PENTAX SP 16X50

The Pentax SP 16x50 is the most powerful model in the SP porro-prism line, combining 16x magnification with large 50 mm objectives for long-distance, marine and sky observation; a tripod is recommended at this power. Fully multi-coated optics and BaK4 prisms deliver bright, clear images, and a rigid aluminum-diecast body keeps the optics aligned for years of use.
