Tamron 28-80mm F/3.5-5.6 (77D) Aspherical Black Autofocus Lens For Pentax K Mount Review

The Tamron 28-80mm F/3.5-5.6 (77D) is a compact standard zoom lens designed for Pentax K-mount cameras. With a focal range covering wide-angle to short telephoto and a variable aperture, it's a typical kit-style lens from Tamron's back catalog. The aspherical element helps control distortion across the zoom range, and the autofocus system is compatible with Pentax film and digital bodies that support screw-drive AF.

At a $20 price point in bargain (BGN) condition from KEH, this is strictly a budget option for those building out a Pentax film kit or looking for an inexpensive beater zoom. Optical performance and build quality reflect the era and price tier, so expectations should be modest. It's functional glass for casual shooting or backup duty, but not a lens you'd lean on for serious work or demanding image quality.
