Just doing a quick memory check here: screw mount lenses, such as

thing for
the SMC Taks?

Yes, they work fine when manually stopped down to taking aperture.  
Metering is the same as with M/K-bayonet lenses: press the AE-Lock  
(or Green button on the D) and the body will set a shutter speed to  
match your aperture setting (presuming the aperture is stopped down).  
All auto exposure modes default to Aperture priority and, since  
you're stopping the lens down manually, it's actually a little more  
useful than with the M/K-bayonet lenses.

I find the M/K-bayonet operation with Manual mode and the AE-Lock  
button to be useful but a little clumsy. For lenses that I don't use  
often (like the M85 or Zenitar 16) it works well enough, but I prefer  
to stick with A series and later lenses so I can use all the metering  
facilities of the DS body.
