Universal 8x18 Optical Zoom Lens Micro Mobile Phone Lens Telescope Camera with Holder for iPhone Samsung HTC Android Smartphones (Black)

Good lens and mount. Mount made of thick aluminum and adjust to any size smartphone.

I bought this recently and asked for a refund pretty much within 20 minutes of using it. I thought maybe the adjustable clamps would hold better on my Galaxy s7 than the clip on type lenses. I tried this with and without the case on my phone and it wouldn't stay on the phone securely enough either way. Also, the zoom isn't very powerful. This is a 8x zoom NOT 18 like some others have said in their reviews. The 18 is the mm. I'm giving this 2 stars because even though it doesnt stay on the phone very well, it does zoom ok. Not great though. I bought a much cheaper clip on style lens on Amazon that stayed on the phone more securely and also had a better zoom distance. This one is a better lens. It works with the case on but it works better if I take the case off. Overall, it is a much better lense... https://www.amazon.com/gp/product/B071JRWWJS/ref=oh_aui_detailpage_o05_s00?ie=UTF8&psc=1

Well, it's OK and it does work. But just what I thought might be a problem, is a problem. The grip on each side of the mounting piece that holds the unit onto the phone is 3/8ths of an inch. If you have a phone case that adds practically any thickness to your phone, it won't mount, when you tighten it it pops off. Normally I'd send it back, but I think I can add something to the sides of the mount to hold it on with the case on the phone. If you don't have a case on, it holds well. The photos I took were the first two I took, you have to remember that these are like binoculars, so you have to hold it almost perfectly still to get a clear photo.

Looks like it should work with most cell phones, but don't try it if you have a protective jacket, it won't fit. It's almost impossible to adjust the mounting bracket and the placement of the lens at the same time. The optics are terrible, lots of barrel distortion. The field of view is restricted on normal camera setting but full field only on zoom. Never could get it to focus properly. Returned.

I’ve now used this for my son’s track meets, and multiple Christmas and end of year performances of my children. It’s ncie to be 18 rows back and still be able to focus in on my child. Fits my Galaxy S5 just great. A bit of circulizing the picture, but not bad.

LIKE IT. GMB

This one isnt2too good either but may be better than that previous one. Hard to keep in place. Is NOT a telephoto as advertised only a magnification. It does not change focal lengths as the description says. False advertising

came as advertised and fits on my IPhone as instructed but the lense is too small and puts a black ring around the scene in the picture.Actual picture area is about 70% of the whole screen area.
