I love 5D2 skin in C1 and in DPP. I shoot a Macbeth chart, balance off of that. Strong light gets a nice file. The only camera I like better, at least out of the box, is the M8.
The 5D2 is remarkable. I have lots of cameras, ds3, two 5D2s, two backs, RZs, Sinar 4x5 to 8x10, an Arca F line, too many Leica film cameras, an M8, and M9. I don't shoot stills much these days, but when I do, and it has to be digital, I toss two 5D2s, a 35, two 50's, two 85s and a 135 into a bag, and get on with it. No BS, I just get to making photographs and forget all the science, magicical thinking, consumer psychology and angst involved with cameras and just make photographs that inspire my client, and hopefully me as well. While the 5d2s thmselves don't produce rapture and trancendence, it just works, all of the time, whenever asked, and you can use it for B roll as well. Oh yeah, thy are $2200 bucks, slightly more than the Leica 28 ASPH. All the talk about pattern noise and false ISO, read noise, blah blah blah is fine, but look at the photos coming from Libya, Afghanistan, Yemen. Beautiful images, inspiring. Mainly shot with 5D2s.
Carry on, I'm done.
