The AI and AIS lenses work fine on the D200. Most of the non-AI lenses can be converted to AI and they also work fine. Just be aware that the D200 requires a wider gap on the mount to be cut than the FE2, FM2 etc, because the camera prong cannot lift up like on the older bodies.
What exactly do you lose when mounting the A1-S lenses on the D200
apart from AF( BTw is the D200 screen OK for MF?)
Because the D200 uses and APS sensor, the field of view will be smaller or narrower, creating the impression that the lens has an effectively larger focal length. The viewfinder is good, but not what you might have been used to on an F3 or FM2. Add a magnifying eyepiece to your camera, and it should be slightly easier to focus. I also changed the viewfinder to a splitscreen, but mostly it does not make a big difference, except with long teles. The D200 has a nifty feature that allows you to dial in the focal length and maximum aperture of the MF lens. This means that the correct f-stop is shown in the viewfinder, and the exif data also show this information, making it useful for sorting etc.
What is the situation with the ziess lenses that were going to come
out in Nikon fit?
The benefit of AI/AIS compatibility lies with speciality lenses, i.e. lenses that are just not available in AF. They include PCs, wide and normal fast primes, flare resistant wides and some unusual zooms. Over and above that, the older MF lenses are cheap used, and some (not all) are better than their AF counterparts. They are also built well, and some may outlast their AF counterparts by a few lifetimes if well looked after.
The Zeiss lenses are for special purposes only, and come at a price that requires a very serious consideration of what you want to do with such a lens. The 100/2 macro is said to be 1600 USD. On the other hand, you can get a 105/4 Micro-Nikkor AI version for 130 USD, and it is still one of the best macro lenses ever made. So unless you use f/2 and f/2.8, the Zeiss might be somewhat academic. By similar comparison, the Zeiss 50/1.4 for f-mount is around 550 USD, and a Nikkor AIS version should sell for around 150 USD. The Zeiss has a different look and may be slightly sharper, as far as I can see on the samples posted, but for the difference in price it is rather academic on a D200. Not to say the same will be true on a 22 MP FF body, though. So they are to the general crowd a solution to a problem that doesn't exist, but to a minority of serious photographers they are a welcome addition to the arsenal of available lenses.
Bjorn Rorslett, Jan Wakker, Roland Vink and David Ruether have done extensive listings of MF Nikkors with ratings, links and what have you. If you are willing to do some reading, google those names and burn a few candles, and you'll know all there is to know about MF Nikkors.
