It had to happen:
After small hacks like FECSet (set Flash Exposure Compensation) and the 2.5mm jack trick (forces continuous AI Servo AF), now someone’s released a full firmware hack for my Canon 300D camera . This one apparently enables some of the advanced features of the 10D. Read about it and find it here, but try it at your own risk. The zip I downloaded didn’t come with a readme.txt file. Rumours suggest the firmware was dropped by either…. a) Canon Russia, b) Nikon, c) black helicopters from a secret undersea base off Weston-super-Mare.
