New Rumor: Another RF F2.0 zoom on it's way from Canon

Another lens rumor has surfaced, and this time, Canon Rumors states that a new F2.0 zoom is in the making from Canon.  This lens would be the second of a F2.0 holy trinity of lenses.  The trinity of professional lenses is usually an ultra wide zoom, normal zoom and telephoto zoom, all with the same maximum aperture.  For instance, the 15-35L F2.8, 24-70L F2.8 and the 70-200L F2.8 are all upcoming Canon RF lenses that would be considered the F2.8 trinity.

How realistic is this? Well an F2.0 70-200 is not realistic. it would be around the size of the Canon EF 200mm F2.0L and cost around the same.  That's clearly not happening in our lifetimes.

Way back in May 2018, we discovered this patent application from Canon, with a 70-120mm F2.0 zoom.  From that patent application, we see an embodiment with;

Focal distance      72.00 114.84 146.00  92.60 123.41 
F number             2.06   2.06   2.06   2.06   2.06 
a half field angle  16.72  10.67   8.43  13.15   9.94 
Image height        21.64   21.64  21.64 21.64  21.64 
Whole length       210.32 210.32 210.32 210.32 210.32 
BF                  21.80  21.80 21.80   21.80  21.80 

Which appears to have an internal zoom, and a back focus distance very similar to that of the RF mount.  Certainly showing that Canon has been working on this RF stuff for a while now. 

Could this be the lens that is coming out?  That would pretty much "almost" take the F2.0 lenses up to all the normal professional prime lenses from 24mm to nearly 135mm in two zooms with a focal range of 28 to 125mm.  If this patent application isn't it, then I would surmise that something like a 70-135mm would make a lot of sense.

Time will tell, but it was interesting to look back through some of the earlier patent applications that we discovered that are now coming more to light than when they were discovered.
