I'm still a little irked I had to buy a Canon spare 5Dmk2 battery for $90 because they were no 3rd parties available yet. I guess at the time I was lucky to get the Canon version.


I bought a spare from Duracell Direct for my 40D once it seemed fine except it didn't come with a cover. It probably doesn't lastquiteas long as the Canon but for what I paid, I don't care.
