Canon Patent Application: Canon RF 8-15mm F4.0 Fisheye One of Canon's more unique lenses for the EF mount is the Canon EF 8-15mm Zoom fisheye lens. It appears that Canon feels it should be repeated on the RF mount as well. This patent application describes a fisheye lens with a zoom from 8mm to 15mm. With a distinctly short backfocus distance, this is certainly for the mirrorless mount. One of the embodiments is shown below; focal length 8.10 11.97 15.07 F number 4.10 4.10 4.10 Half angle of view 91.51 90.00 90.32 Image height 11.50 17.00 21.50 Lens total length 111.33 107.33 108.91 BF 13.13 24.44 31.63 Japan Patent Application 2020-166234 Related articles Patent Application: Canon RF-S14-30mm F4-6.3 IS STM PZ Canon Patent: Quarter Wave Element Lenses Canon Patent: Esoteric Optical Designs Canon Patent: 17-70 and 16-60mm F2.8 Zooms Canon Patent Application: More Fast RF VCM Primes Previous Article New Rumor: Canon has developed a new full frame global shutter sensor Next Article New Rumor: Canon's 2021 lens roadmap Print Tags: Patent Application Please login or register to post comments.
