5 out of 5 eggsLeave it to Pentax!!

Pros: The image clarity of these binoculars is awesome! Some binoculars make you work to get into focus and once there you are liable to be out of focus after zooming. Not so the PENTAX 8-16x21 UCF Zoom II Binoculars. What you see through these lenses is a wonder to behold. definitely high quality glass and coatings. Light-gathering ability makes even dimly lit subjects view-able.

This instrument is light and small, which improves it's extended usage comfort factor, by a large margin.

The case back has 2 slots that allow secure belt attachment vs belt "clip on" types, which may easily be dislodged during climbing and other vigorous activities.

Diopter nob's "twist, to adjust & push in, to lock" system is a joy, especially if you are prone to loaning out your binoculars. Easy to remember your setting.

Diopter adjust, zoom, and focus are all in one column, making it needless to take your eyes away from the instrument to make any adjustment.

Eye relief can be left on and still fit in the case.

Underside tripod mounting plate is a welcome plus.

Cons: Should have made "cutouts" in the case's top edges (left and right), to allow the neck strap anchors to slide into the case more easily. A minor point to be sure.

An included neck relief pad should have been provided for the strap, rather than having rely on a 3rd party solution.

Other Thoughts: Birders will surely love the relatively low price. Good bang for the buck.
