Oh, what I feared, no real DR improvement.
If further tests confirm this, I'm not going to buy the 5D Mark III, especially not at the extreme price point Canon has chosen here in Germany.
DR improvement was crucial for me. I'm really disappointed if this turns out to be true.
I had a chance to touch the new 5D & the D800.
I have to slightly adjust my statement above, I still have an issue with the pricepoint in Germany,
There were some things which I liked a lot... For me haptics and grip are important too and
the 5D Mark iii just melted into my hand.
The touch dial is really great and the control with the, let me call it "JOYstick", was very intuitive.
I just don't like were Nikon placed the ISO button.
I like to fiddle around with settings
and Canon is just faster for my taste.
There are other tiny, little, maybe for you unimportant, things like, well call me stupid, but for example I like the orange backlit at dim light compared to the greenish one from the Nikon Topdisplay.
My hand and feel is not made for the Nikon design, thats what I noticed again!
I can and will compensate some DR in post processing.
I like the HDR blending, autoalign(!) of the 3 photos, for me, who frequently quickly does handheld shoots, its a new step forward.
I like the 2 shoots comparison on the large screen.
When I touched the 5D, I was reminded of one of the reasons I went with Canon, its the haptics, grip & control.
For me making photos is not a job, its a joy.
Still my budget is tight, so I'll have to wait a bit. But I think everybody who is currently concerned about what to do,
Try To get hold of the cam and really focus on the things you really need and prefer. Then forget about all the forums.
In the end I noticed its me taking the photo, not the cam,
if I have fun then I'm happy.
Just my 2 cents I wanted to share
