I dont care about how many pixels it has. Just improve high iso performance and dynamic range and I will buy it :)

You could get a full frame camera and crop the pictures to achieve that...

So much hand-wringing and over-the-top comments over basically a "filler" post that doesn't even carry a CR rating.

This is pure speculation folks. Nothing more.

However, I do particularly enjoy all the people who swear the won't buy a 70D unless it has the same sensor as a 7DII. I'm sure Canon would be quaking in their boots for fear that all those people who want to buy a 70D would have to buy a 7DII instead.

It is ridiculous if they put the same old 18 mpix sensor in the 70D!
I will definitely NOT buy 70D if it uses the same sensor.

Make at least a new sensor with better iso performance and better dynamic range!!!

I dont care about how many pixels it has. Just improve high iso performance and dynamic range and I will buy it :)

I agree. It's not the mega pixels, 18MP is actually very good number of pixels for an APS-C sensor. Sigh...  :-\ and all I wanted was a swivel screen, a shoulder display and above all a compelling sensor in a relatively small body. As other members have pointed out, the now dreaded 18MP sensor was actually good... 3 years ago!

I would rather be run over by a bus then believe that Canon would not improve on the 60D, especially after the 60Da.

Methinks you're taking your 60Ds too seriously then :)

maybe it´s just impossible to improve the sensor with canons current 500nm manufacturing process?

they have kept improving it for what 8-10 years?

so until canon has a new manufacturing process online they would have no other choice then using the same sensor.

I'm ready to accept that QE can be improved with getting rid of the current 500nm manufacturing process (http://www.chipworks.com/blog/technologyblog/2012/10/24/full-frame-dslr-cameras-canon-stays-the-course/), however Canon sensors have huge reading noise at low ISO (which limits the dynamic range).
http://www.sensorgen.info/

Can that also be improved just by changing the process?

I fear that Canon sensor tech cannot keep up with e.g. Sony not just because of a single reason but a multitude of reasons so probably the cure is also not that simple...but let's hope that they can fix it and don't introduce any new APS-C body with the old (by now basically obsolete) tech 18MP Canon sensor.

It's not the process per-se...its the technology. Sony switched away from using analog noise reduction to using digital noise reduction. Canon currently uses an analog CDS per pixel. Sony uses a variety of noise reduction techniques, including digital CDS, in their approach to CP-ADC. When an Exmor sensor is refreshed, a refresh read is done to determine the intrinsic electronic (dark current) signal. When counting that signal in CP-ADC, the count is negative, and that count for each pixel is stored in a cache per column. When the image signal is read out, the cached reset signal is intrinsically applied during image signal counting, effectively eliminating dark current noise. The fact that each column has it's own ADC operating in parallel, the ADC's can run at a lower clock, reducing downstream noise (one of the primary sources of Canon high ISO read noise, or at least it was until the current generation of Canon sensors). Additionally, since each column has its own ACD, vertical banding can be greatly reduced or eliminated as the differential between columns can be detected and compensated for.

I believe Canon has similar technology. The only way they could have achieved a 9.5fps readout of a 120mp sensor is with parallel ADC. Their press releases regarding that sensor clearly state that on-die parallel processing of some kind was used. Whether it is a form of CP-ADC with digital NR or something else that is still analog, I don't know...I've never found any explicit specs. Regardless...if Canon does move to a 180nm process, that die shrink would give them a hell of a lot of additional room on sensor die to include column-parallel electronics and basic image processing (i.e. noise reduction).

Some part of me actually wonders if some rumors are actually deliberately leaked by Canon as part of a stealth market research plan.

Why release the 70D then? Just merge the 2 lines with a 7DmkII.

I honestly think we'll see new sensors this time around. I also wouldn't be surprised to see the 7DII to be shown

Famous last words :-> ? ... you should do a search for the exact sentence, I remember it being written like this before the 600d & 650d.

Very good comment... does any full frame camera have a swirvel screen?

