A great lens to own. You will still be using this wonderful glass into your 4th or 5th Camera upgrade... in the next decade or so. It's that good. It's like having a 50mm lens on a cropped 1.6x sensor. Same FOV.
Bang great AF accuracy with manual overide; No moving parts; no focus barrel movements; Weird but wonderfull lens hood; (Try attaching the hood in reverse and let them go crazy trying to figure out what kind of lens you got; because it looks...weird! Try it it; its fun.
Easily spotted by photographer friends and asked to be borrowed..; annoying
