  • Summary: Bought because I needed a relativly light weight modern lens-12oz for plastic bodied Pentax P30t SLR. Construction probably plastic and metal. Takes 55mm filters so size could be kept resonable. Balances well on camera. All markings prominently displayed. Like it also because has macro feature. Focusing ring could be a little tighter, but zooming feel is fine. Am still testing lens and camera with first roll of film.
