However, greater magnification results in more exaggerated movement from shaky hands or other slight movement. Otherwise, the 12x42s offer the same features as the 10x42s, namely: a porro prism system, multi-coated optics and being 100% waterproof.
The 12x42s' porro prism system offers greater depth perception and a wider field-of-view than roof prism systems at the cost of the streamlined design that roof prism systems offer by way of the front lens being offset from the eyepiece. Their multi-coated optics provide the 12x42s with greater light transmission and reduced glare for a clearer, brighter image. Additionally, the 12x42s are O-ring sealed and nitrogen purged for binoculars that can handle even the wettest conditions without resulting in internal damage.
