The Good
The Bad



In case you’re trying to find the best scope cell phone adapter mount for your smartphone but have no idea which one is the most stable or you have doubts about compatibility, then you’re in the right place. Read the following guide and get all the info you need to make an adequate choice and pick the adapter that suits your needs.


If you want to get one of the most durable adapters for sale, then you need to make sure that you go for one that’s made of tough materials. You can choose a unit that’s built with aluminum or another metal, hard thermoplastics, etc. That way, you enjoy a proper support as well as a long service life.

Most of these mounts usually consist of a mobile phone holder and an eyepiece holder. The former can either come with a suction cup or a clamp. The clamp models can be loosened or tightened via a large knob and screw. The great thing is that these are usually fitted with rubber or EVA pads which ensure that you won’t get your beloved iPhone scratched while using it.

The other piece usually has two parts that form a rhombus which gets larger or smaller with each turn of its large screw. Depending on the model, this part may take another shape, and it could be tiny or large so make sure you do some proper research before buying.


Versatility and compatibility

One of the advantages of getting a mobile phone adapter mount is that you can use it in many ways and with lots of devices. You can easily attach your smartphone to your compact monocular for hiking, study algae and cell tissue on a microscope or even connect to a large telescope and take a snapshot of the Moon or other celestial objects.

You get endless possibilities with such an adapter. What’s important is to remember that the part that attaches to the eyepiece has an upper limit so you need to check what that is to ensure it fits your optical instrument. The phone holder has a wider range so you’ll probably be able to use it with just about any modern phone.

Most models can usually fit on eyepieces ranging from 25mm to 45mm or 0.965 and 1.77. This makes them compatible with most scopes, binoculars, and microscopes. However, they will not work with large 2-inch telescope eyepieces, nor with some rifle scopes or some variants with fold-down eyecups. Make sure that you check specifications before you buy.


Portability and other considerations

The great thing about these mounts is that they’re normally very light so you’d best stick to a model that doesn’t go over 4 ounces or so. Getting a heavier mount might beat its purpose, especially when you’re supposed to use it with a mobile phone that’s also light.

Opting for a lightweight unit ensures enhanced portability so that you can put it into your backpack or even pocket and forget about it until you need it. You might also want to consider getting a product that has a ¼-20” socket so that you can use it with a regular tripod as well if you need to.

Another advice would be to make sure that all clamps come with rubber or plastic pads in order to avoid unwanted scratches. These pads are also great for improving grip.
