Four published figures

Eyepieces from 28 to 49 mm. Phones from 65 to 105 mm. A hundred and fifty by eighty-five by forty millimetres. Eighty-eight grams. That is more numerical detail than most of this shelf offers, and every one of the four decides whether it will work with what you own.

The rotating holder

The maker describes it as designed to avoid pressing the volume and power buttons. Anyone who has clamped a phone across its side buttons in the dark knows why that matters: the phone locks, the volume jumps, and the shot is gone.

Rubber and EVA

Soft materials protect the phone and flex under load. For a hand-held binocular that is the right trade; for a long session on a tripod a stiffer frame keeps the alignment longer.

The text it shares

The same five bullets appear on another adapter here under a different seller name, with one number changed. Both are reported as published.

Availability

German, French, Italian and Spanish Amazon stores ran from 14 € to 20 € on the day of the survey.
