Canon have an inflated price structure ...

+1000.

Canon released very good products this year, actually.
But most (all?) of them are overpriced.

Ditto if the new 7D as an APS-C camera had IQ = to the 1Dmk4 it would be pretty awesome.
However I would not hold my breath for this being the case

1DIV-level of performance shouldn't be all that difficult to achieve with a 1.6x sensor made on a newer tech.
Provided that MPs are kept in check, of course.

The question is, what will Canon do with the 7D successor.
Will they go for a more pro-oriented body or a more general-purpose body?

If the former, I could see the 7DII using an improved 16-18mp sensor, which I'm sure will match the 1DIV in image quality.

But Canon might as well decide to crank up the megapixels.
In that case, it's hard to tell if the 7D successor will be even called 7DII  :-*.

Question: If Canon does implement this tech in a 7D.2, could that APS-C camera produce lower noise at low ISO than current FF cameras?

Even if the 7DII sensor is made on the rumored new tech, the best we can hope for is performance similar to the 1DIV and 5DII. 
Just consider that for 1 stop better ISO performance, the sensor needs to be 2x better, basically.

It's not the same sensor.  Canon's web site describes it as a new design.

Of course it's not the same - it's 20 MP, not 22 MP.  But if it uses the same production technologies found in the 5DIII and 5DII, the IQ should only be marginally different, if at all.

There are rumors flying around that parts of the 6D sensor are made using a new production technology.
So, some improvement seems likely. We'll see how much.

Here's the 6D studio shot at ISO-6400. And here's the 5DIII shot.

What are you talking about?

I just compared the 6D at ISO-6400 vs the 5DIII at ISO-6400 ... and the 6D is cleaner and with better colors.

Overall, the 6D image quality is shaping up as better than the 5DIII.

Canon seems to do well regardless of whether their technology is the best or not.

Aah. You must have missed the discussion about the last quarterly results from Canon and Nikon.

DSLR sales at Canon were down for the quarter (compared to 2011), while Nikon's sales were up.
Canon blamed it on the strong yen and delayed introductions.
(How is the strong yen affecting Canon but not Nikon ??? )

The fact that Canon is down for a quarter is certainly not a big deal.
But if you are down while the competition is up, then you have reasons to be concerned.


Overall, Canon was not doing all that well last quarter.
They've been overpricing left and right in the last year - but if the last quarter is any indication, their overpricing strategy is not working out.

You plain and simply stated, as quoted above, that Canon does not have "BSI technology". Having technology does not mean it has to be fabricated in a sensor.

What if Canon's R&D team just simulated this BSI technology on their CAD/CAM workstations?
And then filed a patent based on this research.
Would you say that Canon has a BSI technology?

Lets stop mincing words.

A good, common sense definition of 'having a technology' is that you have products based on this technology.
Alternatively, 'having a technology' might just mean that you have filed a single patent based on paper research.

It can be argued that both of these are valid definitions.

So, when I said that Canon does not have a BSI technology, I was actually quite correct - as per the common sense definition above.

Without understanding too much of tech here, if that is the case with the 6D, a next 5D could be fully equipped with 180nm sensors. Which would yield more than an incremental upgrade, right?

Right. This should not prevent you from enjoying your (excellent) 5DIII, though :P.

... Canon does not have BSI technology.


Um, I beg to differ: http://www.canonrumors.com/2012/01/patent-large-back-illuminated-sensor/. Canon does have BSI technology, and for LARGE form factor sensors as well, FF and APS-C!


This is a patent, not an actual sensor.

Canon does not have any BSI sensors in production, as Lee Jay implied.

Canon produces back-side illuminated CMOS sensors with 1.5 micron pixels (equivalent to 24,000x16,000 = 384MP on full-frame) for its compact cameras. 


These are likely Sony sensors, as Canon does not have BSI technology.

Canon does not use it's own sensors for compacts ... except for the 12mp sensor in the S100/S110 and G15.
This is the sensor, based on which Chipworks concluded that Canon has a 180nm (FSI) process already.

