Head-to-head
Vortex Bantam HD 6.5x32 vs Nikon Prostaff P3 8x30: Bantam fits narrower eye spacing, Nikon reaches a nine-foot feeder
The short answer
Choose the Bantam HD 6.5x32 if a measured user needs 51–55 mm eye spacing and the subjects stay at least 12 ft away. Choose the Prostaff P3 8x30 for a 9 ft feeder, a wider field or a user above 69 mm. Neither covers every shared-household combination.
Before you choose
The reasoning and the trade-offs
An age label cannot replace two eye-spacing measurements
Bantam reaches narrower spacing, while P3 reaches wider spacing. A pair of users measuring 53 and 71 mm cannot share either within the published intervals.
What this is based on
Bantam adjusts 51–69 mm and P3 56–72 mm. Their shared interval is 56–69 mm. Age and face shape are not inferred from these numbers.

What matters in practice
The differences that matter
An age label cannot replace two eye-spacing measurements
Bantam reaches narrower spacing, while P3 reaches wider spacing. A pair of users measuring 53 and 71 mm cannot share either within the published intervals.
How we reached this conclusion
Bantam adjusts 51–69 mm and P3 56–72 mm. Their shared interval is 56–69 mm. Age and face shape are not inferred from these numbers.
The close feeder can rule out the narrow-fit option
A 9 ft feeder fits P3 but is too close for Bantam. If a 53 mm user must watch that feeder, neither of these two purchases resolves the combined job.
How we reached this conclusion
Close focus is 12 and 8.2 ft. Combine those limits with Bantam's 51 mm minimum and P3's 56 mm minimum eye spacing.
Lower magnification does not produce the wider field here
P3 offers 8x magnification and a 456 ft field against Bantam's 6.5x and 400 ft. Bantam counters with lower weight and longer eye relief, which may matter more for the actual user.
How we reached this conclusion
P3 has 23.1% more magnification and 14% more field width. Weights are 14.4 and 16.75 oz. Eye relief is 18.7 and 15.4 mm.
Choice A
Vortex, Bantam HD 6.5x32

Checked facts
- Eye-spacing fit: 51–69 mm
- Closest focus: 12 ft

Choice B

Recommendation switch
The decision flips if...
A user measures 53 mm and wildlife stays beyond 12 ft
Choose Vortex Bantam HD 6.5x32. Bantam meets the combined eye-fit and focus requirements.
All users fit P3 and the feeder is at 9 ft
Choose Nikon Prostaff P3 8x30. The nearer focus becomes the deciding capability.
You need both 53 mm eye fit and a 9 ft feeder
Choose neither. Each model misses one of the two requirements.
What matters in practice
Before you choose
What this comparison cannot tell you
- These are manufacturer specifications and reproducible comparisons, not hands-on sharpness, steadiness or brightness tests.
- Exit pupil is objective diameter divided by magnification. It does not establish measured light transmission or a low-light winner.
- Published eye relief and body dimensions cannot guarantee personal glasses fit or packed-case clearance.
