My wife has the Nikon 50mm f/1.4 G for her photography, and I was thinking of seizing this away from her for the GH2. Unfortunately, it's not a D, but a G - so my question is if I get the Novoflex adapter, will it work with the GH2? If I have the G and the Novoflex, is there any advantage to having the D instead of the G? If so, I might trade it in
