EOS-1D X Mark II Sensor Talk [CR2]

[PureClassA]

Very True. I just meant that I don't think the statement necessarily precludes higher FPS, but they obviously needed more processing power to do it. The shutter mechanism is another story, as is how fast the AF can grab focus again between each shot. But yes, assuming teh same shutter, we get the same FPS. New shutter, maybe more. Also assuming we get a Digic 5 or 6 dedicated to AF like the Digic 4 is now

I don't think the rumor's mention of "using Digic 7 to keep up with frame rate on new sensor" necessarily precludes it from meaning "no higher frame rates than 1DX" Grain of salt folks.

I think the 12 fps of the 1D X is limited by the mirror. It can do 14 fps, but only with the mirror locked up.

So 12 is the max limit because of the mirror? Actually I can live with that.... Maybe one day mirror less will surpass that along with other limitations...

Sort of. There are some caveats to reach 12 fps, like a fast enough shutter speed, aperture not more than 4 stops down from wide open, ISO under 25600.

CROP MODE PLEASE!!!!!!!!

Why?

Because it is nice to have a lot of features. (Just kidding)

IMO it would be great for very fast/erratic action of moving subjects. It is helpful to know how to correct the camera viewpoint using the information what is is outside the frame. Or think about some sports where you wait for a runner passing a hurdle: You can see the runner and "preload" your timing parameters ...

I have used a combined 35mm / 70mm external optical viewfinder (Galileo principle or similar) and it was fun to frame for 70mm with a 35mm equiv. view.

Well the shutter and mirror assembly itself is the only hard mechanical limitation. Regardless of shutter speed you select, there are only so many actuation per second the motor can perform to lift and reset the mirror. Same with opening and closing the curtains. Then there's how much data can be managed through reading, buffering, and writing. Like Neuro said, shutter speed, ISO, and Ap can be manipulated by the user to reach whatever the hard ceiling of the mechanics and data processing streams are.

Yes but even a crop mode has the same hard ceiling as FF given the same mirror/shutter assembly. Cameras that have higher FPS in crop than FF exist, but the FF FPS is limited by data processing capability, not mechanical mirror/shutter. On those cameras, if they can produce, say, 8 FPS in crop but only 5 in FF, it's not the shutter bottling up FF FPS, it's the processor (or a deliberate firmware limit put in by the manufacturer). That mirror/shutter can sling 8 FPS. period.

Trying again as non-native speaker: If you can SEE some object or parts of it OUTSIDE the CROP frame but inside the viewfinder you have a better chance to control the camera view point to catch the object inside the frame at the RIGHT TIME as you want it. Shure, just crop in FF is limited by the max speed of the larger FF mirror assembly.
I am shure you need sth. like 20-50 fps to catch a decisive moment in fast action by accident. A well trained shooter might catch the decisive moment after extensive practice.
Or as comparison: A drummer might be precise to roughly 1-5msec but he needs some 10-100 msec to prepare for a break.

I asked for improved DR and noise performance, 24-28MP, 1-2 stop improvement in high ISO and improved support for manual focus. It seems this is getting fairly close, so I´m looking forward to it.

Nope, I still don't get it. What if you misframe that fast moving action slightly? Sorry, your camera threw away the rest of the image. That's why there's:

Eldar: If I am correctly informed by some of the tech experts on this forum, your hopes are reasonably high, but according to them (e.g. jrista) you may hardly expect more than 1/2 to 1 stop in high ISO improvement. For my interests I would like to see the same improvement in a 5DIV, or as I hope in another 5D body with an even lower MP count.

 

[bdunbar79]

Well, if you put in a larger sensor...

Well, if you put in a larger sensor...

And a larger viewfinder with 'FF' crop marks...

Has the method of achieving the 15 stops of DR on the C300II been definitively determined? I was making an educated guess on the implementation of the dual column ADC patent Canon had in 2013, but someone else in here mentioned ISO manipulation. Whatever the Cinema used will undoubtedly be the same as the 1DX2. Thoughts anyone?

 

[3kramd5]

Yes. By canon

A couple of little hopes for the 1dx II

• Ability to WIFI voice memos with image
• Ability to write voice memos to both cards at the same time
• Ability to lock settings on camera, ie all settings easily.
• Ability to chatter to Profoto air devices through camera menus
• Add Canon EX Speedlite power to exif in ETTL mode
• A truly silent, silent mode, a la 5d MK III
• Better meta data - ie perhaps be able to better integrate in the camera a la Photo Mechanic - perhaps bluetooth IPTC stationery from Photo Mechanic to camera, so wifi images have meta data.
• A couple of user assigned versions of focus tracking options rather than editing existing.

 

[LetTheRightLensIn]

All good news...

how so?

Oh I know. Because every single part inside in it will have the Made by Canon stamp on it, which is the only thing that matters to Neuro. The part could be awesome, terrible, decent, who cares, so long as it's MADE BY CANON.

More MP with no frame rate reduction, similar ergonomics. It ain't broke, they shouldn't fix it (contrasting with a prior rumor that mentioned significant ergonomic changes).

And maybe some are willing to leave with the chance of that on the bodies where RAW crop could allow for more fps and much better buffer performance (and, of course, less storage space). That can be particularly handy when shooting distant, non-currently flying birds and animals that you are never getting close enough to go past frame boundary. Or say surfers on a wave breaking at a particular distance that works out.

Such a mode would have made a ton of sense on a 5Ds, but marketing had to make sure people need a 7D2 too or snap up the 5Ds2.

Now granted, with the 1DX2, the buffer performance will probably already be pretty decent in FF mode and the fps will probably be mirror limited and the space isn't quite as big a deal 25MP vs 36-50MP. It could still take the buffer to essentially infinite (might not matter so much for the bird shot scenario above since the buffer is probably already fine for that, but it could possibly still help for surfing) and save some storage space though. But yeah on a 1DX2 the RAW crop wouldn't be nearly the huge deal it could be on a 5Ds or 5D4 (and is on a D810/D800).

Yeah no way it goes 2 stops better high ISO and even 1 stop would be really pushing it.
Cameras are simply already too good at high ISO mid-tone SNR. If some sort of sensor that captured color info perfectly with no filter array loss and itself was improved beyond that about as much as could be came out then you might get your 2 stops. But I don't see anyone releasing such a beast any time soon.
