Pentax DA 21987 35mm
Its 124g weight and weather sealing distinguish this Pentax 35mm f/2.4 APS-C prime, which uses Super Protect coating and a fast f/2.4 maximum aperture for a natural perspective. The lens provides a budget-friendly entry to prime shooting, with six elements including an aspherical lens for sharp edge-to-edge resolution and a pleasingly blurred background. It suits Pentax DSLR beginners and travel photographers seeking an ultralight, all-weather wide-angle lens for everyday snapshots.
