Re: 没有做不到的：瑞士产的超人版DLSR

这款巨相机可以生产出长六厘米、宽十七厘米的宽屏照片（7500 x 21250像素）。ISO范围是五百至一万，而快门速度最快可以达到两万分之一秒。正常情况下，拍摄一张照片需要使用将近1GB的储存空间。因此，它并没有使用存储卡，而是使用一台MacMini作为存储设备，输出速度为三百兆每秒。这台相机的体重是2.8公斤，这还不包括2.6公斤的移动存储设备。体重惊人，价格也惊人。“移动版”的售价达到三万六千美元，而“工作室版”则是三万三千美元。

High Speed & Sensitivity

World record: with a 1/20'000 sec. exposure our new Roundshot D3 camera creates a full 360° rotation digital panorama in only 2 seconds at full resolution! This is possible with our new Seitz D3 scan back. Thanks to a very high read-out speed of 300 MB per second it is 100x faster than any existing scan back. This means: high quality images full of speed, motion and life! Compared to previous surface sensors, the sensitivity of the Seitz D3 sensor is significantly higher. Or compared to conventional scanning cameras, the sensitivity is increased by factor 100. This results in a very broad ISO/ASA range (equivalent) of 500 to 10'000, which makes this camera the perfect instrument for virtually all light situations. Our new stage selection technology allows to control sensitivity by selecting smaller or larger areas of the sensor. This means: additional sensitivity without any additional noise!

Substantial Resolution

With this new technology a new exciting chapter has begun: high definition 360° digital photography. Combined with the vertical resolution of 7,500 pixels an 80mm medium format lens creates, for example, a total image resolution of 470 million pixels. Or go even further by shifting the scan back by a total of 50mm and achieve a vertical resolution of 13,500 pixels (110mm) by distorsion-free stitching. This substantial resolution combined with impressive speed and sensitivity makes it possible - for the first time - to create lively digital images that are a pleasure for the eye of the professional. No limits for high definition photography!

Very High Image Quality

We have achieved a true technological breakthrough not only in speed and resolution but also because in its impressive image quality. As our scanning camera uses only the middle section of the lens, it allows maximum edge-to-edge sharpness without vignetting. The image has a 48-bit colour depth and a high dynamic range. When shooting directly into the sun, the sensor’s anti-blooming feature reduces glare and allows a clean passage between highlights and lowlights. The image is further enhanced by advanced optimisation algorithms developed by Seitz for ultimate image quality. Or work directly on the raw image and apply your own raw conversion preferences.

Leading Edge Digital Technology

The Digital 3 scan back sensor has been designed and developed exclusively for Seitz by DALSA Corporation. In this multi-year project specialists around the world have brought together the best capabilities in digital technology, computer science, image optimisation and knowledge of photography applications to build a camera system that goes beyond the imaginable.

A Pleasure To Work With

The Roundshot D3 is simply a pleasure to work with. Operating the camera is easy: a touch screen can be attached to the camera body or removed for wireless control with all camera functions displayed via simple graphical icons. The 640x480 pixel colour screen is the biggest camera screen today and allows perfect preview, editing, zooming and image control.

Latest Computer Technology

A 360° digital panorama at 48-bit uncompressed taken with a 80mm lens represents about 2.7 GB. To process and store such large amounts of data we have created a state-of-the-art computer system. Data is transferred by gigabit ethernet from the sensor to the storage device. The portable storage device is itself a computer with most advanced characteristics in processing, disk space and memory features. Additionally, the camera and handheld control unit takes advantage of the latest IP network technology, making it possible to connect the camera in a network and control it remotely.

Fully Mobile & Open System

We designed this camera to meet the expectations of those photographers who like to take their equipment on exploratory adventures. All components are fully modular - the portable storage device and the handheld device can be adapted to your specific needs. The camera can also be used in the studio, running the software from a computer (Mac, PC, Linux) via ethernet connection. For best image results we recommend using the advanced medium format Schneider lenses on an interchangeable lens mount. Of course all other medium format lens brands can be attached to the Roundshot D3 camera as well, for example: Rodenstock, Hasselblad, Pentax 67. All lens types and brands can be interchanged without any restrictions, provided that the aperture can be set directly on the lens.

A Rewarding Investment

Just like a traditional digital back the Seitz D3 scan back cassette can be removed from the Roundshot D3 camera body and fitted to other cameras, e.g., our new Seitz 6x17 panorama camera and, in the future, other large or medium format cameras. The possibility to use the scan back in a variety of different cameras makes the system truly versatile - to the benefit of the photographer.

Uncompromising Precision

With increasing image resolution the engineering precision of the camera hardware becomes very important. All our cameras are made from solid blocks of aluminium as used in space technology with most modern CNC machinery. Our machining tolerances are at the decisive 1/100 mm. Uncompromising precision and perfectly adjusted lenses are our guarantee for excellent results. Every Roundshot D3 camera is hand-made in Switzerland and is unique.
