A few weeks back I decided try the Magic Lantern hack. It was scary at first, because you're hacking into your camera's internal programs with the risk of making your $899 (now $699) camera into a paperweight. Well, it was actually easy to install and the more I think of it, you really can't brick your camera because the hack is programmed into your SD card. Install Magic Lantern on 1 card and if you want to revert, just disable/delete (there's a proper way to) the Magic Lantern files. Or, insert a SD card without the program and the camera is back to normal.
Updated builds keep coming out, and I have to mention the March 31 build would not work for me when trying to monitor audio through my Rode Videomic. I found posts from Dave Dugdale and Sven Rose that helped, and after testing out all the builds from March 10-31, I concluded the 29th was the last one with full monitoring capability (at least for me).
There are many ways to set up your camera to monitor audio, some expensive some cheap. What I'm using is the mini-USB to composite cable that came with the camera, a female RCA to 3.5mm cable, female to female 3.5mm, and some cheap headphones. I've seen other posts that mention using a mini amplifier for your headphone, but I'm fine with my setup.
Aside from audio monitoring, here are the other NEW capabilities I'm loving with the Magic Lantern hack:
- AGC disable
- Timelapse without needing an external intervalometer
- Timelapse without the shutter going on and off, saving actuations
- Auto restart after 15 minute record limit (there's a 1 second gap between recordings)
- Zebras for exposure
- Auto focus during video recording (works but kinda slow)
- Change the bitrate settings
The best thing about it is that it's FREE. I suggest you check it out and read all the documentation and watch the videos BEFORE you try to install it.
Here's a timelapse test using the built-in feature in Magic Lantern. No need for an intervalometer now. Also, these pictures were shot with the mirror up, thus saving actuations on your camera.
