Canon Patent Application: Canon RF 24-80 F4.0

Buried in one of the (many) Canon RF 24-105 patents that I've come across was another interesting design that deserved some notice.

Here Canon is also patenting a Canon RF 24-80mm F4 lens that would be a welcomed addition to the Canon RF lens portfolio.

Since Nikon has rounded out a F4 zoom set, you can rest assured that Canon will come out with one as well.

The lens particulars;

focal length 24.72 48.09 82.45
F number 4.12 4.12 4.12
Half angle of view ( 41.19 24.22 14.70
Image height 21.64 21.64 21.64
Total lens length 119.50 134.52 149.55
BF 13.50 18.71 22.73

Also included, but a lens that would probably never see the light of day, considering the 24-105L was already released, is a 24-130mm F4.0

focal length 24.72 63.46 131.00
F-number 4.12 4.12 4.12
Half angle of view (degree) 41.19 18.83 9.38

Total lens length 137.50 168.92 200.33
BF 13.50 24.03 28.27
