EOS 20D - the digital mirror chamber, which unconditional advantages: anew developed CMOS-gauge of the second generation of format APS-C about 8.2 million pixels, speed of continuous shooting of 5 staff a second, 9-dot autofocussing and the system flashes Canon ETTL II connected to distance.
In chamber EOS 20D, known model EOS 10D, same processor DIGIC II, as in professional chamber Canon EOS-1D Mark II is established. The processor of second generation DIGIC raises and without that the best in this class parameters: accuracy , speed of data processing and time of inclusion of the chamber. The strong case from a magnesian alloy emphasizes professional shape of chamber EOS 20D.
Basic elements of popular model EOS 10D have been designed anew for expansion of opportunities of shooting and improvement of quality of the image. The processor of second generation DIGIC II in a combination to the increased size of the buffer provides shooting by series up to 23 staff at speed of 5 staff in a second - that almost twice exceeds opportunities EOS 10D and ideally approaches for shooting dynamical stages and natural objects. Files JPEG and RAW can be written down simultaneously without loss of quality.
And without that a wide range of sensitivity of chamber ISO 100-1600 even more widely due to it becomes unprecedented to high value - ISO 3200. Application of touch elements of the smaller area with the improved parity signal / noise and the raised equivalent sensitivity has allowed to raise density of pixels in comparison with EOS 10D at the same size of a matrix. The high quality microlenses located before each touch element, raise the light stream falling on a sensor control, improve parameters of the chamber at high sensitivity and raise quality of the image. The microcircuit located directly on a sensor control, reduces noise level and strengthens a signal at slow reading, eliminating noise from contact conductors and casual noise, and the 3-layer optical filter of the bottom frequencies located before a sensor control, reduces effect of false colors.
The advanced gauge and algorithm of autofocussing, and also increase in number of points of autofocussing on the wide area with 7 up to 9 raise speed and accuracy of autofocussing that is especially appreciable at shooting noncentral objects. Points of autofocussing not only block wider part of the staff, but are located in such a manner that the opportunity of fast and sharp focussing opens at construction of a composition on classical proportions - « a rule of one third » or « gold section ». The central point of focussing works as the crossed gauge at use of objectives with the aperture f/2.8 or is wider.
