Summary: I own both Trinovids and this Ultravid. I really appreciate the Leica glass and decades of camera engineering. The Ultravid coatings are second to none. The center focus knob makes these stand out from the other Leicas. I paid extra $$ for the Ultravid and I am pleased. I may even sell an older Trinovid now.
Summary: Being in the optics biz, I have bought and evaluated MANY compact binocs. The Leicas are simply the best. They have a flat field edge to edge (much better than the Zeiss compacts) excellent color rendition, no chromatic effects, and provide a very bright image for their aperture. I find the Leica Germany compacts to be just a little bit better than the ones made by Leica in Portugal. It shouldn't be so, but....there it is.
Summary: I have a standard pair of Zeiss binos for my trips to Africa but I wanted a light and bright pair for bird watching and star gazing while on extended backpacking trips. The Leica Trinovids do the trick. Extremely sharp and light. My only concern is holding them steady. If steady is a concern for you - don't get the 10 power. But these are superb binos.
Pros: Compact, Quality Lenses, Strong Construction, Works Well With Glasses
Summary: This is the ultimate in a compact binocular with the famous Leica lens quality! These are lightweight, small, and fit on your belt so are easy to take to the opera or symphony as well as on a walk or hike to look at a bird or other wildlife. As with all Leica equipment, they are very expensive, but the lens sharpness and quality are unparalleled.
Pros: Close Focus, Compact, Quality Lenses, Strong Construction, Works Well With Glasses
Summary: It's always worth spending the most you can afford on optical equipment. You can find binoculars that are much cheaper than these, but their performance pales into insignificance if you try these and the cheaper ones at the same time. Go on, go for it!
Summary: These may look small and leave you feeling they'd not be up to much but.... Wow! They're truly amazing. Fantastic for bird-watching and quite a surprise for this when you normally think that approx "8 x 42s" are the bees knees. These are expensive but they are really worth it. Easy to carry around in a pocket if you don't want them round your neck and then very quick to "wheel-up" and focus. Brilliant little things these. Treat yourself!
Summary: From early use, the binoculars themselves seem excellent. However, I have pointed out to Leica that the supplied carrying case is rather more bulky than that supplied with similar Trinovid binocs which I bought some years ago. It is less convenient for putting into pocket or handbag. This is a little disappointing since, after optical performance, portability is a prime property of 10x25 and 8x20 binocs.
