路边社泄漏文档。

个人感兴趣的是以下两点
8百万像素
22fps

8百万像素太少？但是使用最新技术制造的CMOS，将带来革命性的高iso表现。
>APS-C size CMOS sensor which is designed and manufactured by Canon, is the most light-sensitive and innovative sensor that Canon has developed to date.

22fps没用？但是为此装备了固定的！电子反光板。单反咣当咣当的机震将消失。想使用旁轴一样使用16-300的镜头群不再是梦想。
>- new eletronic mirror that is fixed in place

下面还有一大堆特性，除尘不再需要等等~自己去看。

CANON U.S.A. BRINGS IN NEW PROFESSIONAL LINE, 8.2-MEGAPIXEL, 22 FPS, APS-C EOS-1Di DIGITAL SLR EVOLUTION CONTINUED

Ultra-High FPS, New Eletronic Mirror, and Dual DIGIC 4 Image Processors Powers the EOS-1Di Making It The World’s Fastest Digital SLR

LAKE SUCCESS, N.Y., November 4, 2008 - The new 8.2-megapixel, APS-C Canon EOS-1Di Digital SLR camera brings the advantages of APS-C sensors to professionals. At a mind blowing 22 frames per second, the EOS-1Di digital SLR can fire huge eletronic-driven bursts of 320 Large JPEGs or 100 RAW files because it employs the new Dual DIGIC 4 image processor engine, providing enough computational horsepower to do parallel processing at a rate unmatched by any other digital SLR. The all-new 8.2 megapixel, APS-C size CMOS sensor which is designed and manufactured by Canon, is the most light-sensitive and innovative sensor that Canon has developed to date. It features the same gapless mircro lens array found in the new EOS-50D digital SLR. This results in exceptional image quality and an amazing ISO range of 50 to 6400 with extensions to ISO 25 and a highly usable ISO 12800.

The Canon EOS-1Di digital SLR is scheduled to begin shipping in early December and will have an estimated selling price of $2999. This makes the new camera a stunning bargain and a “must have” for pro shooters looking to add the versatility of a APS-C sensor to their line up.

“The new EOS-1Di digital SLR is an essential tool for professional sports photographers and photojournalists because of its exceptional speed and durability and it will attract a broad range of other professional and advanced amateur photographers because of its superior image quality and high low-light performance,” said Yuichi Ishizuka, senior vice president and general manager of the Consumer Imaging Group at Canon U.S.A. Inc. “In designing the EOS-1Di digital SLR, Canon responded to the requests of its many professional customers by adding new features that cater to their demanding needs. But at the same time, we have once again raised the bar for digital SLR cameras by introducing new technologies that only Canon can offer with the legendary EOS System.”

- I don’t like the use of APS-C. can we say it another way?
- we need to make another quote, this one was copied from previous release
- good start, just need to reword copied text

Evolved Mirror
- title has been selected, body need to be writen with following facts
- new eletronic mirror that is fixed in place
- eletronically controlled to make it transparent
- viewfinder is darken during continous shooting, not blacked out, also useable with movie mode and live view
- sensor is sealed from dust, no more anti-dust system required, impossible for dust to touch sensor
- negligible transmission loss due to light passing transparent mirror
- autofocus sensor alignment issues do not exist anymore
- eletronic mirror also replaces shutter, allows for shutters speeds up to 1/128,000 and no limits on x-sync
Developed and manufactured by Canon specifically for the EOS-1Di digital SLR, the camera’s new fully eletronic mirror replaces what many thought was unreplaceable.

- need a title and body to detail the advantages of 1.6x crop here

Dual “DIGIC 4″ Image Processors
Fulfilling the ultra-low noise, ultra-high image quality promise of the EOS-1Di digital SLR camera requires handling the enormous signal processing requirements of the camera’s 8.2-megapixel resolution and top continuous shooting speed of 22 frames per second. To accomplish this, Canon has incorporated two identical DIGIC 4 imaging engines into the camera for parallel (and hence, faster) signal processing. The CMOS sensor reads out to the dual “DIGIC 4″ processors simultaneously in eight channels. DIGIC 4 is the next generation of Canon’s proprietary image processing engine. This technology ensures the fine details and natural colors of images are optimally recorded and, as an added bonus, is responsible for the EOS-1Di SLR’s high-speed performance, faster signal processing and more efficient energy consumption.

Adding to the improved virtuosity of the images captured by the EOS-1Di digital SLR camera is the camera’s 16-bit Analog-to-Digital (A/D) conversion process. Able to recognize 65,536 colors per channel (four times the number of colors recognized by the EOS-1Ds Mark III Digital SLR camera’s 14-bit conversion capability), this new model is able to produce images with finer and more accurate gradations of tones and colors. Additionally, given the significantly larger number of image file created when shooting at high speed by the EOS-1Di digital SLR camera, Canon has provided compatibility with the new Ultra Direct Memory Access (UDMA) compact flash memory card specification, which enables ultra-high-speed data transfer to the card. Utilizing a UDMA compliant card doubles the data transfer speed compared to a conventional memory card, putting the new EOS-1Di Mark III on par with the 10 frames per second EOS-1D Mark III camera, even though the frame rate this new model is more than twice as fast.

