Which one to buy
Glasses wearers and travelers can stop reading after one comparison: the Opticron Traveller BGA ED 8x32 has 19mm of eye relief against the Nikon Monarch M7 10x42's 16.5mm, and it weighs 15.9 oz against 24.0 oz, at the same $550. Opticron owners say spectacle wearers see essentially the whole picture, and that it slips into a jacket pocket.
For everyone else, the question is reach versus width. The Opticron's 429 ft field is among the widest of any 8x32, owners say ED glass visibly tames fringing on birds in flight, and its fast focus wheel snaps between subjects. It focuses to 5.9 ft against the Nikon's 8.2 ft. Its trade-offs are a polycarbonate body, objective covers that fall off, a basic case, sharpness that gets close to premium European glass without matching it, a 4.0mm exit pupil that gives up last light to 42mm binoculars, and a thin US dealer network.
The Nikon is the reach option. Owners describe a bright, clear, color-accurate image, a 362 ft field that is wide for a 10x, tightly controlled fringing and easy controls. Its 4.2mm exit pupil is slightly larger. They also report more hand shake than an 8x, eye relief that is a bit tight for glasses, and veiling glare when viewing into bright light.
For travel, everyday birding, small hands and anyone in glasses, the Opticron is the better choice. The M7 10x42 is worth it for open-country birders and hunters who regularly need detail at distance.
Nikon Monarch M7 10x42
Best for open country, shorebirds, raptors and hunting, where 10x reach matters more than weight.
Opticron Traveller BGA ED 8x32
For glasses wearers, travelers and woodland birders, its wide view, long eye relief and pocketable size make it the easier carry.

What birders say
Nikon Monarch M7 10x42
- ✓Independent lab testing rated it an outstanding performer across nearly every metric - bright, clear, color-accurate viewing that resolved test-chart detail with exceptional clarity
- ✓The 362 ft field of view is genuinely wide for a 10x42 - you get real reach without the porthole feeling that plagues the Monarch M5 10x42's 293 ft window
- ✓Lighter and more compact than most 10x42 competitors, which testers specifically called out as an advantage for all-day carry
- ✓ED glass keeps chromatic aberration tightly controlled, with only faint edge fringing visible on extreme high-contrast targets
- ✓Testers praised how exceptionally easy adjustments are - smooth focus action and well-designed controls that make tracking subjects at 10x less fiddly
- ✓Great 8.2 ft close focus for a 10x binocular, keeping butterflies and near subjects in play
- ✓Locking diopter, oil- and water-repellent coatings, and nitrogen-purged waterproofing carry over from the 8x42 - a complete field package
- ✓Forum users comparing Nikon's 10x against the Vortex Viper HD tier repeatedly note the Nikon's wider view and lower price as deciding advantages
- ✗More handheld shake than the 8x42 - forum threads comparing the two consistently warn that the 10x magnifies every tremor, and some buyers end up wishing they'd taken the steadier view
- ✗Eye relief drops to around 16.5mm from the 8x42's 17.1mm - workable for many glasses wearers but noticeably less forgiving, and a common reason forums steer eyeglass users to the 8x
- ✗The 4.2mm exit pupil gives up low-light brightness versus the 8x42 - the image dims earlier at dusk, which matters for the dawn/dusk wildlife window
- ✗Inherits the M7 line's glare weakness - some owners report veiling haze when viewing against bright light
- ✗Lab testers noted it's not quite as bright as premium models a price tier up - it flirts with alpha performance but doesn't close the deal
- ✗Nikon's limited warranty remains a sore point next to Vortex's no-fault VIP coverage at the same price
- ✗At around $520 it competes with discounted Zeiss Conquest HD 10x42s that sometimes dip within a couple hundred dollars
- ✗The famous M7 wide-field advantage shrinks at 10x - testers rated the field of view merely average against the broader binocular market, even though it leads its 10x42 class
Opticron Traveller BGA ED 8x32
- ✓Exceptionally wide 429 ft (8.2°) field of view — among the widest of any 8x32 at any price, with a large sweet spot
- ✓Truly pocketable full-function binocular: under 460g (about one pound) and under 12cm long — reviewers note it slips into a jacket pocket without bulk
- ✓ED glass visibly tames color fringing, which reviewers specifically noticed on birds in flight against bright sky
- ✓Beat the Hawke Endurance ED 8x32 in a direct overcast low-light comparison for brightness and color reproduction
- ✓Smooth, precise focus wheel needing just over one full turn — quick to snap between subjects
- ✓Excellent 19mm eye relief, unusually generous for a compact and a genuine gift for eyeglass wearers
- ✓Small frame is 'far easier for small hands to grasp' — one reviewer's eight-year-old used it happily on a 1.5-mile bird walk
- ✓Repeatedly called a mind-changer on budget glass — a British Trust for Ornithology reviewer said it shifted his perspective on affordable optics, and a UK owner summed it up: 'simple design, extraordinary performer in a sleek package. A winner.'
- ✗Body is polycarbonate rather than the magnesium of its predecessor — a cost/weight trade reviewers accepted but noted as a step down
- ✗Rubber objective lens covers detach easily and are the most-cited accessory annoyance
- ✗The included soft case is basic — 'perfectly adequate' is the polite phrasing
- ✗Resolution gets 'surprisingly close' to Swarovski and Zeiss, per reviewers, but doesn't equal them — critical sharpness is a visible half-step behind true premium glass
- ✗The 4mm exit pupil concedes real brightness to 42mm binoculars in the last light of day
- ✗5.9 ft close focus is fine but trails butterfly-friendly rivals like the Kowa BD II line's 4.3 ft
- ✗Opticron's small US dealer and service footprint means less brand recognition, fewer places to try one, and thinner resale than Nikon or Vortex
- ✗US street pricing (around $450-550) is less of a bargain than its UK home-market price, pushing it against strong competition like the Nikon Monarch M7
