我抽空翻译几段重点部分。

反正意思就是几年之内都不会推出全画幅的X3机型，因为全画幅X3的数据处理量相当于中幅数码后背，但不是说永远不会。

SD-1M的下一个型号将是SD-1Q，这个感光器是现成的。

1、失真度更小的DP0；
2、加上增距镜的DP3q ，不仅图像质量不降低，甚至会更好；
3、改进的SPP算法。

值得等待。

求中文

演讲全文英文翻译出来了：

不是spp中的，是机身上的，dp2q在长时间曝光时，默认是开了长时间曝光降噪的，这样曝光时间越长，降噪所花的时间也就越长，拍星轨的话，就会断裂。希望适马在机身固件中加个关闭长时间曝光降噪的选项，需要的时候可以关闭。
不过，如果适马不加，说明dpq这代感光器本底噪音可能很大，不抹一下，实在不能直接出来见人。

Re: Yamaki's Presentation at CP + 2015 - Full Frame X3

Thank you for your compliments. Here is an unabridged version of Mr. Yamaki's talk. It's still half way through, till 21:45 of 39:44. If I have some time tomorrow, I'm going to complete the translation. Please enjoy this and wait to see the rest.

Thank you for coming today, and thank you for supporting our product and activities.

I'm giving two presentations about our new product at this CP+ 2015, and today, I'd like to talk about our new cameras.

Here is a box but there will be no surprising items. I'm not so resistant to the pressure, so I'd like to say that I'm talking only about previously announced new items.

We announced the new dp Quattro series, dp0. After the announcement, I've got lots of comments that say “it's crazy!” Yesterday, other company's staff talked to me saying “SIGMA is trying to maximize it's craziness, isn't it?” I said “No, it's not our intention.” I feel some weird atmosphere.

This is dp0. I'm going to talk about this in detail later. It's been a long time since we started selling the first DP1 that a lot of customers have wanted to buy a little wider version of DP1. Even I often feel the same way when I use DP1 personally. As DP1 can capture the detail, I encountered various cases that I feel if only I have a wider lens DP. However, we couldn't decide how wide it is possible as business.

First, we started making a wide converter lens to achieve the 21mm focal length. But it was difficult because the image quality of the corners was blurred. I know that a wide converter lens is convenient, so I don't mean to say that it is useless. However, thinking about the concept of the DP, it might not be good to sell a wide converter lens at first. So we abandoned the project.

Whenever I travel around the world for business, I have been asked about the wider DP for a long time. So we finally started the project officially last year to make the wider DP with a special lens.

Today, I'd like to introduce this dp0 and dp3 which will be available soon. But before that, I want to talk about the concept of the dp Quattro series. This might share the same information that I talked last year, but please let me explain the idea.

The goal of the dp Quattro is to achieve the image quality with a tangible and realistic feel. We do not compete to increase the pixel number, but to acquire the higher image quality. My hope is to achieve the image quality which the medium sized film cameras used to have.

This is an off-topic episode, but Foveon's chief engineer likes to shoot with medium size film camera along with developing the image sensors. He is a unique guy. But unfortunately he is so busy lately that he has less chances to go out shooting. Anyway, to reach the goal, we SIGMA team and Foveon team collaborate each other with the same direction.

So how to acquire the “rich” image quality? We think it is necessary to get minute detail and stable detail for any kinds of objects. For DP camera, we think three factors are important. The first is the Foveon X3 image sensor. The second is the specially designed high quality lens. The third is the fixed, not interchangeable, lens which uses a lens shutter with less vibration and is aligned perfectly to the image sensor. An interchangeable lens camera relies its image quality on the accuracy of the lens mount as they align the image sensor to the camera mount and align each lens to the lens mount. On the other hand, this fixed lens camera is designed to adjust the matching of the lens and the image sensor from the center to the corners. So, the lens is physically “attached” to the image sensor to achieve the perfect resolution anywhere on the image. This is the characteristic of the lens fixed camera.

You might hear this many times, but please let me explain the Foveon X3 image sensor.

This is a normal Bayer sensor, which can not distinguish the color difference so it uses the RGB color filter to obtain color information at each pixel. Then, it compliment color information by calculation and make a full color image. This Bayer sensor is named after its inventor Mr. Bayer. We Japanese call him “Bay-yah,” but actually the pronunciation is “Buy-yah.” I heard his bereaved family also want to be called “Buy-yah,” anyway.

