No, I won't, because I won't have as high expectations for it. With all the brouhaha about how much better the DR will be with eeny, teeny pixels, I'm not seeing more than a marginal improvement, in the real world, not the lab, in DR from this camera over what my 5D (old model) produces. My camera would have blown the c* p out of those highlights, and so does this one.
Where's that DR improvement you've been trumpeting, bobn2?

You have some very strange ideas about what DR is. DR is NOT highlight headroom. It is headroom plus footroom. To not blow out highlights, without a camera with special compromises like the Fuji S series, you have to use negative exposure compensation. You do that with the 5D3, you risk banding much more, and the noise floor is over three stops closer than the D800.

You can not meter for ISO 100, at ISO 100, and expect to have much highlight headroom with any Canon or Nikon.

I know what DR is, it's both ends of the scale, not just the top or the bottom. But, I expect that, if you're metering for the mid, your gonna get both blocked shadows and blown highlights, if you meter for the shatdows, your going to get blown highlights worse than if you metered for the midrange. I"m looking at this, it looks like he metered for the shadows, indeed, but I'm seeing more blown highlights than I'd expect, that's all.
