Re: Nikon d7000
Hier een test of indruk , zal toch wel een vet toestel worden denk ik, begin nu toch wel ongeduldig te worden.... van dpreview forum
Preliminary results - D7000, D700, D300
This will probably stir up some controversy, but here goes.
I spent the better part of today testing these 3 cameras. I was somewhat shocked, so I did it again. Same thing. Now we await the REAL scientific tests like dpreview and DXO. Using an ISO 12233 chart as well as a Macbeth Color Checker I came up with the following results. I used the same lens (Nikon 24-70) on all three cameras and adjusted the focal length for the same field of view (no easy task with the D7000 showing 100% in the viewfinder and my D700 only 96%). All shots were done in raw and converted using Nikon ViewNX 2.0.2. (I still am an Adobe Camera Raw fan, but I have to wait). The photos were compared with no sharpening and again with USM at .4 at 100% and 0.
My findings: The D7000 really needs to be compared carefully with the D700. It pretty much whipped my D300 in every IQ catagory.
1- The D7000 has better resolution then the D700 (expected) Considerably better (not expected).
2- The noise level of the D7000 at 3200 was equal to the D700 WHEN BOTH FILES WERE MADE THE SAME SIZE (either by upresing the D700 or down rezing the D7000 in PS CS5. Comparing the two totally different file sizes at 200% gave a 1 stop edge to the D700. But we DON'T print that way. We print a certain size. The same scene printed at 16 x 24 inches would display equal noise from these two different cameras at ISO 3200. Wow. This was a shocker.
3- Dynamic range is more difficult to measure. First you need two files that have identical levels and curves. This is very difficult to do. Based on my attempting to "stretch" the DR in PS CS5, I would say the D7000 might well have an edge here also. (totally unexpected) This awaits real tests.
