Eyeskey Universal Phone Adapter - Capture Stunning Moments with Your Smartphone Through Binoculars, Monoculars, Scopes, Telescopes, and Microscopes - Fits Most Smartphones

I bought this to attach my pixel and my wife's samsung phones to a pair of good binoculars to use as a simple telephoto. The way the ring attaches to the binoculars is very stable and grips well. It is easy to line up your phones camera first with the hole in the ring, and then attach the ring to the binoculars. The bottom holds the phones firmly without pushing the buttons on the side and does not move around, so once you get things lined up you're good to go. I do not think this is a good substitute for a serious telephoto lens, but for our purposes, a lightweight easy way to use our phones to take pictures far away, it's just fine. Nicely engineered.

I really wanted to like this but could never get it to keep the camera in place on the binoculars. I tried tightening all of the screws many times, but this just would not stay in place. My 35mm camera telephoto lens is 8x magnification and this would have provided 10x magnification through my binoculars so I was very excited to use this on a recent wildlife viewing trip. Other people on the trip also had binoculars (and cell phones) and were really interested in this product. Unfortunately, we could get the product on the phone, but the minute we then put in on the binoculars, it would move off lens; it was very frustrating. I have an iPhone14 so maybe it isn't meant for this model. I love the concept so I'll probably try to get a different brand that is a little more reliable.

Honestly it’s not bad but it doesn’t work well with my binoculars because my binoculars is too heavy and it shifts the camera position every time.

Wish the part that held the phone was spring loaded. Other than that, it works very well on microscope oculars.

Great concept but my apple phone has three camera's so zoom changes everything making this poo poo and can’t be used after dusk, honestly just get yourself a spotting scope. May work well but not with my apple. You will need a tripod as well unless one can hold perfectly still. I have serious doubts that military would use such a setup, as a cheap kids toy okay but nothing more

Robust, well made, works well! S24. Used on both astronomical 80x20 binoculars and a telescope. Kids got to see Jupiter this summer!

The device had all the attachments, and I think it might work if the cell phone were light enough. The weight of the phone makes it impossible. Wish it had worked.

Me gusto

This is a totally honest assessment and opinion. I have an Olympus DPSI 10x50 set of binoculars and a tripod which I use for other photography work. I own a Motorola Android phone which I attach to my binoculars using this adapter. When secured to the tripod the resulting view and photographs I can take of my bird feeders which is about 12 metres away is nothing short of spectacular, it is like being right next to the station when the birds are feeding. Initially it can be fiddly to set up but the results are worth it.
