if ML was fully endorsed by Canon, a much higher percentage of Canon owners would probably install it on their Canon cameras.

I for one would never put unsupported third-party firmware on any electronic device. Especially not, when I am told by the manufacturer that it voids warranty on the product. And I also do not open iPhones oder disassemble Canon cameras physically. I am not Roger Cicala .. I would not get it back together and working again.   ;D

And I guess the majority of Canon users handles it the same way.

You could do it with MagicLantern's DualISO feature.

maybe. But with no current Canon camera ... running original firmware on it.
And even with ML it would not have 36 MP (base) resolution.  ;D

Just to make sure: it is not my image, i just posted the link.

"DR is overrated, only poor photographers underexpose severely and then have to pull up shadows, Canon is best, Sony A7/R are just toys, show me real life imags where more DR really ic critical", ...
 yada yada yada  ;D

here you go! Just dig the image "Dali's dream" by amazing photogpraher Erez Marom:

I took the image with my Sony A7R and my Canon 16-35mm f/2.8L II lens. I wanted as wide an angle as I could, so I shot at 16mm. The exposure time was 0.6 sec at ISO 100.

Before looking at the RAW images, let's mention the second important aspect. It's very easy to see that the images are strongly underexposed. The reason is that the specific sensor I used, that of the Sony A7R, has tremendous dynamic range, and holds an amazing amount of detail in the darker pixels. I could therefore expose 'to the left', maintaining good detail in the light areas, and brighten the shadows in post processing without compromising quality and without the use of HDR, which would be difficult to do with the hard contrast in this scene. Let's look at the RAW images. Yes, they are very dark. But based on my familiarity with the A7R sensor, I knew I'd be able to extract perfect color and detail from the dark areas. Praise Sony!

Really like the "magic finger trick" Erez Marom demonstrates here! THUMBS UP! :)

* 7D II is a game-changer, proof .. a professional weather sealed sports camera with a professional frame rate and professional auto focus system can be put into a compact body costing under $2k which is 50-75% less than previous cameras with similar functionality.

no. It costs 100% of the preceding 7D, which has already proven that point and was "borderline game-changing", when it came out in 2009. 

Basically something labeled Mk. II or III by Canon rarely is a game-changer. Exception so far: 5D II for video. ;-)

I will upgrade to a 7D II if it can fully match an upcoming Nikon D400. In terms of sensor/IQ, electronics, performance/responsiveness, and especially AF ... most likely that would mean the 7D II should "inherit" the current 1D IV AF system (45 pt). In addition I would like it to get a tilt-swivel display (like the 60D). If they offer such a camera at $ 1800 launch price it will sell extremely well again and will leave hardly ny room or need for a  70D.
I can't say that I know how good or bad the Nikon D400 is (if it exists), but your statement above indicates that the 7D Mark II should be good enough for your standards. You even guessed correct on the price.

Look at the date of that posting. had Canon come out with the 7D II in spring of 2013, I would have bought it.
But now we are at the end of 2014. I am clear, I want an FF sensored cam and I want it without a mirror.

7D II is certainly a fine DSLR, and iw welll worth it, if one is into reach-limited tele-focused action-oriented Phtoography .. or possibly astrophotography. But I do not see anything that deserves the the word "game changing".  Yes, it is an improvement, but in the grand scheme of things it is just another minor iteration of the Canon APS-C mirrorslapper series and their 18/20 MP sensors.

To me ... a "game cahnging product is "proff of some concept, that was considered hard, if not imposible to achieve.

Canon game cahngers in my book:
* 1D ... proof of concept, of a "fully viable professional grade digital camera, offering more than what 135 film ever could.
* Digital Rebel/300D - proof of concept, that digital DSLRs can be offered at "reasonable cost" (sub USD 1000), within reach of consumers/enthusiasts.
* 5D was a game changer - proof, that FF sensored  DSLRs can be built "at reasonable cost" and first time they really came into reach of enthusiasts and semi-pros.
* 5D II was a game-changer, proof .. HD video can be done with a DSLR; put "shallow field of depth" capability into hands of video entghusiasts, low budget film makers

Since then I have not seen any game-changing cameras from Canon, only iterations, comparatively minor improvements.
* Sony A7/R/S are game-changers. Proof of concept, that the best, full-blown FF sensors on the market can be put into a body as small as an mFT or APS-C camera. Deemed impossible by many beforehand. ANd passin on some of the cost savings possible with cheaper to built mirrorless cams to the customers.

Let's see, what comes next that truly deserves the badge "game changing".

I think that's what Sony was gunning for with the RX1.  I know it lacked a proper rangefinder OVF, but a $2,800 (at release) fixed lens camera was nothing if not a luxury item.

Exactly. Epic fail. Deservedly so. Even nouveau-riche russians and saudis want a zoom lens on their premium pocket cam. :)

I don't see any reason to be "balanced" if my current supplier delivers subpar product. As in every other business i give them clear warning and tell them what i want. I want the best value for every euro/dollar spent.
14% improvements are ridiculous and utterly meaningless to me (u am not into astro photography).
And What other customers want is totally irrelevant to me as well.

