DESCRIPTION

The new Canon EOS 20Da seems to be almost identical to the Canon 20D, accept for features like 'Live View' mode which enables the user to manual control the focus by using the LCD display. This is very handy when using the Canon 20Da for astrophotography. The subject can be viewed enlarged on the LCD display (5x or 10x magnification). Furthermore a special filter that normally is used to block infrared information is removed. The Canon EOS 20Da is equipped with a more transmissive mirror which makes the new Canon 20Da 2.5x times more transmissive compared to the Canon EOS 20D.
