 The body of the lens is build from **metal**, so it feels sturdy and solid. The aperture ring does not have mechanical feedback over the stops: it turns smoothly from **f/1.8** to **f/16** with a little friction, so it should not move inadvertently.
 The focus ring also has a little friction that should prevent unwanted moves, the external element does not rotate on focusing, so you can mount e.g. a **49 mm polarizer filter** and it will **not rotate** on focusing. A depth of field scale is printed on the lens body (but it is **totally wrong**, see below).
