I got my 5D III from 1st patch and still running with original firmware - SOLID -
Do you ever upgrade firmware? I tend to keep current but not sure if it is worth the risk (camera gets locked up just at the wrong time).
Still using original firmware(ver: 1.0.7) and original "Light Leak" issue
Me too. My lens cap shots are just terrible. And EWP, I agree with the 1Dx's exposure vs. the 5D3. I confirmed it today. I would say, and I'm speculating, that this is designed such that at 0EV, there are no highlights blown, in evaluative mode. I don't know for sure though. The 1Dx has some added sophistication to its metering system.
