Another Canon patent for an interesting optical for mule, a EF 28-560mm f/2.8-5.6 lens for full-frame sensors. That’s a 20x zoom, and I can’t help but have to think about some compact, mirrorless full-frame camera :-)
A Canon patent for what appears to be another possible kit lens for the [shoplink 6091]EOS M[/shoplink] system, a EF-M 15-50mm f/3.5-5.6 IS STM lens.
I do not think Canon will release another kit lens for the EOS M, after the [shoplink 6095]EF-M 18-55mm f/3.5-5.6 IS STM[/shoplink] and the newer [shoplink 38577]EF-M 15-45mm f/3.5-6.3 IS STM[/shoplink]. Guess this is one of the many patents that never will hit the market.
Another Canon patent for a Cinema lens, a CN-E 30-160mm f/ 2.8 LS. This optical formula formula refers to a Super35mm sensor, i.e. the sensor used in Canon’s Cinema line-up.
Canon patent for a 50-300mm F4.5-5.6 lens with diffractive optical elements. The optic formula described in the patent appears to refer to APS-C sensor (not full-frame). Hence, the lens may come either for EF-S or EF-M mount. I guess this would be the first APC-S oriented lens with diffractive optics (anyone?).
The more a DSLR is build to last, i.e. is made of metal instead of plastic, the more difficult it gets to add radio devices like GPS or WiFi. This is something Canon explained often.
This Canon patent appears to show a solution for the issue. The GPS module is placed on top of the camera body, where usually the pop-up flash is located. That’s where the Canon [shoplink 37157]EOS-1D X Mark II[/shoplink] has the GPS device. The patent does not explicitly mention WiFi but I think it is safe to assume the solution described in the patent would work for WiFi too.
It may be that the patent points to something that has to do with the upcoming EOS 5D Mark IV, which, as it was anticipated first on CW, will most likely have GPS and WiFi on board.
