We got our first “new” Canon 5D Mk III cameras today, the ones with the light leak fixed. You know me, I thought perhaps it would be a good idea to take one apart and see what was different. I had photos from the ‘prefixed’ 5D IIIs from a previous post, so comparison would be easy.
Let me say it here first: I knew this was going to be the fix since the first time I took one apart: Canon has this very cool black tape they used to cover circuit boards (I’m assuming either water resistance or electrical shielding or both) and I figured they’d just slap another piece over (or under, depending on your point of view) the top LCD light. Which is exactly what they did. Yes, I’m making fun, but it’s a perfectly good solution and it works flawlessly.
And because I know you have enquiring minds: I did power the camera up with the shell off in a dark room. There is no more leak.
Addendum: for those who notice there is a black plastic piece over the shutter button that was removed in the first photo, but not this one.

Sometimes I forget that other people don’t spend most of their days looking in cameras and lenses. Some people seem to think tape is bad or cheap fix. It’s not. Actually, I can’t think of any SLR camera that doesn’t have a bunch of tape inside. Nor can I remember any high quality zoom lens that doesn’t have tape inside (some of the cheaper consumer grade lenses don’t). This stuff lasts for the life of the camera and then some. Trust me, I’ve taken some water soaked equipment apart where the only thing still working was the tape.
In a previous post, I praised the broad sheets of the same tape used to cover all of the circuit boards: it obviously provides added protection. This solution seems silly, but it’s logical and effective.
