The Pentax XCF 10x50 is very shape and lets in great light, distance viewing is great. The only problem for me is the close-up focal distance is not close enough, about 25 feet, I'm used to about 15 feet.

Needed an extra set (pair) of binoculars to keep in the car for unexpected birding moments and I am pleasantly surprised and pleased overall. After I received them I did a comparison with a pair of Nikon Action binoculars with the same specs. These binoculars give just as clear a view, and it is a fine, bright, clear view. The only difference I noticed between the two binoculars is that the Nikon binoculars give a bigger field of view in the circle. That is, I noticed a slightly larger black circle around the edges of the viewing circle with these Pentax binoculars. Still, they seem excellent for my application and I was able to recently view a nearby loon and duck with ease. These binoculars also are very well designed ergonomically, allowing me to get a good grip on them when holding them.
