Two eyes, a wide field, and no setup at all · review
A 12x50 with an 18 mm prism and 50 mm objectives, supplied with a carry case, neck strap and cleaning cloth.
The bottom line A higher-magnification 50 mm that gives up some of its light advantage to the arithmetic of the exit pupil.
Fifty millimetres divided by twelve gives a 4.2 mm exit pupil. A dark-adapted adult eye opens wider than that, so some of what these objectives collect never reaches the retina. Against the 12x42 pairs nearby, this is still the brighter choice; against a 10x50, it is not.
A darker sky background. On a double star or a small cluster, twelve times separates what ten leaves blended — provided the view is steady enough to see it, which brings the discussion back to holding.
Eighteen millimetres, published. Prism size decides whether the full light cone from the objective gets through without being clipped, and it is almost never stated. Whether it is adequate here cannot be determined from the listing alone, but the number being present is worth noting.
Case, strap, cleaning cloth. No tripod adapter, and no tripod thread is mentioned — which at twelve times is the accessory that would most improve what these show.

Not straightforwardly. The higher magnification darkens the sky background, which can help on some targets, and the smaller exit pupil delivers less light to a dark-adapted eye. The steadiness cost is the bigger practical difference.
It describes the prism’s size, which has to be large enough not to clip the light cone from the objective. An undersized prism vignettes the image; publishing the figure at least allows the question to be asked.
