I've wondered about this for some time. There are essentially two way the electric pins frm the camera body to the lens can be configured: either pointing forward like in the Canon bodies, or pointing towards the center like the Nikon bodies.
I have noticed in the recent teasers from Nikon that they are adopting the Canon style pins. Are there any obvious advantages to this configuration?
PS. I am not sure if this question fits better here in Photography or Electronics.
