2. OVERVIEW
2.1 EOS 20D body
While retaining the best features of the EOS 10D, the EOS 20D is a high-end,
digital AF SLR for advanced users. New technologies have boosted the basic
performance and user suggestions have also been incorporated.
Table 1 compares the EOS 20D and EOS 10D. (Shaded EOS 20D specifications
are superior to EOS 10D's.)
The EOS 20D's improvements over the EOS 10D are outlined below.
