The main trade-off
The 8x30 lists a wider field at the same magnification; the 8x42 lists longer eye relief. Neither specification predicts optical quality or personal fit.
Quick verdict
Both are 8x binoculars, but Nikon lists a wider field for the 8x30 (456 ft at 1,000 yd) and longer eye relief for the 8x42 (20.2 mm vs 15.4 mm). Choose by which specification answers your need, and test eyewear fit if that is decisive; these figures are not an optical performance test.
Choose Nikon PROSTAFF P3 8x42 Binocular if
- You prioritize the 8x42's 20.2 mm listed eye relief over the 8x30's wider field, while confirming actual fit if you wear glasses.
Choose Nikon PROSTAFF P3 8x30 Binocular if
- You prioritize the 8x30's wider listed field of view at the same 8x magnification and can accept its shorter listed eye relief.
When the recommendation changes
- If you wear glasses or need a specific eye position, try the binoculars with your own eyewear when possible; listed eye relief cannot guarantee your view or comfort.
- If a wider nominal field is not useful for your viewing situation, the 8x30's field-of-view specification may not outweigh the 8x42's longer listed eye relief.
The differences that matter
| Decision point | Nikon PROSTAFF P3 8x42 Binocular | Nikon PROSTAFF P3 8x30 Binocular |
|---|---|---|
| Field Of View | 8x magnification; 377 ft at 1,000 yd listed field of view[1] | 8x magnification; 456 ft at 1,000 yd listed field of view[2] |
What this changes: At the same stated magnification, the 8x30's listed field spans 79 more feet at 1,000 yd. That gives buyers who value nominal scene coverage a concrete comparison, but it does not show that moving subjects are easier to follow or that either view looks better.[1, 2] The better fit depends on your priorities | ||
| Eye Relief | 20.2 mm listed eye relief[1] | 15.4 mm listed eye relief[2] |
What this changes: The 8x42 lists 4.8 mm more eye relief. Treat that as a specification to compare, especially if eye position matters; it does not guarantee a full view or comfortable fit with any particular glasses.[1, 2] The better fit depends on your priorities | ||
Best for your routine
Prioritizing the wider manufacturer-listed field at 8x
Best fit: Nikon PROSTAFF P3 8x30 Binocular
Based on listed features, not comparative testing.
Nikon lists 456 ft at 1,000 yd for the 8x30 and 377 ft for the 8x42. Choose B if that wider stated field is the deciding feature; the specification does not establish easier tracking or better optical performance.
Prioritizing the longer manufacturer-listed eye relief
Best fit: Nikon PROSTAFF P3 8x42 Binocular
Based on listed features, not comparative testing.
Nikon lists 20.2 mm for the 8x42 and 15.4 mm for the 8x30. Choose A if the longer listed eye relief is more relevant to you, and check the actual view with your own glasses if you wear them; the value alone does not guarantee fit.

Questions shoppers ask
Does the longer listed eye relief guarantee that the 8x42 will work better with glasses?
No. Nikon lists 20.2 mm for the 8x42 and 15.4 mm for the 8x30, but those values cannot guarantee a full view or comfortable fit with your particular glasses. Try the view with your own eyewear if possible.
