By packing high-end features within an affordable, reliable pair of binoculars, the SP 8x40s are a welcome addition to the expansive Pentax S-series. Centred around a key 8x magnification with 40mm objective lenses, these binoculars integrate high-quality BaK4 prisms to further enhance light transmission and resolution. The fully multi coated and anti-reflective interior optics produce clear, crisp, and colour-accurate images suited to bird watching, walks in nature, and more. Due to their durable and hard-wearing exterior construction, the Pentax SP 8x40s are well-suited to viewing contrast-rich, bright images under harsh weather conditions. This is further backed up by the aluminium die-cast body, tactile rubberised armour, and large knurled central focusing wheel.
