1) No. You have not seen that. 2) No. It is not confirmed by anyone - because its not true.

But yes, it is a widespread internet myth about large MPIX cameras.

Actually WE have confirmed that high megapixel cameras ARE problematic when it comes to shake. The issue has more to do with photosite size since a higher megapixel count is being put into the same small Full Frame sensor (i.e. Canon 5Dsr). You simply need to use a higher shutter speed to counteract the less light input to saturate each pixel, motion blur due to sensor readout time increase and the higher inherent noise of Canon's high megapixel count sensors.

The direct comparison of a Fuji GFX-100 vs Canon 5Dsr is striking because of the larger sensor size and the larger individual photosites. The GFX-100 is an OUTSTANDING CAMERA that makes much better images than ANY current Canon camera! ....BUT.... I still like the 5Dsr more than the Fuji because of it's more comfortable grip and intuitive ergonomic feel in my hand. I would LOOOOVE to have a larger Canon 1Dx body with a Fuji GFX-100 sensor in it.

And right now, only one company will be coming out with such a beast and it ain't Canon OR Sony OR Fuji!

I welcome your proof of this claim. Otherwise I have to read "WE" as "I" and disregard the comment as it runs counter to the optical laws that normally determine the amount of camera shake in a resulting picture.

I should clarify WE as a corporate entity that has a LOT of cameras! (i.e. more than 300 still and video cameras!)

The issues specifically we have for the 5Dsr series is endemic to this type of high megapixel FF camera due to the small photosite size and typical shutterspeed issues at high ISO at or above ISO 3200 ... it's a colour fringing on object edges especially on Red and Blue items. It really has more to do with the DSP on the DIGIC processors and low readout speed than physical camera shake.

The 5Dsr simply does not have enough CPU horsepower to do advanced colour rendering and smoothing like the 1Dx3 can do!
You WILL get very slightly soft edges on things like blue or red shirts or fine checkerboard patterns. I just do an UnSharp Mask to mitigate the problem after I do my colour correcting during post production.

I really do think the OP is using TOO LOW of a shutter speed (i.e. less than 1/200th) on high action subjects which will give you DIRECTIONAL MOTION BLUR rather than overall image "softness". Just up your shutter speed to 1/500th and ISO 1600 to get what you need without too much noise. Brighten your overall image in post production by 5-10% to your taste and then boost your shadows by 10 to 20% to recover dark areas of the photo. Any slight softness can be mitigated by an UnSharp Mask.
