Nikon G lens Aperture control dohickey

Nisio

Anyone know if you can get a convertor atachment to allow you to use G lenses on older bodies? Like some kind of extender tube atachment that would let you set the aperture?

edit:

like if you can get a nikon to canon adapter could you not get an aperture adapter?

I wouldn't imagine so, It'd be too complicated to engineer, and would be thick enough that you'd lose infinity focus. In fact you'd probably lose everything past about 10' or so. The Canon lens registration distance is shorter than the Nikon one ( and the nikon mount is narrower) which is why those doo-hickeys work. They wouldn't work in reverse.

-edit- Actually, the thickness issue could probably be solved with optics in the mount, you can buy M42 adapters for the F mount that allow infinity focus using this. However it'd need an aperture ring which would engage with the lens somehow and ALSO communicate correctly with the camera. You'd probably end up spending something far in excess of what a brace of classic primes would cost in the first place.

Now there's a comprehensive answer, thanks Daire!
