Pentax DCF SW 8x25 Roof Prism Binocular


From Peter in MD:

5/5 Rating

I'm a birder, so these are the smallest binoculars I've ever bought, and my expectations were low as a result. I was pleasantly surprised at their optical quality, so I think they are a great choice if you need ones that are small and light, as they are an excellent value.

The Pentax DCF SW 8x25 binoculars have exceptional eye relief (they work well with glasses) and would be great for kids since the distance between the eyepieces can be very small.

They have a few drawbacks if you want to use these for birding. They have a limited field of view (only 288 feet), which makes it hard to watch a group of birds, and a limited depth of field, which makes it harder to get your subject into sharp focus. The focus knob would be easier to turn if it were larger.

They also seem dim in low light when compared to my 8x42 birding binoculars, and are a bit dimmer than the Pentax 8x28's I have (no longer made), but that's inevitable given the smaller objectives (25 mm). Gathering less light is not a big deal in good light, and they are much cheaper and smaller than either of the larger models.

Overall, these are great binoculars given their size and cost.
