Thread: Question about scipe sharpness of definition

While I cannot speak to the "sharpness" of the image, a fixed 6 versus a varipower set on 6 of the same physical dimensions (eg a 6x40 versus a 3-9x40 as your OP) the fixed will be lighter and will have a wider field of view. The simpler construction internally usually means the fixed power scopes have less to go wrong and are more robust scopes
