It sure would be great to have one of each!  8)

I'm sure Canon will grant your wish and never produce a "one does it all" camera even if they cold - what's better than a customer buying one camera? Buying two :-)!

yea on that note... I wonder if Canon is deliberately segmenting the market, or just playing the R&D that they have in hand.     For example,  The 5D3 appears to optimize high ISO for wedding/event because thats what they thought people wanted.  Then D800 came and showed that higher DR can be had at low ISO and folks started complaining that 5D3 couldn't do that too --  I suspect 5D3 is Canon's high-ISO optimization of their current capabillities.   

So the next crop of Canon sensors will reveal their real capabilites, and telegragh the compromizes they must (or choose to) make, i.e the extent to which the 46.1MP beast has to compromize high ISO noise performance in order to produce better DR/shadow detail, or if new technology will make real and significant contributions in both areas.

Let me guess - yet another recycling of the T2i/60D/7D/T3i/T4i/ pixels, just in a larger sensor.

18*(1.6*1.6) = 46.1
Either that or it's a new crop sensor that will eventually go in the rebels and 70D but starting with FF version first. An even greater level of the technology dropping from top to bottom.

well it is a CR-1 rumor so the actual pixel count could have been derived using this arithmetic just to start the rumor and just to watch people get their calculators out and entertain themselves

So what do you think Canon would call this if it comes out?  1DXs  or 1DSX?  lol

Should I sell my 1dx??

Very confused: 18mpx for $7000.00
46mpx for HOW MUCH?

Paul

You aren't paying seven grand for the megapixels, man! Your paying for the tank-like build, the everlasting shutter, the ungodly-fast 12fps shutter rate, the best AF and metering system in the world, beautiful high-ISO performance with low noise, etc.  Megapixels are cheap (as evidenced by the 36.3mp D800), and not the primary cost of a high-end camera anymore. Its the other features that really cost you.

If one of the OP's is correct and this 46MP sensor is a Foveon sensor, this is similar from what I understand is in Sigma DP MERRILL point and shoot that has a few good reviews.  However if it was this simple and that great, wouldn't this already be a trend by now?

Last year I met a photographer who actually had done extensive research on this Foveon sensor and his advise to me then was to 'give them some time to perfect it'.  He was shooting a Canon  5D2 and had numerous Sigma and Canon lenses but advised me to stay clear of that technology for now.

Your thoughts?
A few cameras (Canon, Fuji & Sony) and lenses and a lot of creative energy and imagination.

caution is good, me thinks.  my thought is that one shouldn't pre-order this puppy without seeing some test results.  who knows it might be stunning or it might be lackluster

The Foveon produces the most amazing IQ ever, as long as you don't go past ISO 400.

Correct! If I m not mistaken, the foveon research at Sigma was quite inflamed and there were many issues and delays. Not sure if Foveon had equal amount of R&D thrown at it as bayer filter sensors. Though I do think foveon is based on a more efficient idea... My hope (or perhaps rather wish) is that Canon has taken the time to, even if not perfect, improve the technology... To be seen though...

Cheers!

definately not somethign to pre-order without seeing test results :D  I'm just wondering how much ISO performance has to give in order to get the DR.  its gonna be a good show to watch, but from preliminary indications this won't be seen at very many weddings  ::).  In order to make an industry contribution is appears Canon has to make a fairly sharp distinction between the studio/'scape body and the wedding/event body.

If these specs are correct... this camera will be ideal for landscape and studio photogs....  not weddings or sports/wildlife.

Oh I think it would be quite excellent for wildlife because when you crop the picture, you'll have the same ability to crop as with the 7D. It would be the full frame version of the 7D, except perhaps in fps. Birders would love it.

I also see it as being used by quite a number of wedding photographers (that aren't amateurs pretending.)

As a wildlife photographer I shoot primarily from ISO 800 through ISO 6400.  It would be a great camera if it could hold up with high ISO, but I doubt it will. This camera will likely be a beast at ISO 100-400 and have an expanded DR which is perfect for landscapes and studio.

Until the 1DX came a long the best wildlife camera out there has been the D3S with 10mp. 

While I agree it would be nice to be able to crop and still have a ton of pixels (like a crop sensor 7D), the part that will likely disappoint here is that it will have the same IQ as a 7D... which quite frankly is not that good. 

I doubt it will be a great wedding camera for the same reasons I doubt it would be a good wildlife camera.... High ISO performance, or lack there-of. 

Just my .02

This sounds good in theory, but it doesn't work in real life. The more you have to crop, the harder it is to nail the focus. So, while it sounds good to say you could simply take a full-frame camera of equal pixel density to a 7D and crop the image after the shoot, the most likely result will be images with missed focus points. If you need a 1.6 magnification, it is best to use a camera that provides a 1.6 magnification.

As for wedding photographers, I can't understand why they would pick this over the 5DIII, which was designed with their needs specifically in mind.

A FF body with AF that sloppy would never work well with fast primes. When cropping FF shots if I've encountered a problem it has always been pixel density, not AF.

Because 46 MP will bury 22 MP on large prints of group shots.

I don't. Noise performance is a function of technology, total sensor surface area, and then, to a much smaller degree than the first two, pixel size. It may be slightly worse than the 5D3 or 1Dx, but will be next to them, not next to the APS-C bodies.

This camera will likely be a beast at ISO 100-400 and have an expanded DR which is perfect for landscapes and studio.

DR on the other hand is directly related to pixel size, so a 46 MP sensor will do worse all other things being equal. 16-bit is a marketing gimmick if they can't actually get that much data out of each pixel. If they've worked around Sony's patent, then expect great DR despite the pixel density. If not, then expect slightly worse DR then their current FF sensors.

The 7D has excellent image quality, pretty much equivalent to the 5D2 through ISO 800. If you've ever stitched 3 frames from a 7D, you want a 46 MP FF sensor even with Canon's current technology (as opposed to Sony's).
