Reasons for modifying original cameras firmware

6.3 megapixel EOS 300D/Digital Rebel is based on the same CMOS sensor and DIGIC microprocessor as EOS 10D, more expensive digital SLR from Canon. Similarities between those two models suggested that most likely EOS 300D/Digital Rebel uses the same code base as EOS 10D with some functionality disabled at software (firmware) level. After close firmware analysis, by changing only two bytes, Custom Functions menu, identical with EOS 10D, but disabled on EOS 300D/Digital Rebel, was successfully revealed. Since EOS 300D/Digital Rebels firmware lack of certain subroutines, not all functions available in this menu are working on EOS 300D/Digital Rebel. Nevertheless, as for today, modified firmware provides EOS 300D/Digital Rebel owners with following additional functionality:

  • Enter Flash Exposure Compensation using SET button
  • SET button function when shooting
  • Shutter release w/o CF card
  • Flash sync speed in Av mode
  • RAW+JPEG rec. Sets the quality of embedded JPEG
  • Mirror Lock up
  • Selects the autofocus mode: AIfocusAF, ONEShot
  • ISO 3200
