Description — Pentax 28-105mm f/3.5-5.6 ED DC WR
The HD PENTAX-D FA 28-105mm f/3.5-5.6 is a Full Frame standard zoom lens built for the Pentax K mount DSLR system. It spans a 28–105mm focal length range, covering wide-angle through short telephoto in a single lens, making it a practical choice for photographers who want versatility without carrying multiple primes. The maximum aperture of f/3.5 at the wide end provides reasonable light-gathering capability, though the aperture is variable across the zoom range.
Autofocus and manual focus are both supported, offering shooting flexibility across different subjects and styles.
