Pentax SP 10x50 WP - binoculars' review
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.