The next is the Foveon sensor. This sensor can capture different wave lengths depending on the depth of the silicon. Here is also what I talked last year. For normal color filter sensor, the green shares 50% of the pixels and the blue and the red share 25% each. On the contrary, the Foveon sensor can capture all RGB at any pixel. The reason why normal sensor spares 50% of the pixels for green is that human eyes are the most sensitive to green. The shorter wave length is blue, the middle is green, and the longer is red. Longer than red is infrared, and shorter than blue is ultra violet. Both human eyes can't see. As Foveon sensor can captures green at all pixels, if the number of the pixel is the same, Foveon has twice as high resolution as Bayer sensor. This is the principle of the Foveon sensor.

I'm surprised that a lot of audience here has Quattro cameras, as I have few chance to see someone with a Quattro camera on the road. Thank you so much.

The characteristics of the Quattro sensor is that on the top layer, it captures the detail of the object. It consists of 20 mega pixels. For colors, the top, the middle, and the bottom layers captures each color. The middle and the bottom layers are four times bigger than the top layer. As Foveon is three layer sensor, the data size is triple, and because of this, the processing, transmitting, and writing the data get slow. However, Quattro can solve this problem. Anther difficulty is that the wiring becomes complicated if we maintain the previous structure. The size of the photo diode becomes smaller and the amount of intake of light also becomes worse. By using the Quattro 1:1:4 structure, we do not sacrifice the intake, and could maintain the detail of Foveon X3.

These are the specifications of the Quattro sensor, which you might be aware of. The total number of the photo diodes is 29,400,000. It is comparable to the 39,000,000 pixels Bayer sensor in terms of the resolution.

With the Foveon sensor, whatever the object is, you could get the detailed image. I think the uniqueness of the photography is its reality, compared to other arts such as paintings. We would like to pursue the expression which has reality as if it exists in front of you. Therefore, it is necessary to avoid unnatural resolution, such as some area is detailed but other is not.

Here is a resolution chart taken by dp2 Quattro and 36 megapixel Bayer sensor. Both sensors' resolution is quite good, but on the Bayer sensor, the brightness resolution and the color resolution don't match. Therefore, there is false color. On the other hand, even it's structure is unique 1:1:4, Quattro's final image has no false color, that is, you can obtain a clear and clean image. This is the characteristic of Foveon, and with this image, we could achieve the “middle size quality.” These are the technological background of Foveon.

Before I started preparing this presentation, I asked some questions on ※※※※※※※. Someone asked me “Is there any room to improve the quality of the Quattro sensor?” He has been using SIGMA camera for a long time, so he knows a lot. I felt it's a really critical question.

I have something to apologize for users. Sigma Photo Pro ver. 6.0 was released with dp2 Quattro, which is designed to develop Quattro file. Current version is 6.2. But previously, there are some errors and unoptimized processes on the SPP. For example, if you take a long exposure photo, the noise reduction works too strongly, so the detail had disappeared. I knew a lot of users wanted to take a detailed long exposure, but there was a bug on the SPP.

The second is that there was too much noise reduction on the shadow area. As I said, we want to make a high resolution camera with all kinds of objects. But there was a problem, though it's been fixed already. Finally, as we developed the new 1:1:4 structured sensor, which is totally different from its predecessors, we didn't understand everything and found there were ways to improve the image quality.

We have updated and keep updating the firmware to optimize the Quattro sensor. The next version SPP 6.2.1 is coming soon. We are planning to release this at the end of February. If you have a Quattro file, please download the new version, and re-develop it. I think a lot of users were worried about the Quattro image, but I'm confident that SPP 6.2.1 will satisfy you. We will keep working to improve the Quattro image and developing the appropriate algorithm.

Another question is “Can SPP processing become faster?” and “Are you going to sell a high speed PC for Quattro development?” Of course, we are not planning to sell a PC, but we understand that the slow processing speed is a problem. We have improved the speed quite a lot at the SPP version 6.2. However, it is also true that we have prioritized the processing quality rather than the speed. So we will focus more on the processing speed and put much effort to improve the usability of SPP.

I'm going to talk about the new product. The first is dp3 Quattro. As you know, it has 50mm lens, which is equivalent to 75mm on a full-frame. dp1 is equivalent to 28mm, and dp2 is equivalent to 45mm. In the series, dp3 is positioned as a middle telephoto lens camera.

