Digiscope Binocular Eyepiece (Part 1 of 3)

Fits very well to the bino eyepiece.

Have several of these , one for each of my different optics. Most, all except this one, fit very securely to the optic. This one , for my Zeiss Conquest HDX 10x42, is way too loose. It will not stay on with the phone attached. Have to put a wrap of electrical tape to keep it on during use.

Great customer service. Quick shipping. Excellent product.

Fits Perfect! No complaints at all!

The Epoch mountain mag is an extremely convenient digiscope solution. The eyepiece is small enough to leave on for glassing when not digiscoping and the eyepiece is snug enough that you don't have to worry about it falling off. Being able to use your own phone case and not some goofy proprietary case is very nice, especially since that other one blocks your 4x/8x zoom lens on the iphone 17.

The only downside (which would occur no matter what system you run) is that unless you run the eyecups all the way out on the eye relief, the weight of your phone may cause the eyecup to rotate since the camera lens is not centered. This may not be a problem on other binos or a spotter if the eye cups have more tension when twisting them in and out, but I did notice it on my Zulu HDX's.

Last, make sure you download the Epoch camera app. When using the standard camera app on the iphone it would try to switch between lenses to focus if it did not like the image focus when snapping into the mag ring. With the epoch app, if you have the mag plate on the zoom lens, just click over to the zoom amount you want and it does not fuss around with trying to autofocus and switching lenses. Overall, very satisfied with the purchase and being able to capture some cool moments in the backcountry.
