Monocular Telescope 300x40 High Definition Monocular Lightweight Monocular with Phone Adapter & BAK4 Prism & FMC Lens

The "1000x magnification" is pure nonsense; the seller clearly knows nothing about it. At most, one can say that the magnification is around 10x, with measurements to back it up (at 13.5m, the field of view is about 1.3m. Not less).. It would be interesting if the seller understood what the markings on the eyepiece mean, and on which they are basing their information: "1000X20mm - 96m/100,000 m". - 20mm is the diameter of the front lens, ok. - 1000X is supposed to represent the magnification. Except that: at 100km (100,000m) the width of the field of view is on the order of 10km (10,000m) and not at all 96m ! If that were the case, it would be an incredible performance for such a tiny monocular.. These misleading indications are therefore purely marketing, and it would be wise for the seller to correct them at least in the title and its detailed description, instead of telling us that it would withstand an earthquake! :-)) That said, apart from the bizarre announced performance, this small monocular still allows you to perceive inaccessible details on buildings or in nature which are quite satisfactory for such a small object and its low price, and at least testifies to a fairly good optical quality. So I'm still leaving a few stars. Attention: seems a bit fragile on the focus adjustment side. So handle with care if you want it to last a while.

Small, looks okay. There is focus for vision.
