Lens adapter for G2

Just ordered the G2 and was disappointed that Pan. does not have a lens adapter for Nikon lenses.  Anyone found an economical quality one?

there is one I have seen the Fotodiox one that is offered on Amazon and other places, its about $35.  My question is when you use an adapter like that, how do you calculate the focal length of the lens.  I know that using 35mm lenses on digital cameras is different than on the original film, because of the distance of the lens to the sensor, and the diameter of the lens.  But when you use the adapter, the lens is held further from the sensor, does that make it more equivalent or make it less, than the original focal length.

I'm not too smart about this either, but I think if you put a 50mm film lens on the 4/3m, you get the equivalent of a 25mm 4/3m lens. The lens won't work too well and you are basically on Manual.. The people that seem to use this the most, I think, are shooting videos.


However, if you have an old lens, let's say a 50mm, F1.4, you get a lot of light on the sensor.  Something like 2X a 1.7, and so on.

From what I have seen, really only Prime lenses are useful with the adapter.  Glass thats too expensive to replace.  So you would be right, only fast glass would be worth using.
