I have reported many times about a small and affordable Canon RF 100-400mm zoom lens, and another patent for such an optical formula has appeared.
Canon RF 100-400mm f/5-7.1 IS USM
Focal length: 103.00mm 200.00mm 388.50mm
F-number: 5.00 6.26 7.10
Half angle of view: 11.86° 6.17° 3.19°
Image height: 21.64mm 21.64mm 21.64mm
Lens overall length: 215.58mm 255.38mm 293.58mm
Backfocus: 38.40mm 58.61mm 78.01mm
This lens has been on our RF lens roadmap for quite some time, but is listed as an RF 100-400mm f/5.6-7.1 IS USM. It will obviously be small, lightweight, and quite affordable when compared to the RF 100-500mm f/4.5-7.1L IS USM
An RF 100-400mm lens has also appeared internally at...
