Field of view of each pick, widest first, from the makers' figures.

Why small objectives suit carrying

Nikon says optics with a smaller lens aperture are lighter and more compact, while larger objectives gather more light in dim conditions but add weight. Audubon adds that objectives smaller than 30 millimeters are easy to carry but not bright enough for detail in poor light.

The RSPB describes 25 mm objectives as light, small models for daytime use. The exit pupil is the objective divided by the magnification, as Nikon defines it, and on this list it works out to between 2.5 mm and 3.5 mm. Nikon puts the eye's pupil at about 2 mm in daylight, so by day these figures are enough. At dusk the pupil opens toward 7 mm, and a pair this size cannot fill it.

For a wider look at the trade, see compact against full-size binoculars and the exit pupil calculator.

Field of view and eye relief between the picks

Views run from 261 to 435 ft at 1,000 yd, with a median of 316 ft. Audubon says bird-worthy binoculars need at least 6.5 degrees, which it gives as 341 ft. The Nikon Trailblazer 10x25 ATB at 342 ft, the Celestron Outland X 8x25 at 432 ft and the Trailblazer II 8x25 at 435 ft all clear that mark. The Diamondback HD 8x28 reaches 6.2 degrees.

Eye relief is the weak point of the group. The median is 11.9 mm and only 2 of 10 pairs reach 16 mm or more. Eyeglass wearers should read how eye relief works and run the eyeglass check before choosing a pair at 9.3 mm or 10 mm.

Close focus and weight

The RSPB says close focus matters for insects, small mammals, reptiles and plants. The median close focus here is 9.9 ft. The Vortex Diamondback HD 8x28 focuses at 6 ft, the shortest of the ten. The Celestron Outland X 8x25 needs 16.4 ft, which suits distant subjects only.

Weight spans 6.9 oz to 13.7 oz, with a median of 11 oz. The four 10x25 pairs from Nikon, Swarovski and Celestron fall between 9.7 oz and 12.3 oz, so choose among them by field, close focus and price band. The 10x25 models and 8x25 models have their own pages.

What this list leaves out

Pairs with an objective above 28 mm or a weight above 14.1 oz are not here, so 8x32 and 10x42 models belong on other lists. None of the ten carries ED glass in the makers' documents. For daylight birding with more light, try binoculars for birding.

The short answer

For the lowest weight, the Nikon Aculon 8x21 at 6.9 oz fits. For the widest view, the Nikon Trailblazer II 8x25 reaches 435 ft. Choose the Vortex Diamondback HD 8x28 if you wear glasses, since its 18 mm eye relief is the longest here.
