Vivitar 28-50mm f/3.5-4.5 PK Lens
100-Day Warranty
Focusing, zoom, and aperture are in good working condition. Optics are clean with no scratches or fungus, with very little haze and dust inside. I love this lens for being very compact, and it is ideal for street photography. The lens can be mounted on Pentax D-SLR digital cameras, but focusing will be manual. Aperture priority is a good setting for digital cameras.
The Vivitar 28-50mm f/3.5-4.5 PK is a vintage, manual-focus zoom lens featuring a Pentax K (PK) mount. It covers a compact focal range from a wide-angle 28mm to a standard 50mm perspective.
