Hi,

I don't really think the diffraction limit is a problem. Stop down below f/16 and blame yourself. The loss between optimal aperture and f/16 can certainly be measured but I don't really think it matters that much. On the other hand I would say that f/64 is an extremely bad idea in the era of imagers with 6 micron pixel pitch.

The MFDB/view camera guys have a point. Focusing with a good loupe on the ground glass takes much of the guess work out of depth of field,if the MFDB has "live view" it is even better.

But that's even harder to manage with MFDBs.

The tighter is the pixel pitch the more difficult it becomes. With weak AA filter on D3X diffraction effects are visible past f/5.6.

Hello Jost,

Have you had the opportunity to re-shoot some of this with a prime lens on the d3x?

Thanks.

Cheers,
Bernard

Hi Bernard

Yes I have!
I did a whole comparison with the Zeiss ZF 2/100mm, more carefully watching focus (with Live view!), diffraction limits and using MLU of course again.
I also processed the files with various settings. NX still remains my preferred method for the NEF files.

My 24-70mm was perfect on the D3, but it has to be checked with the D3x by Nikon: Tolerances are getting even smaller now due to the diminished pixel size....
The D3x definitely does have a significant advantage in resolution over the D3, but only visible with the best lenses (as expected).
I have therefore already traded in my D3.
I also just finished my first professional job with the D3x with great success:
Winter advertising images for a local cable car company (in our swiss mountains). The D3x worked absolutely flawlessly and delivered!

BUT the gap between the 35mm sensor(s) and my P45+ remains big.
So whenever I can, I prefer to shoot "old style" with my ALPA SWA on the tripod, with focussing on the ground glass with a loupe: The precision can't be beaten.

I habe also published a comparison between the D3 and the D3x at 1600ISO using the ZF 100mm, but without another P45+ image to compare with:
http://forums.dpreview.com/forums/read.asp...essage=30418008

Because of all kind of images and comparisions on the net with the D3x involved, I'd rather not publish any more samples.

Thanks for your interest.

It's the capital of Switzerland: Bern, with the governmenthouse in the back (left).
