Due to its small size and light weight, it is ideal as a handy and mobile "glass" (especially with a small "Olympus E-PL1" or Panasonic GF1). The lens is fully MANUAL. It has two rings: focusing and aperture adjustment. Very "climatic" glass, beautiful color rendering and sharpness! In pictures you can see how it "draws" and how it adds character to the pictures. The lens can be successfully used on cameras such as the Nikon 1, Pentax Q, Sony Nex and the BMPCC camera (Black Magic Pocket Cinema Camera) of course using a suitable adapter for the aforementioned systems.
