The EOS 20D is not only smaller and lighter than its predecessor, the inner values have been improved. This is literally "short" after turning clear: in just 0.2 seconds, the EOS 20D for shooting. The shutter lag of 65 milliseconds is at the professional level. Responsible for the quick start is first and foremost, the new DIGIC II processor, which is also used in the professional EOS 1D Mark II is used. The extended buffer size of the second generation DIGIC processor makes a series of image speed of 23 frame burst at up to 5 frames per second, surpassing the EOS 10D, nearly double. JPEG and RAW files can be recorded simultaneously, especially convenient feature is now the choice, what options JPEG and RAW should be recorded.
The new 8.2-megapixel CMOS sensor built for the new EOS 20D. In addition to its high resolution, the sensor provides a sensitivity range from ISO 100-1600, can be pushed in the "H" setting, even at ISO 3200. It is true that the new CMOS sensor the same dimensions as its predecessor, is due to around 30 percent higher resolution, the size of the individual photodiodes, however small. Improved high performance microlenses over each photodiode help despite smaller diode area is an excellent signal to noise ratio to achieve. For the new microlenses to increase the efficiency of the incident light and thus increase the ISO performance and image quality. In addition, a new optimized the noise reduction circuit: It amplifies the signal from the photodiode and thereby effectively suppressing unwanted effects, such as white noise and pixel raster effects. A three-layer optical low pass filter also reduces color distortion. Particularly convenient can now adjust the white point to individual preferences and style. Based on the above illuminant (daylight, tungsten, etc.) set white point, the photographer can adjust this white point in an extra menu with the jog dial in the direction of red-yellow-green and blue. A bracketing function calculated on request at the reception even more color options.
Brings super-fast autofocus with nine measuring points decisive advantages in practical applications, above all, the new autofocus system. The 9 lozenge arranged around the center AF points cover a larger image area than the AF system of the EOS 10D, but above all, the autofocus has become significantly faster. For the implementation of lenses with an aperture of 1:2.8 or higher, the central focus point can alternatively be selected as a cross-shaped AF sensor area. The choice of sensor points is an alternative to the large EOS-dial or the new multi-function selector switch on the back of the camera.
For even better results when using the internal flash and external Canon Speedlite flashes, the EOS 20D with E-TTL II distance-equipped flash metering. E-TTL II involves the calculation of lightning performance of additional factors, such as the distance setting of the lens in the ambient light measurement and has a detection of reflective objects. In this way, the quality is improved due to flash, especially in critical situations. The EOS 20D is compatible with all EX-series Speedlite flash range, including the new Canon Speedlite 580EX. The reflector of the new flagship model of the Speedlite series goes to the debate on the EOS 20D automatically in the position, in conjunction with the sensor size of the EOS 20D, the optimum illumination of the image circle ensured. For an even more stable color rendering submitted at the Speedlite 580 EX flash color temperature information to the camera. This ensures, even with different flash services with a common color. The integrated flash of the EOS 20D works out higher than the EOS 10D and so reduces the risk of red "flashing eyes".
Sophisticated black and features a reason for many amateur photographers and professionals who continue to work with analogue photo technology that had previously been the many creative possibilities of black and white photography. Here, the EOS 20D makes a decisive step forward. For it is the first Canon digital SLR body camera features a versatile monochrome mode with the black and white shots with similar settings as in analog photography are possible. Particularly noteworthy are taking filter simulations for the filter colors yellow, orange, red and green. These can be digitally inserted into nearly the same way as do advanced black & white with black and white film photographers. To create a Rotfilterung example, the most dramatic effects of clouds, the green filter provides for black and white portraits for a more pleasing skin tone reproduction. A specialty of analog black and white processing in the darkroom are Tonungsverfahren. These effects are available to the EOS 20D photographer in the camera is now available and that - without any chemicals - for shades in the colors of sepia, blue, purple and green. The black and white image files are saved as an RGB file, so that the photographer standing in a further processing on the PC open to all options.
The EOS 20D features the first Canon digital SLR body camera with fast USB 2.0 Hi-Speed interface. USB 2.0 Hi-Speed is approximately 40 times faster than USB 1.1. So, first, accelerating the transfer of data is from the CF card to PC or Mac with the download, on the other hand, the EOS 20D now also be easily used in a photo studio environment in conjunction with a PC, eg in portrait studios. The photos here are directly transferred to the host to the PC directly stored on the hard drive. Requirement for fast data transfer is that the USB port of the computer supports the USB 2.0 standard, otherwise the transfer takes place only at USB 1.1 speed. The EOS 20D also supported via USB Direct Print function: in conjunction with photo printers that can support the PictBridge standard vendor will geprintet the pictures in the camera without having to use a computer. For the slide show via a video projector or TV, the camera has a video-out port. The EOS 20D stores the files on CompactFlash cards Type I and Type II cards, including Microdrives, and memory cards with capacities of over 2 gigabytes are used.
The new image processing software Digital Photo Professional v1.1 enables rapid processing of lossless RAW files. Processing with Digital Photo Professional is up to about 6 times faster than with the previously supplied File Viewer Utility. The new RAW Software permits real-time display and immediate adjustments to images and also includes comprehensive editing features, including White Balance, and lateral chromatic aberration, Digital Photo Professional application sRGB, Adobe RGB and Wide Gamut RGB color spaces and ICC support-compatible. RAW files to TIFF or JPEG formats to be converted, may, after the transition, a camera specific ICC profile are appended. In this way, the color rendering in software applications that support ICC profiles, optimized. Batch processing (batch function) significantly increases productivity because it allows the automatic through several files with the same conversion settings. The Canon EOS Solution Disk 8.0 includes addition, the Digital Photo Professional software programs EOS Viewer Utility 1.1, EOS Capture v1.1 and PhotoStitch 3.1. Adobe Photoshop Elements 2.0 is a powerful image editing software.
