Oh yes folks, Canon is really going crazy with the super fast RF lenses. There is a brand newly published japanese patent describing the specs of new f/1.0 and f/1.2 RF lenses:
18mm f/1.2 lens specs:
Focal length: 18.51 mm
F no: 1.24
ω : 49.45
Image height: 21.64 mm
Lens length: 129.00 mm
Back focus: 16.40 mm
25mm f/1.2 lens specs:
Focal length: 24.59 mm
F no: 1.24
ω : 41.35
Image height: 21.64 mm
Lens length: 129.01 mm
Back focus: 13.57 mm
18mm f/1.0 lens specs:
Focal length: 18.50 mm
F no: 1.03
ω : 49.47
Image height: 21.64 mm
Lens length: 150.00 mm
Back focus: 4.99 mm
Now we all know the patent world is a parallel universe of possibilities that might not be realized in our simple 11 dimensional universe (according to string theory). And particularly this 18mm f/1.0 lens really sounds out of this world! If they make it I will jump for joy naked in front of the Canon Tokyo headquarters! And that might be a good reason for them to not make it at all :)
