I am very wrong or are we all comparing two very different cameras with different purposes? As I see from what I've been reading, the D800 is more a studio/landscape camera, and the 5Dm3 more an all-around camera, maybe what wedding photographers want. People seem to want a 30+ MP with a ton of DR and 10 FPS... No can do. Very different cameras, very different uses, or am I wrong?
I don't understand the US$ 500 difference, though.
It really seems that a high MP studio work/landscape camera missing in Canon's lineup, but it looks like it's on its way (or not?).
In the beginning I didn't like this "mark x" thing, but now I like it and see advantages. What if:
- 1Dm_ for insanely high FPS and ISO (sports)
- 3Dm_ (or some new series) for high MP studio/landscape
- 5Dm_ for all-around FF (weddings)
- 7Dm_ for best crop sensor
- xxD for little better than entry-level
- xxxD for entry-level
Makes it easier for everyone. If I'm a sports shooter, then I know Canon's got 1Dm_ line that suits my needs; if I'm into landscape, the 3D series is my stuff, and so on.
Anyway, I think 5Dm3 and D800 are not comparable, and the 5Dm3 will be a very good camera for what it's intended to (although a tad expensive).
