I had this buried on a poll thread and thought it might get lost.
A few folks here offered this EF-X idea and I put it to pictures. Forgive my crappy Photoshoppery here, but would this idea work?
Pros:
Cons:
This is not my idea -- Don Haines (and some others, forgive my poor memory) first brought it to my attention. I'm just curious to see how technically viable this is, as well as how this might be received by the 'I want it thin' FF mirrorless camp.

A few folks here offered this EF-X idea and I put it to pictures. Forgive my crappy Photoshoppery here, but would this idea work?
Pros:
- Full EF mirrorless = no adaptors needed, no one gets cold feet about Canon abandoning them, etc.
- A tiny lens + body combination is still possible
- Limited scope for Canon to support. It would be impractical to do this for larger / longer / faster glass, so Canon won't have to build a houseloud of these EF-X lenses -- they'd likely just keep this to the 3-7 lenses that make the size savings pop, like the 28 f/2.8 IS I show in the graphic.
Cons:
- Say arrivederci to adapting FD, EF-S (in crop mode), Nikkor, and third party lenses.
- These lenses might have to protrude into the mirror-space a lot to enjoy that small overall footprint, like a good 20-25mm or so, so I wonder if that means we're dealing with a collapsing lens + FBW sort of 'powered' mounting process. (Not sure this is a 'con' or just what's needed to implement this idea.)
- A nestled smaller lens might have very little sticking out (see pic below), which will certainly reduce the real estate for focus rings, zoom rings, distance scales, AF + IS switches, etc. and reversing appropriately sized hoods may no longer be possible.
- The full EF tube/block = no chance for an ultra-slim deck of cards / portable hard drive sized tiny 2nd body for travel.
- Large aperture rear elements could be problematic to nestle like this, ya? (But they might never make fast glass that would be too big in this format -- possibly just point folks to EF at that point.)
This is not my idea -- Don Haines (and some others, forgive my poor memory) first brought it to my attention. I'm just curious to see how technically viable this is, as well as how this might be received by the 'I want it thin' FF mirrorless camp.
