Canon Patent Application: Canon RF 10-24mm F4.0

It seems like it's an ultra wide angle patent day today, as we have discovered another patent, this one for an incredible 10-24mm F4.0, for yes, full frame RF cameras.

Just when you thought the Canon EF 11-24mm F4.0 was wide, Canon is stating, "hold my beer" with this patent application.

Lens Data:

Focal length 10.30 14.94 23.30  
F-number 4.12 4.12 4.12  
Half angle of view (degrees) 64.54 55.38 42.88  
Image height 21.64 21.64 21.64  
Total lens length 156.50 145.83 144.37  
BF 12.00 12.00 12.00  
 

Of course there's one slight niggle with this patent application, and that is that the back focus is a little close, however still doable for the RF mount.

Also included in this patent application, is a much easier to implement 10-24mm lens with a more relaxed back focus distance.
