and TTL flash metering.
Will those work? Or will I have to do all manual adjustments and manual metering etc?

I'm not concerned with autofocus.
I'd like to use an old Nikon 200mm/4.0 micro lens with a D100 or D70.

Thanks.

They'll probably announce a D200 in the next couple of weeks and there's a chance they'll work on that.

I occasionally use AIS lenses on a D100. Flash would suck but using them in manual isn't that bad because you can always take a test shot and check the histogram.
