Pentax SD 9x42 WP

Apart from that very specific transmission graph too high chromatic aberration is the only flaw of the tested Pentax; in other categories the binoculars fared decently well, good or even very good. The instrument didn’t have any problems with distortion, coma, astigmatism or brightness loss on edges of the field of view. What’s more, the optics is hidden inside a very robust, waterproof casing; you also get good quality prisms and 30 years of warranty period. The quality control also performed very well – the build, darkening and cleanliness inside the tubes is beyond reproach.
