<p>According to an interview with Mr Makoto Sakaeta Masaya, the managing director of Canon Image Communication Business Division. Canon is exploring the possibility of a new lens mount. I suspect its application would be for a full frame mirrorless system of some kind.</p>
in no place in this interview was full frame mentioned - just the reverse - the intent of the interview was that things should be made smaller - such as 1" sensor / m43's as the quality of those sensors improve.
not to mention the current EF-M throat dimension once you remove the baffling can already support a full frame sensor.
full frame doesn't do anything for the miniturization of the "system" which is what Masaya was talking about.
everyone's running amok on this thread - and there's no indication whatsoever that canon's making a bigger than APS-C MILC.
(the only thing that would make sense for bigger than APS-C would be medium format)
One possibility would be as I mentioned that Sony by shoehorning FF lenses into a mount ment for ASPC lenses has actually compromised its FE system.
Again look at the RX1 one lens design with the massive rear element...
Maybe FF mirrorless size saving would be greater with a larger mount that can allow such big rear elements to avoid issues with light dropoff and boarder softness?
I'd agree people have run riot with any idea of FF mirrorless but I wouldn't say its impossible, beyond the above point remember of course that the EF-M system is quite limited anyway so linking it to a FF mirrorless one wouldn't really matter that much. Personally I see relatively little benefit of linking even the larger E-mount system, all the FE lenses are large an expensive and don't see like something an ASPC user would buy unlike the EF mount that offers quite a few lenses attractive to ASPC users,
Besides that and MF another possibility I spose is a system more like the Nikon 1 and targeting it with lenses like the new 70-300mm Nikon have just released as a small action/wildlife camera.
