The SIGMA Corporation is pleased to announce the SIGMA sd Quattro and SIGMA sd Quattro H, two new high-image-quality digital cameras that incorporate the Foveon X3 direct image sensor (generation name: “Quattro”).

Building on the concept of the SIGMA SD1 Merrill, the SIGMA sd Quattro and SIGMA sd Quattro H feature a mirrorless structure and use interchangeable lenses. The two new cameras are as compact and lightweight as cameras in the SIGMA dp Quattro series and offer the same level of outstanding image quality. Featuring the SIGMA SA mount, the two new cameras are compatible with all of the SIGMA GLOBAL VISION lenses in the Contemporary, Art and Sports lines, and they are designed to take full advantage of these lenses’ superb optical performance.
The SIGMA sd Quattro features an APS-C size sensor and offers medium-format image quality with 39 megapixels. The SIGMA sd Quattro H features an APS-H size sensor measuring 26.6 x 17.9mm. This new, larger Foveon sensor delivers high resolution of 51 megapixels, for even more detailed expressive power.
在SD1M的概念基础上,sd Quattro和sd Quattro H 使用可互换的镜头。 这两个新相机和相机一样小巧轻便的,并提供相同级别的出色的图像质量。 两个新照相机兼容所有的Contemporary, Art and Sports 镜头,旨在充分利用这些镜头的出色的光学性能。

[Key features]

Foveon X3 Quattro direct image sensor
Leveraging the light absorption characteristics of silicon, the Foveon X3 Quattro direct image sensor comprises three layers of photodiodes, each at a different depth within the silicon and each corresponding to a different RGB color. Since it is the only sensor to use this superior vertical color separation technology, it is also the world’s only direct image sensor. Requiring no low-pass filter needed to correct the interference caused by a color filter array, the Foveon X3 Quattro direct image sensor is able to take full advantage of the information carried by light, including color information. The sensor features a pixel ratio of 1:1:4 in the bottom, middle, and top layers and applies the brightness data captured by the top layer to the middle and bottom layers. This unique structure makes possible fast resolution and high-speed data processing.
（这段是描述1：1：4的传感器，略过）

Two sensor sizes available
Other cameras typically use a single-layer photo sensor covered by a Bayer filter mosaic, which comprises 50% green, 25% blue, and 25% red squares. In contrast, the Foveon X3 Quattro direct image sensor uses no low-pass filter and is able to capture 100% of the data for blue, green, and red in each of its three layers. Due to this unique structure, the Foveon X3 Quattro direct image sensor can generate up to twice the resolution data of sensors using a Bayer filter. The SIGMA sd Quattro has an APS-C-size sensor with 19.6 megapixels in its top layer, giving it an equivalent total of approximately 39 megapixels and the outstanding image quality expected of a medium format camera. The SIGMA sd Quattro H features a newly developed APS-H-size sensor (26.6 x 17.9mm) with 25.5 megapixels in its top layer for an equivalent total of approximately 51 megapixels. This larger sensor takes Foveon image quality to the next level, delivering more detailed images than ever before.

Dual TRUE III for high-speed processing of high-volume data
TRUE (Three-layer Responsive Ultimate Engine) III is the dedicated image processing engine for the Foveon X3 Quattro direct image sensor. SIGMA’s original algorithm processes data without loss of color detail or other image degeneration to deliver extremely detailed image expression with a noticeable 3D pop. In addition, by using two separate TRUE III engines, the camera is able to process data from the Foveon X3 Quattro direct image sensor at extremely high speed.
（TRUE III 处理器能更快速进行图像处理了）

New Super-Fine Detail exposure mode
The new Super-Fine Detail (SFD) exposure mode brings out the full performance of the Foveon X3 Quattro direct image sensor. One push of the shutter generates seven different exposures, creating RAW data in the X3I file format. Using this data with the SIGMA Photo Pro software package, the photographer can create noiseless images with an extensive dynamic range. With this new mode, the more detailed imaging potential of the Foveon X3 Quattro direct image sensor is fully leveraged. From each X3I file, individual X3F files may also be generated. The value of SFD exposure mode is especially apparent in studio photography.
Note: To prevent camera shake, SIGMA recommends the use of a tripod.
新超细节曝光模式
新超详细(SFD)曝光模式带来的充分表现Foveon X3 Quattro图像传感器。 一次快门产生七种不同的曝光,X3I（新文件格式）文件中创建原始数据格式。 使用这个数据与SPP,摄影师可以创建无噪点图像和一个广泛的动态范围。从每个X3I文件,也可生成X3F文件。 SFD曝光的价值模式在工作室摄影表现得尤为明显。
注意:为了防止相机抖动,建议使用三脚架。

Combination of two AF detection methods
Phase detection AF is superior for speed performance, while contract detection AF is superior for focusing accuracy. Combining these two methods in a single system delivers AF that is fast and precise at the same time. In addition, this approach to autofocus takes full advantage of the characteristics of high-performance lenses. The Single AF mode is optimal for everyday photography, while the Continuous AF mode is optimal for focusing on a moving object. In the latter mode, pressing the shutter button halfway causes autofocus to operate continuously, while Movement Prediction AF operates at the same time for more accurate autofocusing. A variety of other AF modes are also available. 9-Point Selection AF mode allows the user to select among nine focus frames. Free Movement AF mode allows the user to select the focus frame with high precision. Face Detection AF mode detects human faces and prioritizes focusing on them. The AF assist light incorporated in the camera body makes possible the use of AF even in low-light conditions.

