Which one to buy
Same $230, but the Leupold BX-2 Alpine HD 8x42 brings more to the counter: ED glass and dielectric prism coatings, 18mm of eye relief against the Nikon's 15.7mm, a brighter 5.25mm exit pupil against 4.2mm, and a wider 394 ft field against 367 ft. Owners add that it ships with a chest harness case and that Leupold's lifetime guarantee is serviced in Oregon. The catch is that it is discontinued, so it may be hard to find new; confirm a seller has real stock before planning around it.
Owner impressions of the Alpine are good but measured. Reviewers call the view crisp and distortion-free, and it held up in sustained coastal rain. They also say it is only slightly sharper than Leupold's cheaper line, and that shoppers weighing it against the Prostaff P7 don't crown a clear winner. Its 13.5 ft close focus is unremarkable.
The Prostaff P7 10x42 is the lighter binocular at 21.2 oz against 24.3 oz, focuses down to 9.8 ft, and has the 10x reach. Owners call its center very sharp and like the slim hinge and locking diopter. Without ED glass, they see false color on bright edges, and they describe the eyecups as cheap and rattly.
So this is an 8x-versus-10x decision with a stock question attached. The Alpine's brighter, wider ED view is the better binocular for timber and low light, which makes it the pick if a new one turns up at $230; if not, the P7 is the current model and still a sound 10x.
Nikon Prostaff P7 10x42
For open-country hunters who want 10x reach in a 21.2 oz body from a model still in production.
Leupold BX-2 Alpine HD 8x42
Worth grabbing if you find one new at $230: brighter, wider and ED-equipped for timber and low light, though discontinued and getting scarce.

What birders say
Nikon Prostaff P7 10x42
- ✓Punches above its price on prism quality - phase-corrected, dielectric-coated prisms are features that used to require Monarch money, and reviewers say they eliminate the dull, low-contrast look of cheap roof prisms
- ✓Genuinely sharp center image - an astronomy-focused review called it 'very sharp' and noted it holds its own against classic porro-prism binoculars on the night sky
- ✓Surprisingly capable for stargazing - testers found no false-color halos around the Moon, Jupiter, or bright stars, with subtle star colors rendering well despite the lack of ED glass
- ✓Light and compact for a full-size 10x42 at about 21.2 ounces, with a slim bridge and manageable hinge that side-by-side testers preferred to the stiffer Vortex Diamondback HD
- ✓Close focus of 9.8 feet, the same as the Prostaff P3 - fine for distant birds, too long for butterflies
- ✓Locking diopter at a sub-$200 price, a feature usually reserved for more expensive glass
- ✓Named an editor's choice for best hunting binocular under $200, with reviewers praising the rugged, nitrogen-sealed, waterproof build
- ✓In three-way forum comparisons against the Vortex Diamondback HD, testers found sharpness essentially equal with the Nikon lighter and easier to handle
- ✗No ED glass - some false color shows up in daytime viewing on bright, high-contrast edges and specular reflections, which is exactly where the Monarch M5's ED elements pull ahead
- ✗Eyepiece build feels cheap - a side-by-side forum tester described the P7's eyecups as 'cheap and rattly' compared to the Monarch M5's
- ✗Edge-to-edge sharpness trails the Monarch M5 in direct comparisons - the ED-glass Monarch holds detail further into the field
- ✗Eye relief drops from a generous 20.2mm on the 8x42 to 15.7mm on this 10x42 - still workable for glasses but noticeably less forgiving
- ✗The 4.2mm exit pupil gives up meaningful low-light performance versus the 8x42, a real cost for a binocular marketed at hunters who glass at dawn and dusk
- ✗Glare handling is imperfect - reviewers of the Prostaff line have noted sun spots and flare artifacts when viewing toward direct sunlight
- ✗At 367 ft the field is close to the 8x42's 377 ft, but the 4.2mm exit pupil and 10x shake lose the easy feel that makes the 8x42 P7 such a simple recommendation
- ✗Sits in an awkward spot for upgraders - forum threads repeatedly conclude that another $70-90 gets you the Monarch M5's ED glass, leaving the P7 as the 'almost' choice
Leupold BX-2 Alpine HD 8x42
- ✓Adds ED-type glass, dielectric prism coatings, and a locking diopter over the entry McKenzie line for only about $60-130 more
- ✓Hands-on reviewers call the view crisp and distortion-free, with bright, accurate color from the BAK4 prism system
- ✓Verifiably sharper than the McKenzie in side-by-side viewing, per travel reviewers who tested Leupold's lines against each other
- ✓Real-world weather testing backs the waterproof/fogproof claims - one reviewer used it in Alaska's temperate-rainforest drizzle without issue
- ✓Ships with Leupold's GO Afield shoulder harness/case that clips to your body, an accessory step up from binoculars in this bracket
- ✓Oversized eyepieces and easy one-handed focus earn comfort praise for long wildlife-watching sessions
- ✓Light and packable for a full-size 42mm, with a durable rubber-armored magnesium-framed build
- ✓Leupold's lifetime guarantee with US-based Oregon service, repeatedly cited by owners as a reason to buy it over import-brand rivals
- ✗The optical gain over the much cheaper BX-1 McKenzie is real but marginal - reviewers say you need a side-by-side comparison to notice it
- ✗It sits in a brutally competitive bracket, and shoppers on forums cross-shopping the Vortex Diamondback HD and Nikon Prostaff P7 don't treat it as a runaway winner
- ✗Leupold's published specs for the line have shifted across versions, which has left forum users asking basic questions about its prism and construction details
- ✗Close focus is unremarkable, so it's not the pick for butterflies or feeder-distance viewing
- ✗Edge-of-field performance doesn't get the specific praise that its center sharpness does in hands-on reviews
- ✗The brand's budget lines are import-made, so you're paying partly for the Leupold name and warranty rather than US-made glass
- ✗Some owners report Leupold's budget-line diopters and clarity trail Vortex equivalents when compared directly
- ✗Leupold now sells it for about $230, which undercuts the Maven C.1, whose direct-to-consumer pricing still buys stronger glass
