Canon 50D live view button
Just wanted to ask fellow Canon 50D users or anyone who knows whether you can turn on Liveview through the menu in the camera instead of by pressing the Liveview button on the upper left corner? Reason I'm asking is because I am planning to purchase a used Canon 50D and use it for underwater video with Magic Lantern. I currently have a Sea & Sea MX-40D housing and have used it with a Canon 40D camera for years, however, the 40D does not support video. I have also been told the 50D can fit in the Sea & Sea housing, however, there's no dial/switch on the housing to activate live view. Everything else would work fine by loading Magic Lantern, but I have no idea how I'd be able to activate Liveview while underwater?
Any ideas would greatly be appreciated.
