Quick verdict
Start with the PROSTAFF P7 8x42 if longer listed eye relief is your priority. Choose the P7 8x30 if its fit works for you and you prefer a wider listed field at the same 8x magnification, with less weight to carry. Try your own glasses and eyecup setup before treating either as the right fit.

The differences that matter
| Decision point | Nikon PROSTAFF P7 8x42 | Nikon PROSTAFF P7 8x30 |
|---|---|---|
| Listed Field Of View | 377 ft at 1,000 yards; 8x magnification[1, 3] | 456 ft at 1,000 yards; 8x magnification[2, 3] |
What this changes: Choose the 8x30 if seeing a wider span at the same magnification matters most. The 8x42 gives up listed field width; the bigger objective does not mean a wider scene. These figures do not establish faster subject tracking.[1, 2, 3] Best fit: Nikon PROSTAFF P7 8x30 | ||
| Listed Eye Relief | 20.2 mm[1, 3] | 15.4 mm[2, 3] |
What this changes: The 8x42 is the first model to try if longer eye relief is your priority, especially with glasses. Eye relief describes eyepiece-to-eyepoint distance. The 8x30 trades that longer listed distance for its wider field. Try either with your own glasses and eyecup setting; neither number guarantees comfort or an unobstructed view.[1, 2, 3, 4] The better fit depends on your priorities | ||

- Eye relief is listed optical geometry, not a guarantee of glasses compatibility or comfort.
Questions shoppers ask
What should I check if I wear glasses?
Try the binoculars with the glasses you will actually use. Adjust the eyecups and check whether you can see the complete field without forcing an awkward position. The 8x42’s longer listed eye relief makes it a sensible starting point, but do not reject the 8x30 or assume the 8x42 fits from the numbers alone.
If both viewing positions work, which is easier to justify for carrying?
The 8x30 is listed at 485 g versus 590 g for the 8x42. That makes it the lower-weight option alongside its wider field; it does not establish which feels better in your hands.
