Pentax D FA 15-30mm f/2.8 ED SDM WR 30mm
The constant f/2.8 aperture across the 15-30mm zoom range pairs with ED glass and HD coatings to deliver corner-to-corner sharpness and contrast. Weather-resistant sealing and fast, near-silent SDM autofocus make it dependable for outdoor stills and video in rain or dust. Best for Pentax K-mount landscape and astrophotography shooters who need a durable, bright ultra-wide zoom with consistent low-light performance.
