Great binoculars

The lens and eye piece caps have a really loose fit. They fall off without much effort. Other than that these binoculars are excellent.

Pentax SP 10x50 WP

The Porro SP WP series produced by Pentax was launched on the market in 2015 superseding PCF WP devices. In practice it meant the barrel was changed a bit and 7x50 and 16x60 models disappeared from the line-up, leaving instruments with the following parameters: 8x40, 10x50, 12x50 and 20x60.

solid-looking and completely waterproof casing; good colour rendering; BaK-4 glass prisms; negligible distortion; imperceptible brightness loss on the edge of the field of view; excellent blackening and cleanliness inside tubes; sensible antireflection coatings; 30-year warranty period

narrow field of view with mediocre sharpness on edges; a bit truncated exit pupils
