I have a Lumix G7 and want to use a Canon FD lens with it (mostly because of the incredible price).
The FD lenses I have in mind are the 28mm F2,8 and the 50mm F1,4. I know that the focal length changes with an adapter, I just can't really figure out by how much.
Does the f-number change too? So from F2,8 to F4 or something like that?
