The fix is in: just-shipped Canon 5D III examined

Canon's EOS 5D Mark III digital SLR. Click for our Canon 5D Mark III preview!We got our first “new” Canon EOS 5D Mark 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.
