Look at the great test recently posted by Trumpet Guy. Check out any of the pairings at f/5.6 or greater, and zoom-in on the roof tops. The Nikon has significantly better 3D at far distances. Strange, but true.

Cableaddict is referring to this set of test images on my pbase site:

Be sure to view the original (100%) files.

I guess I don\'t notice much difference in 3D look, but I haven\'t spent much
time looking for it either.

The Zeiss look is something I like, but I must admit that for an all-around performer,
the Nikon looks best across apertures. There is a certain \"zing\" to the images
of the CZ at f/8 and f/11 that I like. The lenses are very comparable for landscape
work, in my book. I would choose the Nikon, though, if any wide aperture work is
intended. The Zeiss is no match at f/2.8

My apologies for not matching the exposures from the two lenses more precisely.

Regards,
Tim

P.S. In my test images it looks like I focused a tiny bit closer on the Nikon shots
than on the CZ shots. The adapter I was using on the Nikon at that time was
too thin, and allowed focusing way beyond infinity. Thus, I was tweaking it back
and taking images and trying to find the sweet spot for infinity focus.

I now have a Novoflex adapter (expensive, German adapter) that is perfect at
infinity focus on my 5D.