The 180nm process should start making appearances in DSLRs soon.
It appears that parts of the 6D sensor are already made on 180nm process, as vaguely confirmed by Canon Japan:
  • The newly developed CMOS sensor, introducing a process miniaturization in semiconductor process CMOS

It's interesting that Canon USA/Europe do not mention anything about that.

Based on the available info, though, I'd say that the 6D will end up having better image quality than the 5DIII.
Note that the rumors floating around are saying that only parts of the 6D sensor are made on 180nm.
So, the 6D sensor is essentially a 180nm/500nm hybrid.

The question is, are the new APS-C sensors from Canon going to be fully made on 180nm?
If they are 180nm/500nm hybrids, performance might not be all that different from current sensors.
 
But if they are fully made on 180nm, they are certainly going to match/beat the current 16mp Sony sensors.

Is anyone else wondering why there may/will be a new "naming scheme"?

Depends on what is meant by "naming scheme".

The '7D' name will not change, IMO, but it's certainly possible that the 'Mark XX' naming scheme might get retired.
Thus, instead of using the name '7D Mark II' for the 7D successor, Canon might use a new naming scheme.

Certainly a possibility.
I'd be taking the 7DII rumors with a grain of salt, though.

The 7D is a year older than the 60D and is seemingly the next candidate for an update.
The thing is, the 60D has been continuously lagging behind Nikon's D7000 in sales, even though it's been selling for less.
So, it might actually make more business sense for Canon to update the 60D first, not the 7D.

Either way, one of these two cameras will get an update early next year for sure.
And we'll get a new toy either way :P.

What does it mean "the sensor is currently in EOS 1DX" ??

It means that the 40+ mp sensor is put in a 1DX body for testing.
However, the expectation is that the body will be different when the high-MP camera becomes an actual product.

P.S. These are all rumors, of course.

In some ways, Canon is like Intel... Nikon like AMD... AMD once beat Intel to the 1Ghz mark, caught it napping, because Intel was both arrogant and lazy... but then it came back with a Bang and AMD is still playing catch up after a decade...

Err, you are forgetting that Nikon used to be the 800 pound gorilla in the industry, not Canon.
So, according to your analogy, Nikon is now coming back to raclaim their leading position.

Quote
Nikon is already feeling the pressure and competatively pricing it's products trying to get back market share...

Again, incorrect.

Recently, Canon has been (grossly?) overpricing their products - in what looks like a misguided attempt to position themselves as the Apple of the camera industry (or something like that).

To see the results of this overpricing strategy, though, just look into the last quarterly results from Canon and Nikon.

Last quarter, Canon's DSLR sales were down compared to 2011.
Canon also lowered their outlook for the year ... for a second time this year.

In comparison, Nikon's DSLR sales were up compared to 2011.
Nikon also revised their yearly projections ... upwards.

FYI, Canon projects sales of 8.8 million DSLR units in 2012 vs 7.1 million for Nikon.
If the last quarter becomes a trend, it won't take too many quarters before Nikon passes Canon as the industry leader.

So, expect Canon's overpricing strategy to be abandoned sometime next year - after they have had two-three more quarters like the last one.

They've telegraphed the big MP FF (to keep people from jumping to Nikon I suppose) ...


Canon hasn't telegraphed anything.

The 46mp figure is derived by scaling the resolution of the 7D/60D sensor to FF:
  • 18mp * 1.6 * 1.6 = 46.08mp

Not sure who thought that this was a good idea but it looks like wishful thinking to me.

40mp would be much more palatable, for example.
A 40mp sensor will be able to achieve UHD video resolution (3840 × 2160) with 2x2 pixel binning.
Canon is already doing 2x2 pixel binning on the 5DIII for HD video (hence the magic number 22mp).
And it would only make sense if they do the exact same thing on a high-MP camera.
This would require a 40mp sensor, though, not a 46mp sensor.
So, 40mp is actually more likely than 46mp for the high-MP camera.

The 46mp figure is not only not telegraphed by Canon but it's also a very weak [CR0] rumor.
