Even with that, it has the 7D meter... i haven't heard anyone on any blog ever complain about the 7D meter...It works well right! This is a classical answer when people question about why canon don't offer the latest stuff in 5D.
It's true the meter is from 7d, and it's from T3 as well.
It's nothing to do whether it works well or not! It's all about our hard earn money, when a cheaper model put the latest technology from their top model, Canon just put something essential from their cheapest model for next three years.
By doing this, they can cripple another feature which is AF point-linked spot metering. That's why they didn't put this "zero compain" metering system in 1d4.
I am not complaining anything and I will buy 5d3, just want to say some facts.
