those who desire "price/performance" or "size/performance" instead of "absolute image quality" no matter what the price.
The RF 35mm f/1.8 IS is the "nifty fifty" of the shorter RF registration distance. 35mm is the design "sweet spot" for a FF sensor with a 43mm diagonal and a 20mm registration distance the same way 50mm is for 135 film with a 44mm BFD. $450 for the RF 35mm f/1.8 IS is a lot more than $150, which is what the EF 50mm f/1.8 STM is currently selling for.
If you think the RF 85/1.8 will be anywhere near as cheap as the EF 85/1.8, you're going to be disappointed. I'd love to be wrong, by the way.
AF speed is also dependent upon available electrical current. That's why many of the same EF lenses will focus a lot faster on, say, a 1D X than on a Rebel SL1. With the smaller batteries in the R bodies, at least at this point, AF with EF lenses that have heavy focusing elements on R bodies will be slower than with EF cameras that use more powerful batteries.
The RF 35mm f/1.8 is the "nifty fifty" for the RF mount with its 20mm registration distance (instead of 44mm for the EF mount). And $450 is 3X what the EF 50mm f/1.8 is selling for these days. Will the RF system have non-L lenses? Certainly. Will they have a wide range of sub $500 primes like EF does: 24/2.8, 35/2, 50/1.8, 85/1.8, 100/2? Not a chance. Those interested in sub $500 lenses already have the EF versions and are mostly happy to keep them to use on both RF and EF-M mount bodies.
I'd love to be wrong, by the way.
Or consumer use existing EF glass on both M and RP.
You seem to be judging the differences between the EF 24-105mm and the RF 24-105mm based strictly on "spec sheet" and measurement of performance when imaging flat test charts at relatively short distances. Have you actually gotten out and shot with the RF 24-105mm in real world scenarios?
Yeah, I'd really like to see the 5D Mark V as soon as possible. Not because I'd buy one, but I'd like to get a 5D mark IV after the price drops.
I don't consider $700-1000 "consumer level." That's the lower half of "mid-grade" ($700-1500) in my mind. To me "consumer level" is sub $600 ala the 85/1.8, 100/2, 35/2, non-L 100/2.8 Macro, etc.
