It's the same 11-bit DR sensor, nothing to see here, move along.

I bet you are right.

But those images honestly do NOT show any limitation imposed by a sensor with 11 stops DR at base ISO.

No new sensor == no sale for me.

Same here

What Canon is doing, is basically handing all of the first time buyers to Nikon.

Not Nikon. More likely Sony

Note that Canon would need to develop cheap kit zoom - 28-55 and cheap tele zoom 55-300 for these cameras.

Canon already has the newly introduced 24-105 f/3.5-5.6 IS STM as well as the aged 70-300 f/4-5.6 IS (non-L) cheap lenses.

I'll appreciate having 6D M2 with 60D (not 70D/7D please) AF sensor.

Why can't Canon introduce their ancient 1D2 45pt AF sensor in their later camera bodies, now that the 5D3/1Dx/7D2 already have the best?

If Canon is not happy with the sales figures of the G1X/G1X Mk 2/6D, they ought to read the reviews in DPReview.

As Thom Hogan says:

Where is the 50 f/1.4 replacement?

I'd love to see the RAW files to get an idea of what the noise is like to start with and then what I could get as a final result in Lightroom.

Need to wait for Adobe support. Currently, even with RAW files, one can only process them with DPP.

I recently downloaded a 70D ISO 6400 RAW file from Imaging Resource and processed the file with DPP and Lightroom. Even with ALL the NR sliders at zero, the DPP output is still cleaner than that from Lightroom.

However, I also compared the 7D2 vs 70D RAW files at ISO 6400 after going through DPP (with NR = 0) and they appeared very similar. 7D2 has just slightly less amount of chromatic noise.

Canon, while a highly innovative company, doesn't seem to be all that innovative when it comes to sensors. (Which is REALLY weird to me...given that they are an imaging company...pretty much everything they do revolves around digital image sensor technology.) Canon just doesn't seem to be in the sensor innovation game right now...

And this is with Aptina's current HDR technology...I can only imagine what they can do with multi-bucket technology.

Canon did change the sensor game when they first started with CMOS technology instead of the widely accepted CCD stuff. But after Sony embarked on their own CMOS sensors (first shown in D300/D3), Canon basically stagnated. Sigh... I am still waiting for them to leapfrog Sony... not sure if the day will ever come...

It translates more as "Big zoom" as in more range.

Not just that. From Canon Hong Kong:

"Canon is developing a new premium digital compact camera that combines the merits of both large image sensor and high-magnification optical zoom lens in response to the demands from users looking for high quality high zoom performance. Offering both convenience from a compact body and excellent super telephoto performance, this camera is perfect for everyday or travel shooting in high quality."

It will be competing against Sony RX10 and Panasonic FZ1000. Both have 1" sensor, and are highly acclaimed. Canon has some big shoes to fill.

As a old Sigma cams user, i can tell you that if this rumor is real you can only expect...

Newest Foveon sensor it's a terrible mistake, there is almost half a year after Quattro introduction and Sigma can't get noise level right even at base ISO100, just look at pictures there is so distinctive noise in blues and light parts of the images that even older sensors not only Merrill but even 1.7 crop Foveon sensors can get better results.

This is all very amusing to me. When Sigma Foveon cameras first hit the market, users were literally RAVING about them. They were putting down Bayer sensors in the market, especially the CMOS sensors from Canon. Of course, all problems associated with Foven sensors were either disputed, denied or dismissed.

Now, the skeletons are coming out of the closet. I am wondering if this may also be true for current users of other competing brands... you know who you are. ;D

Anyway, like what I said earlier, if this mutlilayer sensor technology indeed comes to pass, we can be sure most of the apparent drawbacks will have been ironed out already. Didn't folks make the same dire prognostications when Canon first announced their implementation of CMOS instead of CCD sensors? Sigma may not be able to resolve the accompanying issues of multilayer sensors, but this does not imply Canon and Sony (which also has patents on multilayer sensors) do not have other clever tricks up their sleeves.

Maybe they have some totally new tech that makes it able to do better at high ISO and low ISO than the regular type of sensors they are using now? And maybe it provides great colors and they have a ton of processing power to handle all the data and the less efficient data storage is more than outweighed by how well they have the basic tech working (CFA filters rob a lot of light, if they managed to capture almost all of it with three layer that could be the only way to give a big boost to high iso at this point; but it would take some amazing new tech as all the current three layer tech actually does worse in most regards)?

If not, though, then it does seem potentially questionable yeah.

One thing we ought to remember is that when Canon first embarked on CMOS sensor technology, there were lots of skeptics out there. At that time, most believed in the superiority of CCD to CMOS, until they were proven wrong. ;D

On another note, Sony also has a patent on multilayer sensor:

So, Canon is not alone. Almost appears as if Foveon type sensor is the Nirvana for sensor designers, despite Eric Fossum's doubts. ;D

So what's the point, then? It sounds like there are lots of drawbacks with the only potential advantage being "truer colors."

Does modest low ISO DR mean worse than current Canon sensors, similar to current Canon sensors, or similar to Canon sensors with the potential for a big DR increase given innovative tech/manufacturing?

There is another plus: DXOMark won't be able to grade the new sensor, just like they do not test Fujifilm sensors with their unique RGB layout. So, less DXOMark angst in these forums. ;D

As for DR, high ISO performance and AF speed, no one really knows how these will be affected. But if Canon is confident enough to introduce new sensor technology into their top end body, I am sure all these potential drawbacks have already been addressed. Let's hope we do not see a repeat of the 1D3 AF saga.
