[0.35 lb] We, Save Our Sandhill Cranes, do free public crane viewing tours. We provide spotting scopes which our guests try to use to take pictures with their smart phone cameras. They get so frustrated trying to hold the cameras just right. It is near impossible to get a decent picture. Now, however, we bring this adapter along for our guests to use. It fits most cameras. Our guests love it. It has increased our donations.

[10" (25 cm)] Great small size. Real clear and easy to see thru. Easy to hold steady because of the small size

[10" (25 cm)] An attractive, fun, sturdy practical design allowing easy coupling of my smartphone with a variety of microscope oculars and those of binoculars and monoculars as well. Very pleased with its performance.

[0.35 lb] I use this on my celestron 127eq telescope. Product is easy to use and adjust to my iPhone 7. Got some nice pictures of the moon in my driveway. The planets are a bit tricky since they move fast. Takes a bit of adjustment to center the camera to the eye piece but worth the effort.

[10" (25 cm)] Very nice. Perfect for my needs.

[10" (25 cm)] Brought this model adaptor because it looked solid and well made and well padded compared to other ones I looked at. I have only used it once so far but I am so impressed. I was able to take very good pictures and it was so easy to use. I love it and would highly recommend this model of adapter. Thanks B&H.

[1.2 oz (34 g)] This is way better than similar products I have owned from other brands. Not only is it extremely sharp in the center, it stays sharp out to the edges, and the field of view is surprisingly wide. A tremendous value for the performance. This is actually the second Carson monocular I own, and I'm very pleased with both. Only slight nit is that this 6x18 doesn't focus all that close up, maybe 10-12 feet is the closest it gets, but if that's the trade-off for the superior image quality at longer distances I'm willing to accept that.

[10" (25 cm)] Purchased this as a gift or a golfer who really liked it and also another for myself to take along on bike rides. Good light weight and handy.

[10" (25 cm)] I wasn't actually expecting it to work based on the price and size, but it does exactly what I wanted. I'm not quite 20/20 wearing my glasses, and I was having trouble identifying winter finches or distinguishing them from sparrows at the tops of trees, and wanted something small enough to slip into my pocket for my daily walk. This doesn't help me with unexpected birds very far away, but is enough to get the extra details or a little bit of color to confirm them if I already have a pretty good idea of what I'm looking at.

[0.35 lb] very useful and handy to see far signs.
