Canon Patent For Superfast Prime Lenses For The EOS R System
If we believe the sheer number of Canon patent applications for RF lenses we must think Canon takes their EOS R full frame mirrorless system very seriously.
Canon patent application 2019-197095A (Japan) discusses the optical formulas for three very fast prime lenses for the RF mount. The lenses are 18 mm f/1, 18mm f/1.2, and 25mm f/1.2.
- Focal length: 18.51mm
- F no: 1.24
- ω : 49.45
- Image height: 21.64mm
- Lens length: 129.00mm
- Back focus: 16.40mm
- Focal length: 24.59mm
- F no: 1.24
- ω : 41.35
- Image height: 21.64mm
- Lens length: 129.01mm
- Back focus: 13.57mm
- Focal length: 18.50mm
- F no: 1.03
- ω : 49.47
- Image height: 21.64mm
- Lens length: 150.00mm
- Back focus: 4.99mm
Don’t expect these lenses to be announced anytime soon.