I believe Canon has similar technology.

well of course canon knows how to do it... it´s not some alien technology.  :)

they just have to do it.

but seeing all the fanboys being happy with mediocre sensors "it´s the photographer not the camera" .. why should canon hurry?
their "old stuff" is selling well.

no, it makes more sense for the management to maximize todays profit.
and if that backfires in a few years, they will work at other companys.
that is how these things usually work.. make the shareholder happy.. then walk to greener pastures before the cardhouse collapses.
 
but i think canon has a huge userbase and can afford it to be mediocre... for some time.

when i say "mediocre" is speak about sensors.. not cameras.
i still like the handling of canon cameras more.

it´s just that nikon user saw a image quality improvement in 2012... canon user not so much.

It isn't quite that simple. Realize that Sony owns a gagillion patents for sensor technology. Canon isn't just trying to milk their technology for all its worth...although in doing so they are certainly in a better financial position than Sony (who is barely better than junk bond status for their latest debt purchase). Canon has to find ways to do things similar to what Sony's done with Exmor...without violating Sony patents. Canon knows full well their technology is old, aged, and smelling pretty stinky by now.

I believe Canon's blunder is not that they are trying to suck their customers dry on crappy technology...Canon's blunder was not remaining innovative throughout the last five years or so, creating patents in lock-step with Sony. To play catch-up, Canon also has to play dodge-ball...they have to dodge Sony patents while concurrently trying to come up with their own, and with Sony owning so many balls to throw, Canon has a really difficult task on their hands.

70D goes back to the 6.3fps of 50D (now it is able to be a new feature again), gets the MFA of the 50D back again (to be trumpeted as a new feature improved over the 60D), keeps same or similar sensor as latest Rebel, adds some GPS/WiFi stuff, keeps flip screen of 60D.

Canon has the most patents of any camera company, & is #3 in the world when it comes to patents.

http://www.engadget.com/2012/01/11/ibm-maintains-top-spot-in-global-patent-rankings-canon-overtake/


Canon invests 10% of their revenue into R&D.

http://www.photographyblog.com/news/canon_registers_record_number_of_patents/


Sony has more invested in fabrication, but that doesn't mean they're doing more R&D or are ahead in patents.

If it will be, as you're saying, I'll be happy with 70D. Maybe new sensor..

http://dc.watch.impress.co.jp/docs/news/interview/20130124_584693.html


Can any provide a 'better-than-machine-translation' translation of this interview?  I'm struggling to make any sense of the automatic one but unfortunately do not speak japanese!  I'd be really interested to see what was ACTUALLY said.


Cheers!

Here is a better translation I found on another website...


DKW: As for the readers of DigiKame Watch, there are many who are waiting for the EOS 7D’s sucessor. Up through the release of last year’s major firmware update, there were many who felt that a new model with even better specs would be released shortly…
MM: Yes, they would be correct. For us, it’s about looking at what the camera has the potential to be and then adding that to what it can currently do. I do think the current model is still very attractive to buyers. And while we are, of course, developing its successor, it’ll be one that incorporates a certain number of innovative technologies. We will not be putting out a product with merely better specs, but one that has evolved into new territory. But then again, we’re not talking about something a long time from now either.

DKW: For example, your rival, Sony exceeded some of the limits that had been holding them back last year by asking themselves, “How far can we go?” They pursued the RX Series which is now in the market and delivered the goods, literaly, to their customers. And while Canon cameras will always be known for things like their high image quality, functionality, and great performance, somewhere along the line I get the impression that Canon began behaving as if it were the be-all and end-all in the camera world. The 7D seemed, in a sense, to be Canon’s attempt at showing its sensitivity and desire to go beyond its limits but, Mr. Maeda, do you personally have an interest in pursuing such “extreme” products like your competitors?

MM: Naturally, I want a camera to be something you put in your hand, peer out in the world with, and become happy with. And I absolutely want them to get smaller. I will refrain from commenting on other companies’ products, but speaking of our own, while cameras like the PowerShot S Series are considered small, they are still massive in my mind. We want to change that. And we will continue to pursue improvement in areas like production quality and the overall quality of our products in addition to high image quality.

thanks for that version of the translation, tim. also, good on the interviewer for being blunt and to the point. I'm a supporter of canon products but I do think they still need to look at themselves with a critical eye and work on continually improving, just like every company should.
