But I just can't see them signing up to FD --> EF 2.0.  New lenses for mirrorless would happen with a thin mount (of course), but not a rebuild of EF for mirrorless -- there's no chance of that until all the mirrorslappers retire their mirrors.

With dSLRs accounting for 65% of the ILC market, the demise of the reflex mirror is still a long way off...and by the time it happens, it may not be the current version of MILCs, but an industry paradigm shift that supplants today's ILCs (think: light field cameras, multi-lens 'bug-eye' cameras, holography, etc.).

Compact lenses? Here we have the Canon 35mm f1.4L to the left and the Leica M 35mm f1.4 Summilux ASPH to the right. Both fantastic, full frame, lenses. Adding AF to the Leica would grow it a bit, but still ...

Awesome, but what does pulling the mirror have to do with that example? 

I appreciate the M mount is mirrorless, but why couldn't Canon make tiny FF lenses for SLRs while it was at it?  If they did, it would just be 1" smaller in your bag with mirrorless than SLR.

I'm not saying you can't make a great small lens.  But if mirrorless' greatest virtue only really pops if mirrorless is given special things SLRs don't get, how special really is mirrorless?

I don´t pretend to know anything about lens design. However, I am a bit puzzled by the fact that Leica are making these fantastic prime lenses, like the 35/1.4 or 50/1.4 Summilux lenses, in such a small package, while their DSLR counterparts are huge in comparison. Can anyone explain why a DSLR lens have to be that much bigger?

+1.  Anyone who claims that mirrorless could be soooo tiny if we only had manual f/5.6 primes, if we only had collapsible/telescoping lenses like compacts, if Canon only 'took some fat' out of some optical designs and optimized things for smallest physical length, etc. is missing the point.  SLRs could do that, too.

So we're hemming and hawing about whether Canon will jump the shark and fully rebuild the EF portfolio for the opportunity of taking up one. less. inch. in your bag.  It's simply not going to happen
 
That doesn't mean a thin FF mirrorless mount + adaptor won't happen -- I'm just saying that it might offer 3-5 key mirrorless mount lenses in the first few years and that would be it.  Even if FF mirrorless does very well commercially, letting more and more EF creature comfort lenses fall into the new mount is a slippery slope.     

- A

One key question, it seems to me, is how small Canon could make a mirrorless FF camera with an EF mount.  At this point, I would think that Canon has an answer to this question.  Canon isn't going to introduce an EF-X mount unless they are very sure that they want to go someplace they can't get to with an EF mount. To me, it seems very likely that Canon's first FF mirrorless will have an EF mount.

Fair point.  Of course, the Leica is rather costly...and has a manual aperture (so two missing motors).  But it does show that a compact fast prime is possible (actually, it has been for a while, looking back at some old Canon lenses, like their S-monut 35/1.5 that was similar in size to the Leica 35/1.4, or their 50/0.95 that was the same physical length as the Leica 35/1.4 albeit quite a bit fatter, but f/0.95 will do that ;) ).

As soon as you move to a 50mm sensor then Mirrorless has obvious size advantages.

Really someone “could” be making a pocketable mirrorless body.
Looking at what they’re doing with cellphones I bet someone “could” make a 10mm thick ILC body and some 5mm thick lenses, that would fit pretty firmly in the “pocketable” category, but practical reality dictates no-one wants to make that many compromises for size.

Right now Mirrorless basically exists for video.

Perhaps, at least in part, it's the microlens design of the sensor.  With the Leica 35/1.4, the rear element of the lens is actually recessed into the body when mounted (like some Canon EF-S lenses), and whereas Sony seems to have issues with high IQ from lenses with a very short sensor-to-rear-element distance, Leica uses a microlens/pixel design (greater microlens curvature, shallower pixel wells; right image below) that compensates for the high incident light angles you get when the lens is so close to the sensor.

If, and that’s a big one, canon makes a new full frame mount without the mirror-defined flange distance, I’d expect them to end full frame EF lens development and slow/eventually end full frame EF lens production.

End lens development for a platform comprising 2/3 of the ILC market?   ???

Yes, given the above if:

“If Canon believes they will generate more profit selling new-mount lenses and adapters than EF lenses going forward”

Agree, actually.  But Canon couldn't possibly believe the 'if' clause above.  Here is the list of Pros for migrating from EF to EF-mirrorless:

  • A handful of smaller lenses (say 10-20% of the current EF portfolio) could lead to a nontrivially smaller body + lens combination

  • [...crickets...]

And the Cons list looks like what would happen if a black hole for all resources and product development consumed your company for 10+ years.

