550D

Magic Lantern has come a LONG way in the last few months. It now has almost all the same features as CHDK for photography (if not all), as well as tons of video and audio features not present in CHDK. Features like motion detection, focus tracking and racking, crop overlays, audio monitoring, lcd, face detect and audio-based remote triggering, lightning catching, ldr and hdr intervalometers, custom-set on-off intervals for timelapse, power management, bitrate control, auto-restart for video, exposure helpers (zebras, histograms, false color, waveforms), in-camera help screens for all functions, NEED I GO ON????
