Quote from the owner of this site, Michael Reichmann, (September 2012).
Medium format backs and cameras used to be where one went for ultimate image quality, especially for high pixel count and wide dynamic range. But the 36 Megapixel Nikon D800 and D800e have thrown that equation into a cocked hat, and now there are rumours of a 46 Megapixel Canon later this year or early next (these rumours are likely true).
The issue of DR has been an interesting one to follow.
Here, over some 3 years
[2009-02-04] prior to the above assertion
comes something sounding quite different, IMO:
Roman Johnson's OP: "Quick Question, Michael, about D3X and P65+ DR" ]
Since you have some experience with both.
I see Thom Hogan reporting about 10 stops of usable DR in the D3X files he has worked
with on his test machine. I see Phase One reporting 12.5 usable stops of DR with the P65+
camera you're testing....and of course the DXO numbers are what they are.
I know you're not an exhaustive tester like DXO or other sites, but in your normal use,
how would you describe the diffrences between the DR of the two cameras from a visual standpoint?
[MR replies : ]
| No, not in any objective way. Of all the metrics DR is the hardest to quantify.
| It's very difficult to test and varies depending on a number of variables
| which I am not comfortable in quantifying.
| I doubt that anyone could see a noticeable difference between the two though in real world shooting.
[ Yet a year later there came the infamous assertion of not only seeing
a noticeable difference, but seeing it at ~10 paces in small prints! ]
| At base ISO most top-end cameras now are displaying about 12 stops of DR.
