The buying question

Do you prefer the P3's wider listed field and lower listed weight, or the M5's closer listed focus distance?

Nikon lists a 377-ft field at 1,000 yd and 575 g weight for the P3 8x42; it lists 335 ft and 629.3 g for the M5 8x42. The M5's listed close-focus distance is 8.2 ft versus 9.8 ft for the P3.

Quick verdict

Choose Nikon PROSTAFF P3 8x42 (U.S. model 16776) if

  • You want the wider listed field (377 ft at 1,000 yd) and lower listed weight (575 g) among these two 8x42 models.
  • The P3's listed 9.8-ft close-focus distance works for your usual viewing subjects.

Choose Nikon MONARCH M5 8x42 (U.S. model 16767) if

  • The M5's listed 8.2-ft close-focus distance is more useful for the near subjects you observe.
  • You are comfortable carrying its listed 629.3 g weight in exchange for that closer minimum focus distance.
When to skip: You have ruled out full-size 8x42 binoculars; both models use that format.
When the recommendation changes
  • Both are listed as 8x42 central-focus binoculars, so the format and focusing system are shared. Nikon's published P3 field is 42 ft wider at 1,000 yd, while the M5 focuses 1.6 ft closer by the listed minimum distance.
  • The P3 is listed 54.3 g (1.9 oz) lighter. Treat that as a product-spec difference, not a promise that one binocular will feel more comfortable or perform better in the field.
  • If eyeglass fit is important, compare the listed eye-relief figures and try the eyecup position yourself when possible; the specifications cannot guarantee an individual full-field view.

The differences that matter

Viewing Fit And Adjustment Routine

Nikon PROSTAFF P3 8x42 (U.S. model 16776)

8x42, central focus; real field of view 7.2° / 377 ft at 1,000 yd; listed eye relief 20.2 mm; listed close-focus distance 9.8 ft.[1]

Nikon MONARCH M5 8x42 (U.S. model 16767)

8x42, central focus; real field of view 6.4° / 335 ft at 1,000 yd; listed eye relief 19.5 mm; listed close-focus distance 8.2 ft.[2]

What this changes: Nikon's stated figures give the P3 a 42-ft wider field at 1,000 yd and 0.7 mm more eye relief; the M5 is listed to focus 1.6 ft closer. These are feature-fit specifications, not evidence of better image quality, easier subject tracking, or guaranteed eyeglass fit.[1, 2]

The better fit depends on your priorities

Carry And Field Setup

Nikon PROSTAFF P3 8x42 (U.S. model 16776)

Nikon lists 575 g (20.3 oz).[1]

Nikon MONARCH M5 8x42 (U.S. model 16767)

Nikon lists 629.3 g (22.2 oz).[2]

What this changes: The listed weights differ by 54.3 g (1.9 oz), with the P3 lower on paper. This may matter when comparing what you plan to carry, but it does not establish comfort, overall packed size, or durability.[1, 2]

Limitations

  • This comparison uses Nikon-published product specifications; no hands-on, optical-quality, low-light, steadiness, or side-by-side performance test was conducted.
  • Field of view, eye relief and close-focus figures are specifications, not guarantees of individual fit or subject-tracking results. Try the binoculars if a precise fit is important.
  • Nikon's U.S. P3 page gives conflicting length figures in its comparison graphic (6.0 in) and technical specifications (5.9 in). Length is omitted from the carry comparison; weight figures are taken from each model's technical specifications.
  • Confirm the selected 8x42 model and included items on the seller's listing, since the comparison does not establish the contents of every retail offer.

Nikon lists 377 ft at 1,000 yd for the P3 8x42 and 335 ft for the M5 8x42, a 42-ft difference in the stated specifications. That does not predict which model will make a subject easier for you to find or track.

Which model is listed to focus closer?

The M5 8x42 is listed at 8.2 ft close focus; the P3 8x42 is listed at 9.8 ft. Treat these as manufacturer specifications, not a hands-on test.
