Half the weight, half the glass, one eye · review
A 12x52 monocular with a 22 mm eyepiece, BAK4 prisms, twin focus rings and a 1/4-20 tripod thread, supplied with a case, strap and lanyard.
The bottom line The monocular on this shelf built to be put on something — and at twelve times, that is the specification that matters most.
A 1/4-20 BSW tripod socket, named as such. It is the smaller of the two threads defined for photographic tripods, and it means this monocular can be mounted on anything from a table clamp to a full tripod. At twelve times magnification, that turns a shaky view into a steady one, and no coating claim does as much.
Fifty-two millimetres of objective, a 22 mm eyepiece lens, a 4.3 mm exit pupil, and a published field of 85 m at 1000 m. That last figure is roughly four and three-quarter degrees — narrower than the widest here and comparable, because it is a number.
Ninety-nine point nine per cent light transmission, without a wavelength. Reported as published, and not treated as a specification.
Case, hand strap and neck lanyard, plus a stated two-year warranty. For an instrument intended to live in a bag, the case is the part that decides whether the objective is still clear next year.
German and French Amazon stores ran from 33 € to 50 € on the day of the survey.
Italian and Spanish Amazon stores stood above 1.6× the cheapest country. A gap that size normally means stock forwarded from abroad rather than a seller on the ground, so those figures are left out of the range above.
American and British Amazon catalogues hold a record for it that nobody is selling.

At twelve times, hand tremor hides detail that the optics would otherwise show. A 1/4-20 thread — the standard photographic size defined in ISO 1222 — means any photo tripod or clamp will hold it.
Eighty-five metres at a thousand is a little under five degrees. It is narrower than the widest monoculars here, and it is published, which makes it comparable.