- UDMA isn’t new anymore, might need to remove or reduce

Advanced Autofocus Technology
The EOS-1Di autofocus system has 45 AF points including 19 high-precision cross-type points and 26 Assist AF points. This new array allows the 19 cross-type points to be divided into groups of nine inner and nine outer focusing points plus a center point, which makes picking an individual focusing point much faster and easier than going through all 45. During manual AF point selection, the AF point area is expandable in two stages via Custom Function control.

Micro-adjustment feature allows for very fine changes in the AF point of focus for each lens type in use, along with the addition of adjustable focus-tracking sensitivity as another sophisticated new AF feature. Other new components in the AF system include the brand new eletronic mirror and the secondary image formation lens, both products of Canon’s vast expertise in optical engineering. Finally, the low-light sensitivity of the new AF sensor has been doubled to EV-1 for superior performance, compared with earlier EOS digital SLRs.

- we should say something about how the AF is even better than the 1D Mark III

固定で透明、電気信号で制御、連続撮影時暗くなるだけ。
どんな仕組みだろうか。ガンガンDCに近づくのは当然なことだけど、Mirrorを無くすまではまだまだか。

I agree with KJ on his last point.
“viewfinder is darken during continous shooting” That means you’re loosing some light due to lack of transparency… or maybe this is why the sensor is more light sensitive.
However, I remember reading somewhere that sport/action photojournalism will face a revolution soon… that could fit in that trend.
因为到达成像平面的光路要透过可控透明的反光镜所以要采用更加敏感的光敏器件？

Well, if it’s fake the person that wrote it definitely has experience with client feedback on copy. Looks like some of the stuff I deal with. Could be an ad or marketing guy’s “dream” camera.
I agree about the “wardriving”. A more likely scenario is someone found an open document or e-mail while jumping on a coworkers machine and forwarded it on. If it is real then maybe someone used the wardriving story as a way to cover their tracks.
I think it sounds pretty sweet. But if it were my dream camera I would have knocked the resolution up a little and given it the same ISO performance as 5DmkII. Maybe they figure most pros selling their shots to Sports Illustrated and various newspapers and editorial stock houses don’t need the resolution.
Since it does seem a little funky maybe it IS real. Canon has been doing some interesting things lately. : )
怀疑这不是真的。他的客户描述过这样的梦幻般的相机。

hh said: “…while the non-moving mirror may now supposedly protect the sensor from dust, doesn’t this now mean that we have to clean the mirror?”
Yeah I thought that. I suppose as it’s further away from the sensor the dust will be very blurred so might not be visible. But the only way to make cleaning completely unnecessary is to keep the lens in place at all times.
光敏传感器封装起来了，是不是意味着将来我们要清扫反光镜了？

>- viewfinder is darken during continous shooting, not blacked out, also useable with movie mode and live view

既然是darken，不是blacked out。说明这个电子反光板不是100%透明。肯定会损失iso。

但是如果不是continous shooting，也许这个电子反光板能有更高的反射率。

Canon以前搞过一个固定反光板的机器，透过反射比率是7:3。即使这样，最高可用iso也相当可观。

这个原文语焉不详。反正反光板也不动，我要是Canon的设计人员，干脆就把他一起封装起来算了~~~~

这个进化方向和我想象的方向不同。仍然需要反光镜的原因是测光和聚焦仍沿用SLR的成熟的机构。
可以控制反射折射比率的电子反光镜不可能做到厚度为0，除了损失入射光线的照度之外，还会因为透明反光镜基片上增加的至少3个界面引起的光折射和反射的影响。

反光镜已经造成影响了，再封装的话又要加更多的界面到光路中，而且封装玻璃又出来裸露的表面，还是需要清扫。只要是可以更换镜头的相机，清扫是不可避免的。

khonsou

今天的技术，AF和测光模块放在哪里问题都不大。保留反光板的原因，我认为最要紧的就1条：
光学取景。

反光镜厚度，既然Canon以前的那个胶片的固定反光镜单反能正常用，那这个问题应该解决了。

镜头和反光镜中间多层玻璃似乎问题不大。本来保护镜和CMOS中间，就是很多层玻璃~~~擦反光板前面的保护玻璃，或者擦反光镜，2选1，我挑后者。

否则（只封装CMOS的话），和现在区别不大，没有不需要除尘的理由。
现在CMOS就是封装的，擦CMOS，实际上是擦CMOS的低通滤镜。
所以这点可能有Bug。也是这个传闻中最不可信的地方。

AF放在哪里还不是无所谓的阶段。SLR的机构仍比DC的算法快速。
ViewFinder仍然是相对便宜可靠的机构，但并非不可以数码化。F828就是用一个LCD模仿五棱镜取景器的，比光学的更加WYSIWYG的。

所谓EVF，M4/3在搞。目前的效果还差的远。
