We've been told that some “crazy” lenses were coming to the RF mount, and here's a patent uncovered by Northlight that fits the bill.
Canon appears to be working on a fast portrait zoom for the RF mount, with the fastest of the bunch being an RF 50-80mm f/1.1. The number of lens elements in the lens design is remarkable.
Canon RF 50-80mm f/1.1:
- Focal length: 51.50mm 64.17mm 82.52mm
- F-number: 1.13 1.13 1.13
- Half angle of view: 22.79° – 18.63° – 14.69°
- Total lens length 220.20mm 225.05mm 224.20mm
- BF 6.51mm 6.53mm 8.64mm
Also included in this patent are optical formulas for a RF 50-80mm f/1.2, RF 50-80mm f/1.4, RF 50-80mm f/1.6 and a RF 50-80mm f/1.8.
We expect some new lens designs to be announced in the first half of 2020. Keep in mind, just because there's a patent, doesn't mean we'll actually see this as a product.

I don't understand the idea of making similar lenses. Just make one 50-80mm f1.2. Marketing I guess...$$$
What Canon does to try and occupy some of the 'high ground' in this rapidly changing market will be interesting to see over the next few years.
But hey, the 90D is on its way to keep some of the masses happy (as if)
Remember that a patent application does not equal a new product.
Again, a EOS R pro body, better or equivalent to a7riv, should be the highest priority.
Repeat after me:
Patent applications are about possible designs, not products
Patent applications are about possible designs, not products
Patent applications are about possible designs, not products

I bet they work on all sorts of weird designs and end up patenting things which have elements which could eventually be of value. I'm actually curious about what ideas hit the cutting room floor.
It's stuff like this that creates a certain mystic about a brand; though I do note though that an 8 inch lens is not going to be discrete.
MP-E 65mm f2.8 Macro?
EF 8-15mm f4L Fisheye?
Speedlite 470EX-AI?
These don't count as innovative, radical or futuristic?
This is why I have an answer when some people ask why I 'still' use Canon cameras ;-)
