Query: Outstanding binoculars

I have used Pentax lenses for photography for many years. Pentax optics are legendary.My most recent purchases include the so-called "Limited" and "Star DA" lenses by Pentax. They perform very well in my photographic endeavors - delivering stunning images with excellent sharpness, contrast, color, detail and "bokeh".Looking for a pair of binoculars for bird watching, wildlife and general scenery, and based on the positive reviews of this pair of 10x43 DCF SP found on different web sites, I can only say that they match my expectations of optical excellence.Looking at hummingbirds close-up (close focusing) opened an entirely new perspective on these colorful little hummers...Eye-relief is excellent: I can use them with or without my glasses.These binocs are also sturdy, waterproof and dustproof, comfortable to hold and backed by Pentax' "no questions asked" life-time warranty.Highly recommended!
