New EF-S 11-24mm f/3.5-4.5 patent by Canon

patent canon replace,ment

Google filed as new patent for a lens with focal length 11.61-15.50-24.07mm. This upcoming lens resembles the EF-S 10-22mm f/3.5-4.5 lens which is placed among the best lenses according to customer reviews. Hence we may expect this new lens as the replacement for the 10-22mm. Few things that we’d love to see in the new lenses include a STM and a lens body made up of tad higher quality material.

Patent info. (Google translated):
