How To Attach Cell Phone To Binoculars

So you want to attach your cell phone to your binoculars, but don't know how? There are a few ways this can be done.

Attach your cell phone to a set of binoculars, and you'll be able to shoot pictures or record video inherently. All you need is a little ingenuity! Your camera's viewfinder will function as the eyepiece, which means focusing will be automatic.

Fortunately, using a smartphone or an array of smart devices can help you attach your smartphone to binoculars and keep your hands free for something else! With this in mind, here’s how to attach a smartphone to binoculars.

Way To Attach Cell Phone To Binoculars

Remove the Neck Strap

Remove the neck strap from your binoculars as it may interfere with your smartphone while attaching other materials.

Use Rubber Straps

Use four rubber straps to attach smartphone to your binoculars. Rubber straps should be across the left side and right side (use 2 each side) of the phone using loops on each strap. Stretch the third strap across to the right side, snapping it on. The rubber straps should be placed about 1 to 2 inches from each other and should not cover up the lens cap.

The rubber straps will hold the device in place and prevent it from sliding down as you take images or videos. They will help the smartphone grip onto your binoculars using its tripod mount socket.

Smartphone with Objective Lens Caps

Place your phone with the objective lens closed & sitting down on a surface. Position your binoculars so that the long tube of the body fits into the hole in your phone where it meets the back. Hold both binoculars and smartphone securely and then focus them on a nearby object. Once you have successfully focused them, then twist one end of the long tube attached to your smartphone around to secure it onto your binoculars.

Eyecups of Binoculars with Camera Lens

After attaching the rubber straps, align the eyecups of the binoculars with your smartphone’s camera lens. You may need to try various positions to ensure that you’re setting the correct distance. After aligning all eyepieces, you can pivot your device slightly outwards and start focusing. The distance between the smartphone camera lens and the binoculars should be as close as possible without hitting anything.

Active Phone Camera App

If you want to capture pictures or video footage, then this will be necessary. If you want to capture audio, then you should also turn on the phone’s recording function. This way, you can take advantage of the smartphone’s microphone and record anything you want. For example, if you’re an avid birdwatcher, then you may want to find birds through your binoculars. You can also try recording anything else you see or hear!

Zoom in to fill the mobile screen

The final step in this process is much simpler than the others. When you’re ready to use the phone as a viewfinder, you should zoom in until the screen fills your view completely. The number of steps involved in this process may look daunting at first, but this is what you get with smartphone attachments to binoculars. You can use these solutions to binoculars whenever you want and there are no real downsides.

The best thing about smartphone attachments to binoculars is that they don’t require any extra hardware or software. All you need is a smartphone and some rubber straps, eyepieces and a way to attach the device to your binoculars. Of course, you can add other features to your smartphone through add-ons.

Final thoughts

Consolidation … of images onto a single, larger screen means that phone viewing angle is less important. The only thing that matters is that, in order for the phone to sit up straight and aligned with the binoculars, it must be mounted on top of the binoculars with the lens cap facing down. I fumbled around with my cell phone for what seemed like an hour trying to get it just right. The rubber bumpers underneath the case kept sliding off and it took forever to get them back on again.
