Hi Cesar, You are correct. The lens is called a "pre-set" lens. I suppose it is a step back from "automatic aperture" lenses, in that it is a manual process, but I kind of enjoy it. It does require a slower, more deliberate approach to photography....but then if you have an SV (as I do)...you already know that! Enjoy! Mike Steele
