Canon Patent For 1.4x Extender (Updated)

400

I made a big mistake reading the patent. Thanks to DicaHub I can correct it. The patent is not for a 400mm lens with built-in extender, but for a 1.4x extender for lenses that do not support contrast AF. With such lenses a “wobbling” effect can appear when shooting video. The patent refers to an extender with movable elements to suppress the “wobbling” effect.

Egami (translated) spotted another patent filed by Canon, this time for a 400mm lens with built-in 1.4x extender.
