Patent: Canon EF 24-300mm f/3.5-5.6

By Canon Rumors | January 3, 2016 | Canon Patents

Another patent for a full frame superzoom has appeared from Canon. We’ve written about the development of such a lens a few times since May of 2015, most recently this past November, and we continue to see more patents for such a lens.

Patent Publication No. 2015-215438 (Machine Translated)

Published 2015.12.3

Filing date 2014.5.9

Focal length 24.70 101.33 292.01

Fno 3.50 4.59 5.87

ω (degrees) 41.22 12.05 4.24

Image height 21.64 21.64 21.64

Overall length of the lens 202.71 232.50 288.71

BF 38.78 43.69 75.66

I think it’s safe to say we’ll be getting a new full frame superzoom in some form in the near future.
