I wish I had a second body to compare to...but during the last few weddings, I found the 85mm lacking in 1. low light tracking (where it had previously done pretty well) and 2. it couldn't focus accurately, no matter how many tries it had, on a bride's face at about 15-20 feet distance with the sky behind her. You would think it would lock nicely onto that darker object surrounded by white and blue, but it pretty much gave me inaccurate focus lock every time (like 8-10 tries). I was disappointed, although it does go along with the associated accuracy issues I've seen with distant subjects and 85mm on the D800.
I didn't take the new replacement 35mm out for yesterday's wedding, but I used it for getting ready for the previous wedding and it gave generally accurate center point AF-S shots with generally inaccurate (backfocused often) AF-C shots with any point, especially outer points. Field curvature? Focus shift? Not sure, was around f/1.6-f/2.
Anyway...if I gave up the Nikon I would miss the autoISO for daylight and mixed shadows, and I would miss the dynamic range recovery of shadows...but if it keeps disappointing me (I posted my focus issues on the Nikon forum to see if there are workarounds) then I will probably dump it in favor of a 5d3...which I didn't really think I'd ever do.
