Canon filled a patent for a foveon type sensor. If there will be a 46.1 megapixel camera I expect the foveon type sensor in it.


I like the idea behind foveon type sensors - think it is right way to go regarding sensor tech... From Sigma's application of it, high ISO performance seem to suffer though. If Canon can come up with a good high ISO and DR performance on a foveon type sensor, I am getting one...

Cheers!

Update: This would equal photosites equal to those of app 15.3MP on an FF. Not sure to what extent it helps with high ISO though. If I am not mistaken, issue with the high ISO performance on foveon sensors is the red channel.  Being measured last, it is suffering in low light...

The current Foveon also has 46MP, so that would mean a 15.3MP APS-C sensor... for what sort of price? :O

16 bit - weeeeeee!

Much better gradients and tonality. Lovely stuff.

Can anyone explain to me what 16 bit means?  Other than that, the specs look good

16 thousand tonal values vs 65 thousand tonal values

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?

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 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.
