Vivitar 35-70mm F/3.5-4.8 Macro 2-Touch Manual Focus Lens For Pentax K Mount Review

The Vivitar 35-70mm F/3.5-4.8 Macro 2-Touch is a legacy manual focus zoom lens designed for Pentax K mount cameras. Built in an era when Vivitar offered affordable third-party optics, this lens features the classic two-touch design with separate rings for zoom and focus, along with a macro mode for close-up work. The variable F/3.5-4.8 aperture is typical for budget zooms of its generation, and the 52mm filter thread keeps accessory costs low.

At $19 for a used copy in bargain condition, this lens is priced for experimenters, film shooters, or anyone curious about manual focus glass without financial commitment. Expect signs of wear and potential optical or mechanical quirks given the grade. It will work on modern Pentax DSLRs and mirrorless bodies with adapters, though you'll be focusing and metering manually. The macro capability adds some versatility, though true macro performance from vintage third-party glass tends to be modest.
