300d cool hack:
Got a 300D digital camera ? Want to force continuous AI Servo AF, outside of the ‘Sports’ mode? Of course you do – ‘Sports’ is a full-automatic setting, and doesn’t allow you to take RAW images. The solutions is to stick a 2.5mm mono audio jack (costs about 15 pence) into the camera ‘s remote-control socket, and this forces AI Servo AF in all manual modes. You can still change aperture in Av mode or shutter-time in Tv mode, but can’t shift the ISO rating up and down on-the-fly. (Tip courtesy of TonCee)
