Summary: Over the decades, I have compared all of the very best binoculars available at any price. While I have owned the EL which is really quite comparable to my Leica Ultravid 10x42, none others are in the same highest class. After settling for lesser quality mini binoculars for a long time, I finally ordered the Leica Ultravid 10x25, and have used them for a year now. They are outstanding in every respect.
Summary: These are impressive binoculars considering how small and light they are. Not quite as bright as my pair of monarch 10x42's at dusk, but still much better than expected. I'm not worried about missing anything during hunting hours (30 min before sunrise and after sunset). They are definitely much sharper than my 10x42's, especially toward the edges. After a little practice they get much easier to use. Now for a word of caution: the description for these is inaccurate.
Summary: I've owned the Leica 10x25 binoculars for 3 fall hunting seasons and the brightness near dusk is the best for the size, in my opinion. I also own the equivalent Swarovski 10x25 binouclars and have been using them for 2 fall hunting seasons. Both are excellent and I, and my sons, have used them in snow and rain and in bright light and at dawn and dusk in Colorado and Wyoming. Each has its advantages.
Summary: These binoculars are better than any 8x30 binoculars I ever had but weigh less than 250 g and fit in a shirt pocket. Brightness and clarity are just amazing. When my wife and I go birding and I ask her whether she wants to carry the 10x42 "S" brand (also outstanding binoculars) or the compact Leica Ultravid she now prefers the lightweight Ultravid. The only thing I'm missing are lens caps.
Summary: Acquired binocular to replace damaged Nikon 10*25. Complements existing Leica 7*42 and Swarovski 10*42. Used as a portable when a small lightweight binocular is more convenient. Did not expect it to outperform larger binos and it does not, but it is brighter than the Nikon. It lives up to expectations. Did find it a bit of getting used to in the beginning.
Summary: This "jewel" is possibly the best available binocular for hikers and daytime nature observers it has excellent optics just like the larger Leicas ( My other one is a 10-15x50 Duovid) with the advantage of being light and easily carried in a pocket. It can be held and focus with just one hand and, still with one hand plus some practice, properly adjusted to your ocular distance.
Summary: Spent months researching compact binos for field, tactical and sporting use. These were the ones I chose and saved for. To date they have been excellent. I take them out while walking my bird dog and looking for dove on the plowed fields. Even in the fading evening light, these binos are bright and clear. I've had them out well into the evening and they continue to provide much clearer views than I would have expected with the low light available.
Summary: Wow. Very impressive set of binoculars. Small, light and VERY GOOD image quality. Use it to watch birds and amazed at feather detail I can see as compared to a more mainstream pair of binoculars
Summary: The binocs work well but are limited in their field of view. I have a pair of the 8x30 full size Lica binocs and they are much brighter with a much wider field of view. I expected the difference but was amazed how much of a difference there was. It is a little hard to pick up objects with these glasses. On the plus side, they are very easy to carry and the optics are second to none.
Summary: Let's face it, forking over $1,800+ for a set of binoculars isn't something to be taken lightly and the product better be worth what they cost. Like many here, I also did a side-by-side comparison with top-of-the-line models from Swaro, Zeiss and Lecia and gradually became more impressed with the Leica 10X42 Ultravid above all the others.
