Pentax AD WP Reviews

It's all about the quality of the optics.

You can get binoculars with more magnification and a bigger objective lens for a fraction of the price of these, but you won't see as clearly. Yes, these binoculars are quite expensive, but you absolutely get your money's worth. With some binoculars, you can get a much bigger image of a distant objects, but without this kind of clarity, you won't get as much detail. It's all about the quality of the optics. These have first class Japanese optics -- the best in the world -- with astonishing clarity. Also, the combination of 9 by 28 is an excellent compromise that allows for a very steady image. They are quite compact and easy to carry around but deliver far betted viewing than most other compact binoculars.

Great pair of binoculars for the price. 9x magnification is a nice compromise. Optics give a really sharp image...good color reproduction and contrast. The focus ring I feel is a little bit sloppy but other than that I am very satisfied.

Would these be good for a person with a small face?
Asked by: Anonymous
Yes this model would be good for a small face. They fold up very small, so they will be able to adjust to the eyes well.
