I bought these as a complement and compact version of its larger brother 10x42 Pentax binoculars that I already had. Excellent optics that rival those of Leica or Zeiss that cost much more. I looked at both of those brands, which are also excellent, but I could not find very much more added vaIue for the price. I particularly like the compact size and light weight. If there is a negative, it would be the rainguard lens cap which is a little oversized and not very tight and possibly easier to knock off and lose than others if not attached to the strap, but not really a big deal. Highly recommended.

this are great binoculars, quality of the product is out standing. defentlyi will recomend this product
