Tamron SP 24-135mm f/3.5-5.6 Aspherical Macro AD IF Lens for Pentax K-Mount Review

The Tamron SP 24-135mm f/3.5-5.6 Aspherical Macro AD IF is a versatile all-in-one zoom designed for Pentax K-mount cameras. With a focal range spanning wide angle to telephoto and a macro capability, it offers broad coverage for general photography without the need to swap lenses. The variable aperture and older optical design place it firmly in the budget superzoom category, aimed at users prioritizing convenience and reach over ultimate optical performance.

This particular listing is a used unit in excellent-plus condition from KEH, priced at $160 and including caps and hood. As a legacy lens, it lacks modern coatings and autofocus motors found in current designs, but it remains a functional option for Pentax shooters seeking an inexpensive, flexible walk-around lens. The macro feature adds close-focusing utility, though the narrower maximum aperture limits low-light performance and depth-of-field control.
