More bit depth does not in itself produce a wider dynamic range. Cutting the pie into more pieces does not make the pie bigger.
We shall see. If it's a Canon sensor, I would believe you but it's Sony.

No we won’t. This sensor may have wider dynamic range than some other sensor, but it won’t be because of the precision. Similarly a beaker doesn’t have greater capacity simply because it has additional grading divisions.We shall see. If it's a Canon sensor, I would believe you but it's Sony.
And....... a doubling of body and lens prices = a fairly small market.
Over 75 MP shall mean that Canon finally goes BSI (I can't see how they can make it otherwise). Will be interesting to see what sensors they use - their own or someone else's like Sony, Towerjazz or whatever. I just hope they will lift the DR to at least 14.x EVs instead of 12.x like on the 5DsR, although >75 MP on a 35mm might not quite allow such a lift.I really hope it’s not resolution for the sake of it. When the 5DSR was released I hired it alongside the D810 and always picked up the D810. You got a few less megapixels but the files were much cleaner. Better low light performance, better dynamic range and less noise.
The 5DIV was a step in the right direction and the sensor was much better than the 5DSR. Let’s hope the sensor holds up in areas other than just resolution.

YOU HAVE HIT THE NAIL RIGHT ON IT'S GLARING HEAD !!!!!
It's almost all about PHOTOSITE SIZE IN MICRONS!!!
The Canon 1DxMk2 is about 6.3 or 6.4 microns so it's image quality in terms of noise and low light capability is going to be pretty darn good! The Sony A7s2 has about an 11 to 12 micron photosite size, so IT'S low light ability is and DOES BLOW AWAY the 1DxMk2's! Now what SHOULD BE DONE in the camera industry, is that that manufacturers need to start getting into Medium Format sensor sizes STARTING at 56mm by 42mm at a MINIMUM of 30 megapixels (13.9 microns per photosite) up to 50 megapixels (6.8 microns per photosite) so you KEEP the high end low-light gathering power of the Canon 1DxMk1 and Sony A7s2 BUT get the increased resolution we so very much want these days. Lenses would be easier AND CHEAPER to manufacture AND we would get that beautiful Bokeh inherent to large image sensors!
IDEALLY, we should be moving into aspect ratio agnostic 70mm by 55mm sensors at 8192 by 6144 pixel image size (50.3 megapixels) which would give us an 8.5 micron photosite size which is probably what 99.9997 percent of us will find perfect-enough for BOTH day and night photography! That 70mm x 55mm and 4:3 aspect ratio can be cropped on just the vertical axis to ANY other aspect ratio we need for stills (3:2 and 4:3) and video (16:9 broadcast video or Cinema DCI 1.89:1). With that 50 megapixel we can EASILY use it for almost any stills and video purpose we want with enough LOW-NOISE and HIGH-END LIGHT GATHERING POWER that our imagery will be good for DECADES to come!
Soooooo, Canon, Sony, Nikon, Fuji, Panasonic, Leica, Hasselblad, Phase One, etc how about getting 70mm by 55mm sensors at 8092 x 6144 pixels (4:3) onto YOUR cameras !!!!!
BRING IT ON BAAAAAABBEEEEEEEE !!!!!

After close to 1000 pictures with the R in the most adverse lighting conditions
there is only one pain point: It is too small for me. Grip and controls of the
5D MkIV are grievously missed.
^ the images on the right don’t look “soft,” they look out of focus.
All the pictures I post on this site are enlarged, so if I'm trying to make a point about sharpness, noise, whatever, that point is obscured by seeing the picture enlarged. Perhaps my mistake is resizing pictures to be a reasonable size. Maybe I should just post giant versions and the board wouldn't do that, but I haven't experimented to see. I have asked for guidelines and suggestions on optimum sizes for posting, but have never received a response.They're focused. They're just high ISO images pitting 12mp vs. 20mp and 50mp. Higher ISOs introduce softness, and when you scale down the higher rez files to the same view size it's game over.
I should also note that the image I uploaded appears larger than it does on the dpreview site. I think that's an artifact of me taking the screenshot on a 4k monitor and then the web site displaying it as if it's going to be on a HD monitor. Never the less, even at the "correct" sizing, the A7s2 is simply not as good at 12,800 as the 1Dx2 or the 5Ds/sr.
Nope. Pic related. At the same view size the A7s2 is soft and lacks detail, yet it doesn't really have less noise. Its noise is simply soft like the rest of the image. The color noise in these images disappears with default color NR (dpreview naturally turns this off) leaving the A7s2 at a severe disadvantage to the 1Dx2 and the 5Dsr at ISO 12800.
Typical reviews and online memes suggest the A7s2 is one of the best high ISO cameras. The same reviews and memes say the 5Dsr is "not a high ISO camera." I would rather work with a 5Dsr ISO 12,800 RAW file any day of the week.
As for extreme ISOs, the 1Dx2 and A7s2 show the same behavior through 409,600. The noise level is about the same but the noise is literally sharper on the 1Dx2, like the rest of the image. People tend to have an aversion to sharper noise while pixel peeping but at common view sizes the sharpness and detail stands out more than the noise. And the sharper, higher resolution image has more room for NR if the noise really bothers you. No matter how you slice it, the 1Dx2 is the better high ISO camera for stills. (Video can be another beast entirely depending on how the image is captured and scaled off the sensor.)
Since the introduction of gapless microlenses pixel size has not mattered for high ISO, given the same sensor size and level of technology.
DR should, in theory, be affected by pixel size. But in practice we're not seeing that. Some of the highest pixel density 35mm sensors are also the highest DR sensors, higher than MF offerings. And this has occurred not only with Sony's on-chip ADC sensors (Nikon D8x0 line, and now A7r3), but in the Canon line with off-chip ADC sensors. At introduction the 5Dsr was the highest DR Canon body until Canon's first on-chip ADC sensor bodies.

If you like this camera, and your only complaint is that it is small, why not consider an L-Plate?
Amen to that!That would be mandatory, anyway. But it wouldn't generate
extra free manoeuvering space for my thumb on the back,
and it won't give me back the natural placement of index finger
and thumb on the control wheels.
The next R hopefully goes back to the proven ergonomics of the 5D MkIV.
Photokina 2019 chancelled.
Imaging industry and Koelnmesse decide on new starting point for the new annual cycle
Following a successful photokina 2018, the German Photo Industry Association (PIV), as conceptual sponsor of the trade fair, and the event's organiser Koelnmesse have agreed not to organise the next leading global trade fair in May 2019, as initially planned, but in May 2020. From Wednesday 27 May 2020 to Saturday 30 May 2020, all the market leaders in the imaging industry are expected once again in Cologne. The decision to postpone the start of the announced annual cycle by one year is intended to give all participants the opportunity to further develop the new concept for photokina and to tap into new target groups among exhibitors and visitors in order to heighten the status of the trade fair as a global platform for the photography and imaging industry.
Of course Canon can pack a ton of pixels on a small area already, but that makes it practically useless except some very special scenarios in which we hardly ever shoot. Just look at their own video, and notice the heavily blown-out highlights on the right capture that are not blown out on the left one. The dynamic range they got out of the sensor downright sucks, although on the very shot it looks contrasty and appealing. Real world shooting is an entirely different story, though!They can easily make a >75MP full frame sensor which isn’t BSI.
This APS-H sensor is not BSI, is smaller than full frame, and has 60% more than 75MP.
