Canon Rumour

I WOULD buy a Canon with a Leica Mount, but I would keep the DMR. Leica would be smart to do this if they are able because they do not have the technical or financial resources to do so on their own. by doing this, Leica could concentrate on Lens Design and manufacture.

 

Canon is NOT Minolta, and it would not ruin Leica.

 

Just my Two Cents.

 

I own a Canon 1Ds and while the results are excellent, I would still STRONGLY prefer a DSLR that is based on the Leica R9, since the Leica is much more convenient to use than any other camera I know!

Fortunately, all these Canon - Leica rumors are nonsense anyway :D

Here's a wake up rumor for all you Canon fans who just purchase a new 40D, hot off a Chinese website is the info of the Canon 50D its replacement after how long? 4-5 months? Rumored (and supposedly seen at the Olympics) it's 15.1 MP, brighter screen, Digic IV. To be announced this week. Our Canon rep confirmed an announcement this week but told me it was "none of my business" when I asked him what. If this is true aren't you Canon users lucky to be buying replaceable cameras every few months? Glad my M8 is upgradable and will at least have a decent run and give me some value before it is replaced.:eek:

10 months as of now, probably 12 months when the 50D becomes available, but still, it would be a rather short product cycle, about 18 months being typical for Canon’s two-digit models. The announcement your Canon rep referred to will probably concern the new A-class PowerShot models.

I completely agree. It would make more sense for Leica to abandon its SLR range and make lenses for Canon mounts. Interestingly, Zeiss has chosen Nikon, Pentax, Sony and M42 for its mounts but not Canon, so there is a gap in the market.....

wow i could then mount my old zeiss(contax/yashica) to leica.

with the same zeiss-eos-adapter(chipped for focusconfirm)

there is even a zeiss(c/y) to leica M-adapter.

if you cant wait for FF-leica-R:

use your leica or zeiss(contax/yashica) with these lens-modifications(way back to original is possible)

M42 for its mounts but not Canon,

M42 is the Zeiss´solution for Canon users. Nikon, Pentax seems to "support" the use of their mount on Zeiss lenses. Canon not.

Wrong. 50D as I said.:eek:

The Canon 50D was announced officially by Canon today. It is on their website, Steve'sDigicams and DPReview sites. It was leaked by a Chinese Canon site last week because reportedly there were Canon photogs using the 50D at the Olympics.:D

How is a consumer Canon of any interest to us, though?

 

perhaps because of the following

 

 

"The 50D sensor and image processing are a major step forward in what has been a multi-year strategy for Canon to take sensor technology to the limits of physics, simultaneously achieving higher ISOs, lower noise and higher dynamic range. Note Chuck Westall’s announcement that the 50D sensor has 1 to 1 and a half stops better noise than the 40D sensor despite the smaller pixels. Several core strategies have been pursued simultaneously for this:

 

Reducing the micro lens gap to capture all the light hitting the sensor. This has been highlighted in the 40D, 1D III and 1Ds III sensors and the new 50D sensor now achieves effective 100% coverage. Only very minor improvements are expected from this point on (e.g. shaping the lenses towards the corners of the frame to capture angled light.

Reducing the noise level of each pixel. Canon have made changes over several generations of sensors to achieve this, bringing the amplifiers closer to each pixel, changing micro-circuit configuration and lowering voltages so the sensor runs colder. Again the design of the 50D is a big step forward here from the 40D and 1D III etc. Canon have one more big jump lined up, with low voltage cold running CMOS designs to gain at least an additional stop in lower noise at higher ISOs or long exposures.

Better digital noise reduction. These are the changes in DIGIC noise processing. First with the Chroma Noise reduction in DIGIC III and now with more advanced multi-level noise reduction options in DIGIC IV. Canon believe they have made most of the gains possible via processing algorithms but do still have some areas to develop. The next focus will be faster noise reduction processing so that it does not come at an impact on frame burst rates (look to the 1D3 replacement for example)

Pixel binning for high ISOs. A new technology enabled by the complexity and processing power of DIGIC IV where they can bin 2, 4 or 8 pixels together at the raw level and average out the noise between them. This is seen by Canon as a key technology in balancing very high resolution sensors (in the 50mp range) with low noise at very high ISOs. Right now they are not pushing this too much with the 50D so as to not create confusion in the market (they see more potential for the technology as sensors get larger and in the pro-market).

Increased image resolution – This is a newer strategy (most evident on the 450D where they have changed the anti-aliasing filter (thinner and closer etc) so as to achieve a crisper image per pixel without loosing the benefits of anti-aliasing filter on diagonal edges etc.. The 50D has the same technology. One further option for the future is for Canon to drop the anti aliasing physical filter and do it in a future DIGIC generation where there can be smarter allocation of colour values than the blurring achieved by a light based filter.

Increased raw bit depth for improved dynamic range. Here Canon have made the jump to 14 bit and will move to 16 bit in their future sensor technology generations. Canon see the main usage of extra bit depth as providing the dynamic range to translate the sensor image into a printable or viewable image with a higher dynamic range. In other words mapping the 14 or 16 bits into an 8 bit viewable or printable image that mimics the dynamic range in the scene.

Dynamic range preservation options – Canon are putting a lot of focus into how to provide the photographer with the best options for preserving the dynamic range of the original image in both a RAW file and the 8 bit JPEG. The highlight tone preservation option on the 40D, 1D III etc was the first step. The new 'automatic brightness' options in the 50D are another, where they try and optimise the brightness of various parts of the image to reduce the dullness from shadows. Canon are planning much more in this area, down to the equivalent of varying the ISO level across the different parts of the sensor when the image is taken (easier in live view mode of course).

So what does this mean?

 

The 50D DIGIC IV sensor and image processing technology is felt to be Canon’s biggest jump in many years.

 

The same technology will allow a 21-25mp FF sensor to have 1 to 1.5 stops better noise performance than the 3 year old 12mp sensor in the 5D.

 

Canon are not going to watch market share be lost in the 1D range to Nikon and are actively planning to incorporate this technology in the 1 series as well, sooner than many might expect.

 

Canon have hit the limits on light gathering but believe there is a good 1 to 1.5 stops lower noise still to be achieved at the physical electrical level before they reach the limits of physics (background noise due to heat etc) and are working on the circuit design for this (native 12800 being one goal)

 

The other technologies in the image processing, pixel binning, dynamic range preservation space are seen as all offering room for significant further improvement in the image delivered to the photographer. Canon have a vision where the imagine processing is so good that it is capable of transparently capturing the dynamic range of a scene and converting it into a JPEG in a way that for most consumers cuts out blown highlights and detail lost in shadow without further processing."

Haven't seen an improvement in photographic abilities of late, still the same old tired stuff despite what the cameras are about

 

 

 

 

 

 

 

 

 

Why are people still responding to this made up rumour?

Aren't you the OP ????

 

Of course no foundation to the original, but like a virus the thread has mutated .

 

I am merely responding to the previous poster !

So in many respects Leica with its 2- and 3-year-old cameras is still ahead of this "advanced" CMOS sensor. I can hardly wait for Photokina.

At the 50D's press conference in Tokyo, Canon's chief executive of their Image Communication Products Operations Division, Masaya Maeda, has talked about another DSLR they'll introduce before the Photokina. Of course, you have to know Japanese in order to understand what he says. LOL

 

Before Leica shows their mockup on 15/09, Sony will introduce their FF model with a 16-35 Zeiss and a bunch of other stuff as well. We'll keep Andy busy for sure.
