Egami (translated) spotted a patent filed by Canon for a motorized mirror return mechanism. The advantages of such a mirror system are less vibration, and the possibility to miniaturize the whole thing. The solution described in the patent opens the way for a DSLR that is smaller than the Canon Rebel SL1/EOS 100D. The drawback is that such a mechanism can not achieve the same fps rate as classic mirror mechanism.

  • (Axis of the spiral on the motor shaft) lead screw
  • Quick return mirror that moves with the rotation of the lead screw

   

Back in October Egami (translated) spotted a pretty interesting patent filed by Canon: an adapter for the EOS M system that not only can be used to attach lenses with a different mount type (back-focus), but also has an accessory shoe and can get a grip attached to. WOW! What’s that?

Is this for the pro-oriented EOS M camera that is rumored? The patent was filed in April 2012. I am curious if this piece of gear will ever hit the shelves. This adapter would open a world of possibilities on the EOS M system, especially because of the accessory shoe which could accommodate an EVF (?), or an external microphone. I guess the grip will be useful with big lenses attached to. Looking at the pic below it seems as if a battery pack is attached to the adapter.

The Canon EOS 70D is not the end of the story.

Egami (translated) spotted a patent filed by Canon that looks to be the next step in Canon’s Dual Pixel CMOS Auto-Focus technology. The patent appears to refer to a more sensitive Dual Pixel AF.

Egami (translated) spotted a pretty interesting patent filed by Canon. The patent refers to a transparent mirror technology (aka pellicle mirror), the technology Sony employes on their SLT cameras. This could be a hint about what Canon’s engineers are working on.

  • Publication date 2013.10.24
  • Filing date 2012.4.12
• Canon patent
  • Pellicle mirror

  • Reflectance (transmittance) variable
  • (Low transmittance) high set the reflectance OVF when, at the time of imaging is set (high transmittance) low reflectance
