now that they have gapless microlenses and such you don't lose much by going to smaller photosites, any individual photosite is noisier if it is smaller but all together it's reasonably close to the same, withing reason.

Not quite. You still lose FWC when moving to a smaller pixel. Since both large pixel and small pixel sensors all use gapless microlenses these days, use of microlenses on sensors with smaller pixels really doesn't level the playing field like it did when it was first introduced. Microlenses improve Q.E. by increasing the number of photons that actually make it all the way to the photodiode, but photodiode capacity is entirely dependent on area...and in that respect, all else being equal (which is pretty much the case these days), larger pixels are still better.

There are other technologies that can still improve Q.E. on sensors with smaller pixels. Lightpipe tech for FSI sensors, BSI sensors, weaker CFA's, etc. are all techniques used on higher density sensors that can still help level the playing field. Even with those technologies, FWC of higher density sensors is usually less than 40k electrons/pixel, where as FWC with lower density sensors gets as high as 100k electrons/pixel. Granted, you can always downsample a higher resolution image and reduce noise, but generally you buy a high resolution camera for a reason, and the final output is usually upscaled, not downscaled.

In the end, once 180nm technology normalizes across the board for brands and sensor sizes/densities, I think the choices will boil down to two key things: resolution at the cost of noise or IQ at the cost of resolution. Personally, I'm fine with those choices...you can always own two cameras for different purposes. ;)

As I said each individual photosite does worse but taken together....

And I also said "do reasonably close to" as well as "within reasonable differences between photosite sizes" not "exactly the same" for "any possible difference in relative photosite scale".

With the current tech, a 40MP cam, overall, not 100% view comparing each photosite, doesn't have more than a a very modest bit worse high iso performance than using same tech on a 12MP it would seem and might even do a trace better for low iso dr. You gain so much more from the extra detail/reach compared to the likely insignificant loss in high iso.

The whole point is that you don't need two different cams for two different purposes. You can just own the high MP cam and when you care more about detail then print super large, view 100%, etc. and when you do care about noise then just print or view it at the same scale that you'd have to do with the lower MP cam. You very nearly get best of both worlds.

any rumors on when? I'm planning on purchasing another DSLR here soon. I'm willing to wait for the 7d's price to drop upon announcement of the 7d mk ii, but only if it'll be February or sooner.

There will be a real (big megapixel) replacement for the 1Ds Mark III with an outstanding image quality.

All big megapixel sensors (prototypes) are in an 1D X style body.

Can you comment on difference in sensors among 1Ds3, 5D3, and 1DX?  Thanks for your knowledge.

M.S.T has never backed up one single thing they have said and they have claimed some pretty NDA covered type stuff. But when you can't even post an image from an NDA free, fully released lens you claim to own, or even an image of the lens, then I think that is a good measure of their real knowledge.

LOL!!!  I thought the same thing :-D

all of you who are interested in small/big pixels. noise etc.
read this papers by Emil  http://theory.uchicago.edu/~ejm/pix/20d/tests/noise/noise-p3.html
Thanks for the link, MR.
I'll read that and see what else I might learn from it.

I haven't examined pattern noise in detail from too many cameras other than to notice that some banding is fixed (sensor system hardware) and some is inconsistent but repetitive (electronic subsystem interference, e.g. from noisy power supplies)

but they'd better get rid of the banding and pattern noise problems for both new bodies, especially at low ISO. It's become a pathetic weakness already when competitors' cameras costing under $400, like the ultra tiny Pentax Q or D5100, can supply raw images without banding problems.

+ 1

The banding noise in many pictures from my 7D (even the region of ISO 400) is one of the most important reasons for me wanting to upgrade to the 5DIII

RE to: privatebydesign

Believe it or don´t believe it.

I am not willing to post any pictures in the net.

In the future I don´t post the hints in the forum and send the hints only to the admin.

I love my 60D.  And the 70D as listed isn't an adequate upgrade... I really don't want to pay for a 5d mkiii, but it looks like that is what my upgrade path will be.

That seems to fit with Canon's strategy.  The 60D was an upgrade path for Rebel/xxxD owners, and for 50D owners, the 60D wasn't an upgrade - the 7D was a better choice.  These specs are consistent with the same: xxxD -> 70Dor 6D, 60D -> 7DII or 5DIII.
i did exactly what you just said, i got the mkiii; NO REGRETS

RE to: privatebydesign

Believe it or don´t believe it.
I don't believe you. I do believe that you have stated the obvious, basically what these companies always do. I don't believe you have any advanced insider information.

I am not willing to post any pictures in the net.
I understand and respect that, I generally only post test shots, but a low res casual image of the 1200 f5.6 you claim to own would not have been a difficult or compromising image to post, your failure to post simple images of non compromising things you claim to own, naturally, has an affect on your credibility. ( http://www.canonrumors.com/forum/index.php?topic=11481.msg205783#msg205783 )

Fine by me, I just hope they get CR0 ratings if they choose to post them at all.
Private, Im with you on this one. Claims is one thing evidence is something else.
