Overview

Description by Canon:

The EOS 20Da is the first Canon digital SLR that has been tailored to the requirements of the Astro-photographer while delivering the speed, precision and flexibility synonymous with the EOS 20D

Quality
The EOS 20Da is no ordinary camera; maintaining the key features from the EOS 20D, the EOS 20Da has been tailored to the specific requirements of the Astro-photographer.

Astrophotography
The diffuse nebulae is popular among Astro-photographers for its distinct reddish colour caused by the excitation of hydrogen. However, with the infrared (IR) blocking filter in front of the imaging sensor on standard digital SLR's, the reddish colour is eliminated. The 20Da IR blocking filter has been modified to allow more IR light through to the sensor, recording the reddish colour.

Technology
The EOS 20Da delivers outstanding images with 8.2 Megapixel resolution. The DIGIC II architecture drives high speed continuous shooting with a large maximum burst and quick start-up times. The 20Da has a new feature enabling easier manual focusing with a live, magnified image on the LCD monitor.

Full control
An extreme high (3200 ISO) setting extends the camera's wide 100-1600 ISO speed range. Both sRGB and Adobe RGB colour spaces are supported.
