Variable aperture 3,5-4,5. Lens is labelled as “Kalimar”, its distributor. Maker or country of origin unknown (likely Japanese or maybe Korean). Lens must have been made in other popular mounts. No A/M switch, automatic diaphragm only. Aperture will not stop down when lens is used in a non-automatic diaphragm actuating camera. Two-touch zoom. May have 12 to 14 elements. Low distortion, somewhat lower contrast than equivalent prime lenses. Otherwise good performer. (JyJ)
