I used your own formula, i.e. when we double the number of pixels, the resolution gets multiplied by the square root of 2. So the factor is sqrt(2)/2.
If you used my formula, you misapplied it. I wrote that "The 21 mpx sensor has 6.4 µ pixels, the 50.6 has 4.14 and so the expected increase in spatial resolution is 6.4/4.14 = 1.54."
My formula, which is simply that spatial resolution scales as the sqrt of the pixels per same size sensor, gives the same result within rounding errors: the expected increase is sqrt(50.6/21) = 1.55.

The best "bridge" camera by a country mile, or maybe 10, is the Sony RX10IV. Its 24-600mm equivalent lens is simply incredible - it resolves at 600mm as well as does my 100-400mm II on my 5DIV and is really, really sharp at 24mm. And, it has the A9's AF system and can AF and AE at 24 fps in continuous AF mode. It is also about the same size as a 5D and is nice to hold.
Just looked at the specs... WOW!

Yeah I probably misread it. Yes given pixel sizes p1 and p2, and corresponding megapixel counts M1 and M2, pixel size ratio p1/p2 = sqrt(M2/M1)

I just love the extra reach and detail the 5DSR gives me with my lenses. I have just downloaded and processed this pair taken with the 100-400mm II on the 5DSR of a yellow-billed kite on our safari. The 5DSR focusses very quickly in AI Servo as you track. The bare 400mm lens on the 5DIV gives similar reach to a 560mm on the 5DIV but the wider field of view makes BIF easier to track frame.

I AM VERY VERY IMPRESSED by these Raptor photos....This is TRULY what photography is all about!

KUDOS and GOOD JOB on these SPECTACULAR photos!

I'm sure this camera will be nice for some people but Sony 16 bit sensor is calling for me. No more bracketing would be a game changer for me

#### derekbez

So, how would they name it?

EOS RDs? RDs R? Rs? RsR? RR?
This would be the RD2. The next iteration would be the R2D2.

You went there. Thanks! Good chuckle with coffee!

RTARD would suit the"wishers" who need soooooo much more than whats on offer and will 'tell' Canon that they "need" moreof what 'Nikon' are doing - so right" because their cat pictures have crappy dynamic range

Please be nice and not call people names, or we will be forced to send the kitty of Christmas Cheer to visit you.

More bit depth does not in itself produce a wider dynamic range. Cutting the pie into more pieces does not make the pie bigger.

I'm just a happy camper, counting my blessings. If more comes, great, otherwise life is good. I'm a fanboy of all the brands!

You do follow CR because of its humour!

Speaking of which, my pie analogy reminds me of the guy who told the waiter that he wanted his pizza cut into six pieces rather than eight, since he needed to cut down on his eating.

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 !!!!!

I'm waiting to see what Canon does, but the forthcoming Sigma Foveon in L mount intrigues me more.

I really would have liked to see a 1DsIV from Canon.

And right now, Pentax is the only manufacturer (brand) with a wide range of existing lenses that would work. They even have the camera body. Just need a sensor...

As far as "cheaper to manufacture" lenses, look at the current DA Pentax lenses- which are NOT cheap, nor are they made in Japan even.

Apart from that 75mp number, the rest would be disappointing.

And....... a doubling of body and lens prices = a fairly small market.

And portability! You think a 1DX2 is heavy, try hauling around a 4X5