Focus peaking function
This function puts a colored outline (white, black, red, or yellow) around the subject in the viewfinder for instant confirmation of the person or object currently in focus.
（加入了新对焦方法，相位、反差、峰值，九点选择对焦模式允许用户选择在9个重点帧。 自动AF模式允许用户选择重点帧。 人脸检测自动对焦模式检测人脸并重点关注他们。）

High-resolution electronic viewfinder
The high-resolution 2.36 mega-pixel electronic viewfinder features near-100% viewfinder coverage and a 1.09 magnification ratio. The viewfinder incorporates three lenses with the outermost lens specially coated to ensure a clear field of view. Using a switch next to the viewfinder, the user can toggle between displaying the image in the viewfinder and the monitor. In AUTO mode, the camera automatically switches to the viewfinder display when the user is looking through it and to the monitor when he or she is not. This mode allows seamless use of the viewfinder to take photographs and use of the monitor to access settings and confirm results. For extra convenience, many functions of the monitor are available via the electronic viewfinder itself, such as setting values, grid lines, electronic level, zoom, focus peaking and more.

Dual monitors
In addition to the 1.62 mega-pixel 3.0 inch TFT LCD main monitor, the rear of the camera features a sub-monitor that displays the number of remaining shots on the SD card, shutter speed, aperture value, ISO level, and more. This extra monitor makes it easy to watch the live view and confirm key information at the same time. A sheet of special material lies between the two LCDs and the protective glass that covers them. This sheet prevents air pockets from forming and minimizes reflections, ensuring excellent display visibility in sunlight.

Intuitive user interface helps user focus attention on creative work
Building on the success of previous SIGMA user interfaces, the new UI is more intuitive than ever. Located next to the shutter button, the Quick Set button provides instant access to the Quick Set Menu, which allows the user to quickly adjust commonly used settings while continuing to look through the viewfinder. Located on the top of the body, the LOCK switch prevents the accidental pressing of buttons, helping keep the user’s attention on the creative work. The buttons that are locked with this switch may also be customized by the user. Located on the rear of the camera near the selector are several controls for commonly used functions. Easily accessed with the thumb of the right hand, they include the menu button, focus frame button, and AEL/AF button with lever.
（操作界面大升级）

Quick Set Menu
Located next to the shutter button, the Quick Set button provides instant access to eight commonly used functions, including aspect ratio, ISO, white balance, and color mode. The user can quickly adjust settings using the selector and front and rear dials. Users can also customize the functions included in the Quick Set Menu and the order in which they appear.

14-bit RAW data
RAW data records the light information captured by the Foveon X3 Quattro direct image sensor. Using 14-bit (16,384 gradations) signal processing to convert the analog output signal to digital results in photographic data with fine gradations that effectively represent the smooth, natural gradations of the original subject. RAW data uses lossless compression that prevents image degradation. Moreover, processing RAW data with SIGMA Photo Pro results in images with incomparable natural balance.
（能储存14-bit的RAW文件，适马的画质追求……）

Continuous shooting of up to 14 images in RAW format
The DDR III high-speed, high-volume memory is approximately twice the capacity of that of the SIGMA dp Quattro. This allows the SIGMA sd Quattro to capture up to 14 RAW images (X3F files) in High size during continuous shooting (SIGMA sd Quattro H: up to 10 images). Leveraging high-speed data transfer and processing, the SIGMA sd Quattro offers a continuous shooting speed of up to 3.6 frames per second (SIGMA sd Quattro H: up to 3.8 frames per second). As a further option, when Low size is used, the SIGMA sd Quattro offers a continuous shooting speed of up to 5.1 frames per second and continuous shooting of up to 28 images (SIGMA sd Quattro H: up to 20 images).
（可连续拍摄14bit图像原始格式）

RAW onboard data processing
The camera can process RAW data (X3F files) into JPEGs without the need for a personal computer. The user can adjust the exposure correction, white balance, color mode, and aspect ratio while viewing the photographs on the LCD monitor.
（机内自带SPP处理软件，一步到位）

High-resolution Super-High size images
A variety of file sizes is available to accommodate a wide range of user needs. Using High-size files brings out the best performance from the image sensor, while using Low-size files increases the number of shots that can be stored in memory. In both of these file sizes, the camera can simultaneously create RAW and JPEG data. In addition, the camera can create JPEG files in S-HI size (SIGMA sd Quattro: 39 megapixels; SIGMA sd Quattro H: 51 megapixels), appropriate for large prints, as well as in S-LO size, which is ideal for online sharing.
（不同大小规格的图像存储供选择，反正都是用最大的……）