Now, we have a new ultra-wide lens dp0. To say the truth, I'm a little worried about the naming of dp0. Someone wrote on ※※※※※※※ that if there will be a wider lens, will it be dp minus 1? The other said if there were 35mm dp, would it be dp 1.5? Even SIGMA couldn't release something 1.5, so I was wondering the name of dp0. But finally, as I'll talk about this later, the distortion of dp0 is almost zero, so it's wider than dp1, and zero distortion, dp0 represents these ideas.

Anyway, let's talk about dp3. As some of the DP3 users might notice, it has a really sharp lens. It can give a real DP quality image. The design of the lens is really classical. It consists of a double-Gauss master lens with a converter. Because its focal length is standard, we can choose a classic lens design, but we put the cutting-edge glass element into the classic design, and manufacture it at the most sophisticated factory. So it achieves the ideal performance of its design, and the yield rate is also high. A lot of users appreciate its image quality, saying it can take sharper image. Compared to all SIGMA lenses, this dp3 lens is one of the sharpest lens.

Updating to Quattro, we improved the AF speed. It's 20 to 30% faster than the previous DP3 Merrill. dp camera has a problem on focus at low light, but we also improved this issue. In addition, dp2 and dp1 Quattro's AF will improve with a new firmware, which will be released at the end of February. The exact day has not been decided yet though. So for Quattro users, please download the new firmware and try it.

The release of dp3 Quattro is in March. So, please think about it.

We also announced the 1.2 times conversion lens FT-1201 for dp3 Quattro. The equivalent focal length will become 90mm, and as it's a front converter, the F-stop is the same 2.8. The concept of this is the converter that doesn't deteriorate the image quality of the dp3 master lens.

This is the picture of the converter. As you can touch there, it's a big converter consisting of three groups and four elements. Here is the MTF chart. The left side is the dp3's master lens, and the right is the dp3 with the converter. The left side of the chart shows the center of the lens, and the right side is the corner. The red line represents low frequency, such as a thick big object, and the green line represents high frequency, small objects. From the center to the corners, both lines are flat and the performance is high.

With the converter, the performance at the center is the same. From the center to the corner, the performance is stable. But please check the far right. At the corner, the performance is actually higher than the master lens. I was wondering whether it is true, so asked to the designer. He said it's a coincidence. What a nice coincidence to get a better performance. I wouldn't say that all performance is better than the master lens, but the MTF chart is like this.

The picture of dp3 with the converter is here. The original lens consists of 10 elements, and the converter has four elements, which means 14 elements. As the body of the dp is thin, it becomes a front heavy camera. You might be worried about the balance, but please feel at ease, we have a LCD view finder. With this finder, the balance of the camera gets better.

Let me talk about the finder a little. The part which attaches to the camera body is called bracket. This part is made by aluminum machining, so it's really solid. The eyepiece lens is optical glass, which is as same as an interchangeable lens. The diopter adjustment uses an advance helicoid, so its feel is as sticky as a manual focus lens.

Here is dp3 with the converter and the view finder. As this becomes 90mm, it is better to attach the eyepiece to your left eye to avoid the camera shake. It will be a good portrait camera. But to say the truth, I can't understand what I'm doing on this camera, seeing its form.

The rest of Mr. Yamaki's talk is coming soon.

我现在的i7 24G内存，速度的问题是出在i7不够给力上。

要长时间曝光的降噪，那要两颗以上的至强处理器了吧。

好像问题出在SPP，下一版本的新SPP中应该是不存在这个问题了。

“For example, if you take a long exposure photo, the noise reduction works too strongly, so the detail had

disappeared. I knew a lot of users wanted to take a detailed long exposure, but there was a bug on the SPP.
”

现在DPq 可以同时四个相机同步遥控曝光了。要是能远程拍摄前看到多个机位的情况，就可玩了。

或者就是类似现在很多MSK相机中都具备的Wifi功能，直接通过wifi传数据到pad或电脑上显示全图，不过这个对电力消耗比较大。 本帖最后由 vbvcvj 于 2015-2-14 21:24 编辑

是，山木说，在这一点上没有技术问题，DPq是可以用 Capture Pro 链接电※※制拍摄的。现在平板功能那么强大，DPq有这个就好玩多了。

关键是可以在拍摄前看。 本帖最后由 diamondring 于 2015-2-14 21:23 编辑

多谢分享

我估计diamondring指的是tether功能，也就是目前只有SD1/m专有的Capture Pro软件的功能，通过USB连接电脑和相机，拍摄后自动在电脑显示屏中显示图像，用于放大查看。 本帖最后由 vbvcvj 于 2015-2-14 21:13 编辑

DP一直有LiveView，否则怎么从液晶屏取景？

下一代SD在开发中但没有透露细节。

Re: Yamaki's Presentation at CP   2015 - Full Frame X3

Hi, I'm a native Japanese and I'm not so good at writing in English.

