    Overview

    The SMC Pentax-F Zoom 35-105 mm f/4-5.6 is a versatile lens from the late 1980s, compatible with modern Pentax DSLRs and offering full PASM control. Its optical strengths include a useful macro range at the telephoto end, allowing close focusing to about 0.2m, which provides a unique perspective not easily matched by primes. Weaknesses include a slow variable aperture (f/4-5.6) and a disappointing minimum focus of 0.7m outside macro mode. Build is lightweight and compact, with a plasticky feel typical of its era. This lens suits photographers who value its macro capability and convenience over prime-lens speed or ultimate sharpness.
