Disclaimer: this was for purposes of my own curiosity. I don't consider it scientific enough to prove anything at all. I am aware of the non-prefect technical aspects of the experiment and I do know that this is comparing apples to oranges but
a) I like fruit
b) Sometimes I want to know if the apple will be more satisfying than the orange
First off, developed in LR4. No howls of protest from either side, I will be doing C1 later.
All shots on a Gitzo three, Cube, MUP and remote release.
The D800 using a Leica 50 Cron at F8, ISO 50 and 1.6 seconds
The IQ180 on Phase DF with Phase 80MM standard lens @ ISO 50, F8 and 1.6 seconds
The Phase file came out a tiny touch lighter, but showed clipping warnings in the blacks and a touch in the whites. Maybe the lenses have different T stops or maybe the nominal versus actual ISOs differ. The Nikon file had fewer warnings at both ends (none in the whites other than in the bright window ledge on right, which is not shown in the Phase file because of the slightly different aspect ratio and FOV).
This is intended to show nothing about resolution: it can't because the focal lengths of the lenses are different so the DOF varies widely between the two. I chose these differing focal lengths because the both 'normalise' to about the same FOV - they are both 'standard'.
I did the test purely to test my suspicion that I was getting cleaner shadow detail from the Nikon files than I had ever seen elsewhere, at my normalised printing resolutions of 200DPI.
That is a long-edge print from an un-cropped Nikon file of a touch over 36 inches, which at this aspect ratio is 24" on the width - the largest print that almost anyone can make at home or even in their professional studios without having to outsource.
The most relevant crops are prepared as follows: the Nikon files are reduced to 1:2 and the Phase files to 1:3 so that they both approximate to a 36 inch print on the long side for the Nikon and 34 inches for the Phase.
These downresing ratios clearly favour the Phase files, but are a good representation of how I print from both cameras.
Right, just been called to lunch. Images coming soon thereafter....
