Canon EOS 7D Replacement NDAs To Expire Early September

Canon EOS 7D Replacement

Fake EOS 7D Mark II (mock-up)

I (thanks) and others have been notified that the NDAs (non disclosure agreements) for the EOS 7D replacement will expire early September.

CR speculates the dates could be either September 9 (Tuesday) or September 12 (Friday), 2014. They also got rumor that a new telephoto lens could be announced along with the EOS 7D replacement.

I always thought that the rumored announcement date in August was a bit weird. It’s hard to differentiate serious rumors from the rest. Photokina 2014 starts September 16, 2014, so an announcement during the first weeks of September makes sense.

Canon Patent For 1.4x Extender (Updated)


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.
