Well here's a fun optical formula from Canon discovered by Canon News, a Canon RF 135mm f/1.4L USM. The Canon EF 135mm f/2L USM is an all-time classic, and this would certainly be an amazing offering worth of the new lens mount.
I think there is a higher than normal probability that such a lens design will make it into a consumer product.
Canon RF 135mm f/1.4L USM:
- Focal length: 131.00mm
- F-Number: 1.41
- Half angle of view: 9.38°
- Image height: 21.64mm
- Total lens length: 182.28mm
- BF: 13.87mm
