New Canon 5DS/5DSR specs leaked

With the same sized overall sensor gathering the same amount of light, reproduced at the same size, that would be no. Per pixel yes, but overall, no.

So...with doubling the count in the same FF area, each pixel must be smaller.

the pixels get smaller but the more megapixels the better, right?

Right.

Sampling the same data at a higher frequency always yields results that are either better or equal, but never worse.

when resized to the same image size, it can potentially be LESS noisy!

but we really cant say how canon will bring out the sensor. For marketing purposes, they can dumb down the sensor to make it really poor at high ISO's. With the 7D2 having 16000 as native iso, there is NO REASON why the 50mp version cant have the same native iso, unless canon purposely dumbs down the camera. If they kept the same 7D2 sensor and doubled the surface area, I think it would beat the 6D's high ISO.

But supposedly the old 5D classic years ago had fantastic images with LARGE pixels !

Is it the frequency vibration?

Maybe we need a quantum physicist to explain better pictures

Apparently not:

Looks unknown to me. The link has:

The high pixel density sensor will produce more internal noise, meaning poor High ISO performance in “full resolution mode”. Of course, better A/D conversion in-camera software and more powerful processor will help to fight this issue. We can only tell how good it will be when the Canon 5Ds is released to the public.

Above this the site speculates Canon may combine pixels, but this is unknown and would depend on software and yield a lower resolution file. Seems like a lot of work, which it may not even do, to end up with a 5D3 equivalent image. And are we not at 20+ mp past the resolving power of current lenses?

That said, Canon isn't stupid. I'm sure the camera will bring benefits, but whether it is better in all areas we will have to see. Hopefully it will push 5D3 prices down

I am more concerned about the limitations of the current lenses. Of course, Canon can release a new line that takes advantage of the new camera, which will obviously increase overall costs –not that that would hurt Canon.

Diffraction is also a concern. For those of us who regularly use apertures above f/16 it'd be a deal breaker. I'm not keen on focus stacking every shot and increasing my postproduction times.

This rumored camera is hardly a 'medium format killer', it seems more geared towards callow photographers easily impressed by pixel density.

People have been saying that for a decade, and it has yet to be the case. Canon has typically decreased pixel pitch (the distance between pixel centers) by decreasing the size of the non-sensitive transistor components between the pixels. This has given them increasing pixels without actually (or substantially) decreasing the size of the photo-sensitive areas of the pixels.

apparently there are plenty of "callow" photographers who crave megapickes

Medium format killer? In some settings, maybe. With a lens that is sharp enough to take advantage of the extra pixels and with enough light, such as a studio fashion shoot, it could be fantastic. A medium format camera with the same sensor technology in the larger size would be better but at least four times the cost.

That's what made me take a gander at the 5Ds in the first place: it did appear to be a cheaper alternative to medium format, especially in my area of specialisation where I am running out of DOF constantly; but the points Mr Koloskov –who is a seasoned product photography veteran who has shot with both 35mm and medium format– makes are sound and sobering. It might still be a great camera, but we'll have to wait till we see a real unit perform in real tests before saying Rox or Sux. I'm not impressed by raw pixel density or 10^7 ISO values –I'm shooting at ISO 100 or 200 and >=f/11 most of the time anyway.

The significance of medium format is the way the camera draws the image. Each major format change has a distinctive look created by the format, focal length.

For a long time, medium format also had the advantage of extreme cropability. This was almost inexplicably mystical, even in film days. It was no big deal to crop a 24x36mm segment out of a 6cmx6cm Mamiya frame and still somehow get an image with smoother microcontrast and superior sharpness than the same square millimeters of a Canon or Nikon shot.

Although the different look of the drawing of the image will always remain with the larger format, that croppability/enlargeab​ility aspect has been dwindling as small format megapixels have increased. More megapixels means greater enlargement without interpolation, and to the extent that you haven't started interpolating the image, enlargement means very little.
