Jogger: Just wondering if this video sponsored (i.e. paid for) by Canon? The description is not clear.

@Chronis, you are forgetting a small disaster that claimed thousands of lives and ruined a whole region of Japan - this has set back all companies in that region of the world by years.
And the 7DII is that body that makes you feel the need to buy irrespective of the glass - because it hit's all the right notes. It's fast, it has the buffer to back it up, it's sturdy, it has revolutionary features like the flicker sync hitherto unseen from anyone. To whom is it catching up? The Nikon D7100 which can't hold it's own against the 70D? The Sony A77II with it's 0.27 seconds viewfinder blackout and only usable 8 fps?
Go ahead and sell your Canon gear. With what lenses will you pair up the Samsung? Not much available there. Or the end of the line Sony (the A77 II is the final hooray in their fast focusing line).

@Chronis, what is your beef with the Canon 7DII body? What do you think you'll be getting over the 7DII when you buy another system? One thing is for sure, in the APS-C range you won't get any better than the 7DII by quite a margin...

Two useless/detrimental filters and a CPL. Why not something else useful like a set of ND filters?

WatsonPhoto: Objectivity is the key here. There has been a lot of press about the 7D II; both good and bad. Interesting video as I always like to look at pro work. Back to reality. I always like to look at what my Canon 7D/5D III friends are shooting and D800/D810 users are doing. (sorry dont know Sony people) I dug back into the archives for some D300 images from 2009. The 7D II images are very similar. The noise is similar to original film grain when you crank the ISO. Very nice look; but not what I am expecting in 2014. I love my Canon, Nikon and Panasonic bodies but this Canon does not cut the mustard. If Canon were to outsource the sensor they would have a home run/grand slam camera.

Most of the noise you see is almost only photon shot noise in the 7DII at higher ISO levels - so when you see less noise at higher ISO then there is more noise reduction in play...

tom1234567: images are Nothing special
Samsung NX1 will be a better camera in my opinion,
with 4kvideo plus many more enhancements
Canon needs to get there act together

No lenses, no system! Samsung has a long long long way to go before they could become viable as a competition to the 7DII - by that time we will probably have the 7D Mark IV...

garyknrd: I suggest the readers that want the 7D II to read this: http://www.the-digital-picture.com/Photography-Tips/canon-eos-dslr-autofocus-explained.aspx

It explains the AF systems very nicely and is easy to understand.
Marketing and the interviewers are driving this camera to unrealistic expectations. In Canons marketing I understand ( sales ). But for a reviewer to compare it to the 1Dx and then ask Canon? VERY misleading and untrue.

Why not take the new PDF explaining the 7DII autofocus in depth:

maljo@inreach.com: Two different card types is perfect because not matter what type you have, you're in business.

I have only CF cards, all my SD cards are fixed installed ones and still I bury 2-3 per year because of failures...

The Davinator: No 4K video. Same rehashed sensor tech from more than 5 years ago. Looks like Canon has been asleep the last half decade.

@Dave, the competition doesn't have 2 stops better DR - that's all due to measurement and interpretation errors by the only company that does such hapless measurebating...

viking79: Canon should start buying sensors from Samsung so they can get 4k video in APS-C :) Is this really all Canon brings to the table after 5 years?

You mean the very sensor that has to drop the 14 bit A/D conversion down to a 12 bit A/D conversion the moment you want to shoot a series?

The technology behind the sensor isn't much older either. 5 years ago nobody even thought of embedding PD-AF sensor cells on the main sensor, Canon was among the first to do just that and in the 70D/7DII sensor they managed to split each and every sensor cell in half to get about 30 million PD-AF sensor cells without losing a single pixel to the final image. So whoever says "5 year old technology" has clearly no clue whatsoever!

nerd2: 4K is a reality. We are expecting descent 4K IPS display at around $400 soon (check the news please people)

Call me when it appears. I bet that is about 2-3 years away. Until then there isn't even a decent display you could calibrate. And then you need to upgrade your computer and graphics card to be able to drive it, the software isn't ready for the high resolution either - not even Photoshop CC can handle high DPI displays...

Ian SS: It is too little too late, obviously Canon is protecting their higher end cameras, we will see how good it sells. For me I am seriously thinking about leaving Canon.

In what way is putting in the by far most advanced AF module in any DSLR (APS-C or otherwise), dual processor, most durable APS-C shutter and a whole host of other valuable features protecting their higher end cameras. Heck, even the 1Dx doesn't have the outstanding focusing capabilities the 7DII now will please it's owner with!

In reply to:

Karl Gnter Wnsch: If the "Sport" version is geared at the professionals which do not care that much about weight, why isn't it at least f/5.6? As f/6.3 they are missing the limit of the focusing systems - and since that is a physical limit the focusing on almost all DSLR will be compromized and not function as advertised and guaranteed by the manufacturers!

The new D750 is one (new) camera, how many more do have f/8 focusing capability?
"So it will work up to F8. Probably F11 with the center point. "
That's highly unlikely as f/8 already is very very tight and when a focusing module allows for f/8 focusing it also means that it's less precise for all apertures.

@D1N0, the -3 EV focusing has nothing to do with the aperture limit imposed by the beam splitter positioning. If the beam splitter is designed to work up to f/5.6 then at f/6.3 the focusing will be unreliable even if you try it in blazing sunshine.

@Plastek: No it doesn't depend on the amount of light. Autofocus works by separating certain light beams and these are blocked beyond f/5.6 or f/8 (depending on focusing module design, for most cameras it's f/5.6 - and for the rest of the cameras it's f/8 only for a very limited number of focusing points located in the very center of the frame) by the aperture.
So only light that has passed in close vicinity of the aperture will reach the focusing sensor and many of the photons making up that light have been affected by the inevitable diffraction and thus are no longer fit for the purpose of focusing. Our sun could go supernova and the focus would still be compromised and have reliability problems!

b534202: So the 2x TC will work with these?

@Plastek, no it won't. You will have a lens+TC combination that is f/11-f/13 wide open, that means that the combination is diffraction limited even then - focusing will not work at all, about the same chance to get that working as satan ice skating to work...

Again they both have FF coverage as having smaller frame coverage does have not a single benefit for telephoto lenses!

It will be mountable but there will be not a single DSLR that will be able to focus with that teleconverter in place...

Those lenses are lighter because they use lighter housing materials, APS-C limited telephoto lenses do need additional internal baffling and would thus be heavier if they used the same housing and lens materials. You can not make any of the lens elements on the subject side of the aperture any smalle and the lens elements on the image side of the aperture aren't that big to begin with.
