I wanted the 20D for it's renowned speed!! Since I mainly shot candids I needed a fast cam and was SO frustrated with the Sony! I missed lots of shots with that one, so bloody slow!!! And I also wanted to have bigger zoom options and so all this screamed SLR! Then I browsed like mad, reading tones of reviews and the cam that always came back first was the Canon 20D! So, after saving for 3 months, I got my dream cam! :D
