They could do both: provide optional flip up for the semi-transparent film, which could be used in low light (slower frame rate). Leave it in place in good light for higher frame rate shooting.

It sounds like an interesting idea, but then you have the dark OVF, too. This could only be done with an optional EVF... Furthermore the AF_Modul would be rated at f5.6, too. The AF is not good at f5.6 (no double cross etc.).

Believe me, there were a lot of ideas back in the last two decades of DSLRs ;)

Fast Mirrormovement @12fps and more with Liveview and Global Shutter seems to be the best solution for me.

Or use a semi transmissive fixed mirror. Then you get fps and no view finder blackout at all....but still being able to look though the lens.

Yes, Canon already had that, but it darkens the OVF quite heavy. Furtermore you loose 1-2 stops of light to the sensor which has to be compensated. This is a Cul-de-sac for the majority, I think.

That's just the thing, in order to get that 30fps rate you have to go mirrorless.

No, that's a marketing-myth from the mirrorless department. You can leave the mirror open and use the same techniques as the mirrorless does. The DPAF is even better for this than the existing solutions. You will loose the good AF-Modul, but you can do anything else as "they" do.

Taking a 4k Video ist nothing more than shooting @50/60 fps... (and a smaller images of course).

What is so special in D810 that 5ds and 5div (assuming specs are more or less correct) cannot achieve?

Noooo. Don't feed the DR-Trolls! Not another dead thread please...

However, we can not forget that the 40Mpixel sensor has 4 pixels covering the same area as each of the 10Mpixel pixels and that if you bin those 4 pixels together in post production you end up with very similar performance to the 10Mpixel sensor.

I think this this the main reason the myth persists.

You assume the area of both sensors are the same. This may be true in theory, but practically there are microlenses above the pixels/sensors. Please look at the schemes of such an structure. 4 small lenses have not the same area as one lense one the whole area of 4 small pixels. You didn't answer my question anyway. I guess, on purpose.

Having higher pixel densities just reduces ISO performance.

No it doesn't.

Yes it does.

Someday someone needs to explain to me why this myth persists after a decade of things going the other way despite similar basic sensor performance (QE).

It's no myth, it's physics. Did you ever ask yourself why the ISO-Monster A7S has lesser Pixel (12MP) and the 5DS with 53MP looses ISO against the old Model (ISO6400)?

I do not understand why some people hate STM

You never focus manually, right?

49 mm filter thread? Why? Why not keeping the common 52 mm to avoid replacing the filters?

You can easily step down from 52 to 49 with your existing filters. Adapters are available for $2 or less.

Is STM the only advantage?

For me STM is an disadvantage. It's not bad, but I don't like wired Focus and for me it's even noisier (despite what they claim).

No IS? Why not a pancake?

We don't know yeat. But 50mm 1.8 without IS would be a shame, really.

But I think all those complains about a bad bokeh, because of the smaller entry-diameter, are nonsense. A Zeiss 50mm f1.5 or Leica 50mm 1.4 are even smaller and quite good. Let's wait and see what's coming.

oh really?
and suppose something unexpected happens and you are close but have no flash and they need a shot and there is terrible back lighting?

If you carry a 1D Pro Series camera and you have no flash you should set up the ISO ;) If you miss it to a real shoot you should think about your job. Popup-flashes are really useless, they do nothing except of flashing something near to death. It's not the problem to have it in the cam, it's the problem that you carry it with the cam for 99% of the time, not using it. You make the body bigger, heavier, more prone to water and the viewfinder is more complicated for a decent 100% view. The flash even sucks on your batterylife. You can Put a 270EX on your Body every time you go out.

Nikon has a flash in the body? Wow. Leica doesn't. And the real Pro Models are D3s and D4 not the D800... guess what. They have no flash  8)

A FF with the same pixel density as the 7D2 would have 20.2*1.6*1.6 Mpixels, or 51.7Mpixels. (Actually the 7D2 sensor is a hair bigger than APSC so the crop factor is slightly smaller, perhaps 1.58?) A crop factor of 1.583 would give you a 50.6Mpixel FF camera, so my suspicion is that the pixels are the exact same size as on the 7D2.....

OK, then maybe a hint to global shutter? Readout of a global shutter is told to be slower ;)

Those small pixels give us ISO 16,000 in the 7DII.

No, the Pixels of the 7DM2 are larger. Should be anything equal to a D800 (36MP).

By the way...never wondered why ISO 16000 is no real full stop in the exposure-line? ;)   I guess the cam already pushed it internally. The 7DM2 is quite likely @ISO6400, also. But internally the newer Digic will push it 1.3 stops up...

The BEST thing on this rumour? The 5D Mark 3 will get cheaper real soon! ;)

Sometimes I don't understand the customers... wanting a High Megapixel cam but ISO409600? ;)  Haha. Of course you get ISO6400 with that small pixels... but if the sensor is a recent Sonysensor then you can easily Push it up to 2-3 stops. The H1/H2/H3 Modes will be quite clean I think.

Canon was aiming to high ISOs in the last few years, being way beyond their competitor from ISO800 and up...

Now, increased Dynamic Range will come with decreased ISO. Really surprised?  ::)

You seem to be under the assumption, that Canon really care about video in the DSLR realm. They unintentionally started the DSLR video trend, but they have done nothing to sustain it. If they so far have been unwilling to put even basic video features in a DSLR type body(zebras, peaking etc.) then 4k video seem unlikely.

Right and more importantly, they would canibalize thir own existing products (e.g. C300).
