I'm looking into prime lenses (50mm or so) for a D40. The AF-S lens
that works with the D40 is a little expensive. I don't mind having to
manually focus AF lenses, but I find their focusing rings to be a
little thin and loose.

Are there any Manual focus lenses that have electronic aperture
control?

If I use a completely manual lens I guess I will have to shoot in
complete manual mode, adjust speed and aperture on the camera until
exposure is correct, then stop down the lens aperture before taking
the shot. Is that right?

I think what you might be looking for is the Nikon 45mm f/2.8P
"pancake" lens. This is manual focus but has the computer chip for
automated exposure functions.

This lens was introduced with the FM3A but has been discontinued. You
can find them on ebay etc. but they're rather pricey.

Manual focussing with the D40 is greatly facilitated by using the
aftermarket "Katz Eye" screen.

Absolutely. You are looking for a lens with an AI-P designation. They
were built towards the end of the 80s.
Or an even older AI lens (from 1977 onward) with an added chip which
effectively converts it to a AI-P.

Just a handfull of specialty pro oddballs beside that like 500mm f/4 P
and PC-Micro 85mm f/2.8 D. People used to splice chips and electrical
contacts into old lenses but that's uncommon.