Aspect ratio selection
To accommodate various photographic needs, six different aspect ratios are available, including 3:2 (standard), 1:1 (square), 21:9 (similar to cinema widescreen), and 7:6 (similar to 6×7 camera format). When using an aspect ratio other than 3:2, the user may select a black or semi-transparent frame. The semi-transparent frame can serve as a sportsfinder, allowing the user to monitor activity outside the frame. The aspect ratio of images recorded as RAW data can also be changed in SIGMA Photo Pro.
(不同长宽比的拍摄规格，比如21：9）

Exclusive SIGMA Photo Pro software
SIGMA Photo Pro makes possible intuitive processing of RAW data, leveraging the full power of the information captured by the Foveon X3 Quattro direct image sensor. Operation is easy: the user simply adjusts horizontal sliders while viewing the photographs to create images that perfectly match his or her vision. In addition, the software turns X3I files created using the camera’s Super-Fine Detail function into high-resolution, noiseless images with outstanding dynamic range. Various modes allow the user to take full advantage of the image sensor’s fine tones and gradations and create monochrome images of impressive depth.
（独家SPP,自家的后期软件）
Higher-precision white balance
A new algorithm enhances the precision of auto white balance, even optimizing white balance in images with multiple light sources. The Auto (Lighting Source Priority) mode leaves the color of light sources intact for extra atmosphere, while the Auto (Default) mode allows the camera to automatically make white balance adjustments. In total, twelve white balance modes are available, including three custom modes. It is also possible to adjust white balance based on the specific image and to set the color temperature in Kelvin. Moreover, each white balance mode can be fine-tuned for detailed correction of white balance and creative filter effects.
更高的精确度,白平衡
新算法提高了精度自动白平衡,甚至在图像优化白平衡与多个光源。 auto(优先级)模式的叶子的颜色光源完好无损的额外的氛围,而Auto(默认)模式让相机自动白平衡调整。 总共12白平衡模式可用,包括三种自定义模式。 还可以调整白平衡的基础上,具体形象（？）,设置色温。 此外,每个可以调整白平衡模式的详细调整白平衡和创造性的过滤效果。

Full range of Color Modes
Color Modes can adjust color tones and contrast to best suit each photographic scene. The range of color modes includes Cinema, which reduces saturation and emphasizes shadows for a film-like effect; and Sunset Red, which emphasizes red for more impressive sunset shots. Color Modes make artistic expression easier than ever.
全系列的颜色模式
颜色模式可以调整色调和对比最适合每一个摄影的场景。 颜色模式的范围包括电影,它可以降低饱和度,强调为片状阴影效果;日落红色,强调红日落更令人印象深刻的镜头。 颜色模式使艺术表现比以往任何时候都更容易。

Monochrome options
The Filtering Effect allows contrast to be changed as if the images had been taken using a color filter for black and white photography. The Toning Effect allows warm, cold, sepia, and other color tones to be added to monochrome photos to emphasize the subject in creative ways. SIGMA Photo Pro makes possible optimal monochrome processing of RAW data without any color processing, producing high-resolution monochrome images with exceptional dynamic range and outstanding reproduction of the tones of highlights and shadows.
单色的选项
过滤效果允许对比改变图像仿佛被使用黑白摄影的滤色器。 塑身效果让温暖、寒冷、棕色等色调添加到单色照片以创造性的方式来强调主题。 SPP可以优化单色处理原始数据没有任何颜色的处理,生产高分辨率单色图像异常动态范围和杰出的音调的繁殖(噪点控制?)高光和阴影。

没有样片就是耍流氓

这个是DPQ也有的功能呢，机内可对RAW进行调整，输出jpg文件。dpm的固件要是能有这个就好了，可惜三木早就表明不再对M系有固件的升级。

这次说机内解RAW解x3。期待中。

我自觉SPP很好用啊。出片也很好。

说的好是有意愿努力去做好，期待结论要看实战出片的画质是否延续了真X3的色彩精髓 本帖最后由 虹桥梧桐 于 2016-2-25 11:57 编辑

怎么说呢，原来的技术导致色彩难以把控，直出是几乎等于不可用。现在的Q底能以较准确的白平衡出jpg，可以作为合格的消费相机了。暗部的问题，还待量产机出来检验才有定论。

为什么不能通过改进原来的技术提高像素？数据量太大？

暗部红绿色斑改善？不是说暗部彩噪更明显吗？
本帖由安卓客户端发布

一是像素提高了，二是高感进步了，三是暗部红绿色斑改善了（这个没看出来），四是电池变大了。最主要的原因还是像素提高，其实也没提高多少，但是大肆宣传插值后的3900万，其实m也有个双倍输出选项，但那时并没有宣传插值后相当于多少像素。主流消费者还是认像素，加入像素大战也是没办法的事。

那为啥要换这个呢？这不是倒退吗！成本低？