Unless you want to talk about a major tectonic delta in lens design to support curved sensors, every lens will be a compact telescoping/collapsible design, they start to offer leaf shutter lenses, etc., rebuilding all/most of EF into mirrorless FF lenses is a colossal waste of time and money when you consider the very meager pickings on the Pros list above.

- A

Something in what you said gave me an idea. How about a short mount where you need an adapter to use EF lenses, but the adapter has a leaf shutter, so suddenly all EF lenses now are leaf shutter lenses. Would that be interesting (or possible)?

That may help. On the other hand, you can use Leica lenses that are several decades old, so they are at least not designed for a digital sensor.

Inside that adapter is not all too far away from the sensor and would just cause a great amount of vignetting. A leaf shutter has to be located right next to the aperture in the lens.

That's the advantage of the Leica sensor design – lenses with lower incident light angles work just fine (as they do on typical sensors), but so do those with higher angles.  But with a rangefinger history, shorter backfocus distances were historically common – those short Canon S-mount lenses I mentioned were for rangefinders, too.

A retrofocus design will make the lens much bigger. Without a mirror, the lens can protrude inside the camera body, and that can lead to smaller wide angle lenses because different lens designs becomes available. Rangefinder always had this advantage.

See for example: https://www.lensrentals.com/blog/2011/03/the-development-of-wide-angle-lenses/

This could be an advantage for mirrorless cameras and lenses, and you don't need to change the mount. For example, some earlier Canon UWA like the FL 19/3.5 required to lock the mirror because of the protruding element - but it was quite compact when mounted, alike a pancake (later a retrofocus one was made available). The Pellix, with its fixed mirror, could also use some specific small lens because the mirror didn't need space to move.

A mirrorless with EF mount could use this kind of lenses to keep them smaller, of course they couldn't be mounted on an EF SLR.

I am quite invested in Quality glass, not as extreme as maybe others, and use my FF System as a Hobbyist (with chronically lack of time)

When buying my equipment, i assumed that glass would Keep it's value better than other consumer products, so i spent money easier (i can sell a lens if i dont use it enough)

Now i have a Smartphone as well and not the need to carry the big camera all the time, so take part of my photos with the phone and if i try be serious with the DSLR.

If Canon now presents a new Mount and it is expected that over some period the DSLR's get replaced my Mirrorless with a new mount, this will very fast reduce the value of my Investment so i had to decide if i should

a) Keep on the old System
b) move soon and sell my old gear in short term
c) or if i postpone the move and sell my lensess at a time when they are woth almost nothing

on a) i must Forget about all my Money and use my equipment, knowing that it will get passed by the developpment and after some time i have no longer competitive Equipment

on b) i must spend lot of Money in short term, replaplace the camera(s) soon and the lenses soon after equivalents came out.

on c) i live with Adapters for a long time and accept a big loss on my lenses which nobody wants anymorwe, after they have obsolet for a longer time already.

So, all 3 ways are so frustrating, that leaving the hobby is a valuable option, rely on the phone and maybe buy a better compact (on 1'', mft or apsc basis) camera.

i think the FD to EF Transition was similarely painful, but then one got a fast development, autofocus, better Flash Systems etc. Now DSLR to Mirrorless gives much fewer benefit in comparision, so abandonning the Mount is very dangerous, they can put many customers into frustration. This especially as there are still coming high value lenses on the market, which are not ment to be used 4 years only.

AND, as many times written already, "small" will be only very few combinations, and not the bundles i usually see FF cameras used with. Combined with a 16-35 & 24-70 & 70-200 2.8 lens trio, 20mm gain in thickness doesnt matter at all.

If there are other benefits, as faster FPS for example, then a Mirrorless camera can make sense, but please it should support my lens collection.

My guess is that it will be quite a while before you are faced with unpleasant choices created by the collapse of the value of EF lenses and related equipment.  For the reasons you describe, I think Canon will continue to make EF cameras because people will continue to buy them.

well again, this site reported on such rumors.

Seems you don't understand what the word 'rumor' means.

ru·mor   ˈro͞omər   noun
1. a currently circulating story or report of uncertain or doubtful truth.

If you're looking for canonfacts.com, you're in the wrong place – check out Canon's press release page.  The rumors reported here are wrong far more often then they're right.


Are you saying canon RD cannot make an adapter as a means to exploit a potential new market?

No, you said that.  According to you, that's why Canon and Nikon haven't released a FF MILC.  Please, quit while you're behind and before you embarrass yourself further.
