Nice condition zoom. Heavy, but compact. The "Series 1" line was Vivitar's attempt to produce lenses that matched big name brands' image and build quality. Focal length range goes from moderate wide angle to short telephoto. Is a "push-pull" type zoom with macro capability. Focus, zoom and aperture all work smoothly. Aperture range is f/2.8-3.8 to 22. Blades are in good shape. Glass is also in good shape. No haze or fungus, some dust which does not appear to affect images. The macro focusing capability goes down to 1:2 at 28mm. Minor cosmetic wear. Includes caps and a haze filter. Please review photos and test pictures. Test images are Sony jpgs (full frame sensor) and are straight out of camera.
