Vivitar 105mm F/2.5 Series 1 VMC Macro A Manual Focus Lens For Pentax K Mount Review

The Vivitar 105mm F/2.5 Series 1 VMC Macro A is a legacy manual focus lens designed for Pentax K-mount cameras. Part of Vivitar's higher-end Series 1 line, this macro-oriented lens offers a useful focal length for portrait and close-up work at a budget price point. It features multi-coated optics (VMC) and a 52mm filter thread.

As a used, third-party manual lens from the film era, it requires full manual operation (focus and aperture) and compatibility with Pentax bodies that support K-mount. Availability through KEH in excellent condition suggests the lens has been well-maintained, though typical wear and potential optical imperfections are inherent to vintage glass at this price. It's a practical option for photographers who already own Pentax cameras and want an affordable manual macro without investing in modern optics.
