One advantage of a 50 over the 40 is the field of view (area surrounding the target). A lot of difference if you compare a 4x15 (22 scope) or your 3-9x50 set on 4x. Besides the light gathering qualities, that is one of the main reasons that the scope manufactures upped the front lens sizes. A lot of the old scopes had a 32 or 35 lens. Then they went to 40, and then the 44 and now they even go up to 56.