If canon does not deliver FULLY COMPETITIVE products and will stop buying (measure is in effect).
And i will criticize them (measure is in effect).
And buy competitors product. Measure not yet in effect. But will be as soon as somebody meets my requirements. getting closer by the day. Maybe sony a9. :)

No mistake.  There will be a complete transition. Ef-s is the dead end. ;-)

Ef-m = sole surviving aps-c mount
Ef = surviving mount for tele > 100mm
Ef-x = new, dominant mount for mirrorless ff < 100mm.

Advantage for canon: mirrorless ff buyers have to purchase body and new lenses. Bodies cheap, lenses expensive. See sony A7 series plus FE lenses.  ;-)

Hehe, over the next few years you will think a lot about my prediction on how the transition to mirrorless cams will happen at Canon.
It is now so clear to see how things evolve ... but obviously not for everyone.

Well, have fun with mirrorslappers, while it lasts. I don't mind, as long as i get cameras that are a lot smaller, a lot lighter and a lot more capable than anything that could be possibly achieved woth a flapping mirror inside. :)

DSLRs are today where mechanical typewriters were when personal computers moved from IBM XT [APS-C mirrorles] to IBM AT [Sony A7] emerged in the 1980s.  ;D

This is the part where I get lost.  Could the EF-M mount / flange distance / diameter actually support a FF sensor?

Canon has said clearly no. Don't have the link right now, but you can google the interview with a canon exec, i believe it was masaso maeda. It has also been discussed in cr forum a number of times in different threads.

There is no denying, that at the end of the day there will be 3 canon mounts left:
1. ef-m
2. ef-? for ff mirrorless (short flange distance) up to around 100mm focal lengths
3. ef for focal lentghs from about 100mm or 135mm and up - with adapter for mirrorless

There's that damn new FF mirrorless mount again.  As much as it's a clear opportunity in the long term, it's categorically crippling in the near term.  We either have to like adapters or we have to like waiting.  I keep hearing folks say a mount transition would not be that bad -- "we just need a few key lenses" -- but in reality the key lenses each of us want is different and Canon would take 3-5 years to deploy those.

Don't get me wrong -- I want a great mirrorless ecosystem to climb into -- but 'great' is compared to what I have today.  And the options I have today in EF are staggering.

Yes, it will take many years until a full native mirrorless lens range is established.
And yes, using an adaptor is usually less than ideal. BUT - if the adapter comes from Canon and has no optical elements and is included with the FF MILC body, the pain would be eased considerably. It would not have any negative impact on IQ, AF precision, IS functionality, or lens-mount protocol data exchange.

Of course AF-speed might be affected, when non-STM EF lenses, designed for DSLR phase-AF are used via adaptor. But that will provide additional incentive to buy those new, smaller, faster AF, native mirrorless lenses. Good for Canon at least. ;)

I do not really mind using the clever little Canon EF/EF-M adapter to put EF-S and EF lenses with STM AF drive onto my EOS M. I especially like the design of the tripod foot on it. It allows mounting of the camera with any lens to a tripod head/clamp - not only lenses with tripod collar. And it can easily be removed and the foot is very small, but still solid.

My guess is that a FF Mirrorless Canon camera could be about the same size as the Sony A6000, except a little taller to accommodate the larger diameter of the EF mount.

I don't think a Canon FF mirrorless cam [with built-in EVF] could be made as small as Sony A6000.

I'd expect the now vaguley rumored "rangefinder-style" Canon FF MILC ... "EOS X1"  :)  ... to be sized between Sony A7 II [in terms of handgrip size] and Leica M / Fujifilm X-Pro1.

http://camerasize.com/compact/#535,579,389,258,380,ha,t

A solidly constructed and built body of this size, coming in at 600 grams [thanks to MgAl alloys] - with handgrip about the size of Sony A7 II - would give enough support to shoot handheld with adapted Canon L teles up to and including EF 300/2.8 II ... "in a pinch". It would not be as comfortable however, as a 300/2.8 II on a 1D-X sized DSLR body. [Lenses longer/larger/heavier typically are not operated handheld , certainly not over extended periods of time.]

Note that in Japan, the EOS M2 is sold.  It already has a 70D sensor.  And it has the rapid focus capability of using focus sensors.

No. The EOS-M2 has NOT 70D sensor and NOT 70D / DPAF AF system. 

EOS-M2 has same sensor and (hybrid) on-sensor AF-system as the Rebel SL1/EOS 100D. AF-system is called Canon Hybrid CMOS AF II.

Improvement over earlier Hybrid CMOS AF system in EOS-M and Rebel T4i/650D and T5i/700D: it covers a larger area of the sensor surface [approx. 80%] http://www.imaging-resource.com/PRODS/canon-sl1/ZHYBRIDAF2-400.GIF

EOS M has same sensor and same (hybrid CMOS) AF system as Rebel T4i / EOS 650D / T5i/700D.