Anyway, Mr. Yamaki talked about FF foveon like this.

"We are often asked about FF foveon, but basically it's no comment. If you ask me there will be a FF foveon next month, I'd say no. But it doesn't mean there will be no FF foveon in the future. I can't say yes or no. Whant I want to say is that there are a lot of challenges when we make FF foveon. Even with Quattro 1:1:4 structure, the data size will become huge. The data processing time and writing time will be a problem. More difficult problem is lens. The bigger the image cirlce, the more difficult to design the optics. At present, it is true that the APS-C size is a well-balanced size. As you see, the normal bayer sensor can get only half resolution as foveon can take. So for bayer sensor, there is only one solution to increase the resolution: increasing the sensor size. Because there is a threshold to minimize the pixel pitch. I believe that with a smaller sensor, foveon is the only way to achieve the higher resolution, and APS-C foveon can be comparable to FF bayer sensor. If we make FF foveon, considering the data size and other things, it will behave something like middle sized digital back. Please keep in mind these things. But basically for FF foveon, it's no comment."

He also talked about next SD camera. They are working hard but still he can't say anything about it. The spec, name, everything is not decided.

Another information is

Next SPP ver. 6.2.1 will come by the end of this month. By using this, you can get higher resolution with Quattro sensor.

He wants to improve the processing speed of SPP.

New Quattro firmware will come by the end of this month. AF will improve at low light.

dp3 and it's conversion lens will come in March.

dp0 will come at the beginning of summer.

一定要LiveView，那天山木曾经非正式地应诺DPq可以加上LiveView，他说技术上没有问题，只是之前没有想会有人要。

我等一干人还在等呢…………。

这个消息有点激动人心，135全幅的X3数码后背？SD-Q？莫非走仙娜M系列的路子？不过还是拜托接近小山木的人士传个话，如果法兰距是SD40多毫米的法兰距就没什么意思了，因为目前绝大多数罗敦司德和施耐德数码头都没法用，尤其是广角头无穷远不能合焦。胶片头焦距倒是够用，可是像场太大，广角大打折扣。如果用135系统的镜头，像场不够，也就谈不上什么“后背”了。全画幅的DP-Q能摘下镜头本身就是个X3数码后背，不是吗？

适马进步得谨慎，，应学学宾得弯道超车，，直接上中画幅645，，然后才全画幅

一个有极端限制的感光元件技术，注定了即使做得再便携全面也没法胜任全天候的拍摄。

适马的相机业务就是拿镜头养的，在传感器上不断创新也是一个试错的过程，没那么强烈的功利心，本来是十分可敬的经营态度。

反过来对一个产品有兴趣就关注，没兴趣就不买了事，何苦死了活了的。

奇葩。

DP0+光学取景器

Dp3Q +FT-1201 1.2X增距器 相当于90mm的DP4

DPXQ到SD1Q这1轮走完了再买1断. 全副就出来了.数据量大用12比特也行.我DPXM隔代才好升级.

它如果搞个1寸底的卡片变焦机1000-1200W像素，说不定会热卖得一塌糊涂。

明显可以把机身做得正常点，便携点，但适马偏偏要搞个弯的奇葩机身，再这样下去，就离死不远了。拥有先进技术，有可能不是成功者，而是被拍死在沙滩上开拓者而已。漠视用户对变焦卡片的需求，自作主张认为用户不需要，真以为自己是老乔，可以改变世界了。这次的发布非常令人失望。没有令人眼前一亮的产品。

竟然还可以这样！

全幅X3，仍然没有明确的方案，等到孙子当爹的时候吧。

有这等好事？
看到间隔摄影时间缩短到4秒，不知道长时间曝光降噪取消选项这个功能有没有做在新的固件里面？这样就可以拍星轨了。

快门线dpq已经有了，放大对焦已经有了（依使用em1、nex7等机器峰值对焦的经验，dpq上的峰值对焦还是不要报太高希望了吧）
