Canon 20D PDF User Manual

Did you lose or misplace the instruction manual that came with your Canon EOS 20D? It happens all too easily, but fortunately Canon makes a soft copy available that you can browse through online, print out, or download (see the pdf file below). It is certainly good practice to carefully familiarize oneself with the many different functionalities and options that the 20D offers, and the official user manual is without doubt an authoritative and comprehensive source of respective information.

That said, the instruction booklet can be a dry read, so that a dedicated camera guide book from a professional photographer that illustrates the camera's core functions in a real life photography context can be a very helpful complement. Yes, getting one of these camera guides (see here at amazon) would involve an additional expense, but if that book helps to exploit the camera's potential to the full, the (small) additional investment may well be worth it.

Also, you might want to check out the video tutorial on the Canon EOS 20D below.

In any case, the 20D is an advanced imaging tool, whose many features merit serious attention. This DSLR (Digital Single Lens Reflex) camera was officially introduced on August 19th, 2004, which means that, as of today, the camera is 6670 days old (young?). The camera has meanwhile been discontinued and was succeeded by the Canon 30D as a replacement in the same line of cameras.
