Wedding photographer here. Just purchased the 6D after years of using only the old 5D bodies for wedding photography. Pretty happy with my purchase, but been noticing the weirdest thing since I got it.
Taken it to a couple of weddings and noticed the it has a tendency to meter *way* dark on AV when there's any kind of bright back light. For example, while shooting some 'first look' photos in a grove of trees, the photos shot on AV (at a 0 exposure, no +1, -1, etc) were WAY too dark. Maybe about 90% of the photo was underexposed, while tiny little bits of bright light peaking through leaves and branches were properly exposed. It's like the 6D took that tiny bit of brightness in the frame and decided to expose for that, instead of the 90% that was all shade.
It was infuriating. I started shooting somewhere between +1 and +2 while in AV. I had one of my 5D bodies at my side as well. Didn't experience those issues at all.
Funny thing? I borrowed a 6D from CPS before making the purchase decision. I could be wrong, but I Don't remember this problem *at all*.
I've used the 6D I purchased at 3 weddings now, still the same issue. But no problem with the old 5D bodies.
Anyone else have a similar experience with their 6D?
