This is a not a review of the Sony CLM-V55 but a simple test of what Magic Lantern can do with the HDMI output.

The problem is the blink of the 5D when you start recording. Magic Lantern can adjust this problem by setting the output fixed at 480p.

Magic Lantern for Canon 5D is still in beta and you must donate to test it... but it's really really helpful also for other cool stuff!! So DONATE and try it!!! :)
