Fast moving subjects are best used in the Tv mode, combined with the EOS 50's AI Servo AF, such as motorcycle races, like those shown below - which was the final round of the 1999 FIM Asia Road Racing Championship, using the EF 70-200mm f/2.8L USM with Extender EF 2x. A 250cc rider in action First-sequence shot Second-sequence shot Third-sequence shot For the above sequence shots, the effective focusing was set to the camera's right AF point and this made it possible to track the leading 250cc rider (No: 45) as he moved out of the chicane. In addition, the EOS 50, together with the EOS 50E, is the lowest category model in the EOS line-up that incorporates Canon's built-in Custom Functions where the user can custom-tailor any of the 11 settings (10 for EOS 50) to his/her liking. I used CF-4-1 to switch the EOS 50's AF start button with the AE Lock button instead. Text and photos by Philip Chong.
