Canon's technology reserve is so strong that it recently announced six lens patents, which are basically concentrated in wide-angle zoom.

Canon releases 6 RF camera lens patents


The six lens are: Canon RF 15-35mm f/2.8L、Canon RF 17-70mm f/3.5-5.6、Canon RF 15-35mm f/4L、Canon RF 16-35 f/4L、Canon RF 14-40mm f/4L、Canon RF 16-40mm f/4L. Like 14-40mm and 16-40mm, the former is only 2 mm wide, so we need to distinguish two lenses. It is clear that Canon knows exactly what the photographer needs to refine before doing so. For example, a factory designed 28-75 and 24-70 ternary lenses at the same time, which looks like the focal length is similar, but the former is cheaper than the latter, and the former has the same market demand.
