Nikon’s Prostaff series has long been a trusted choice for outdoor enthusiasts seeking high-quality optics at an affordable price. The Prostaff P3 and P7 are two popular models in this lineup, offering a range of features designed to enhance your adventures. In this comprehensive comparison, we’ll delve into the key differences between these two binoculars to help you make an informed decision.
Magnification and Objective Lens Size
The Prostaff P3 offers 8x magnification with a 32mm objective lens, while the Prostaff P7 boasts 10x magnification with a 42mm objective lens. Higher magnification provides a closer view of distant objects, while a larger objective lens allows for more light transmission, resulting in brighter images in low-light conditions.
Field of View and Close Focus
The field of view (FOV) refers to the width of the area you can see through the binoculars. The Prostaff P3 has a FOV of 419 feet at 1,000 yards, while the Prostaff P7 offers a slightly wider FOV of 350 feet at 1,000 yards. The close focus distance, which indicates the minimum distance at which the binoculars can focus, is 11.5 feet for both models.
Optical Quality
Both the Prostaff P3 and P7 feature fully multi-coated lenses and prisms, which minimize light loss and enhance image brightness and clarity. The Prostaff P7, however, incorporates Nikon‘s ED (Extra-low Dispersion) glass, which further reduces chromatic aberration, resulting in sharper images with minimized color fringing.
Body and Build
The Prostaff P3 is slightly smaller and lighter than the Prostaff P7, weighing 18.7 ounces compared to 27.5 ounces. Both models feature a rugged rubber-armored body that provides durability and a secure grip. They are also waterproof and fogproof, making them suitable for use in all weather conditions.
Eye Relief and Diopter Adjustment
Eye relief refers to the distance between the eyepiece lens and the user’s eye. The Prostaff P3 offers 15mm of eye relief, while the Prostaff P7 has 16.2mm. This is an important consideration for eyeglass wearers, as it determines how close they can get to the binoculars without seeing a black ring around the edges. Both models also feature a diopter adjustment ring, allowing you to correct for any differences in vision between your eyes.
Accessories and Warranty
Both the Prostaff P3 and P7 come with a neck strap, lens caps, and a carrying case. The Prostaff P7 additionally includes a rain guard to protect the binoculars from rain and snow. Both models are backed by Nikon’s generous 25-year warranty.
Which Binocular is Right for You?
The choice between the Nikon Prostaff P3 and P7 depends on your specific needs and preferences. If you prioritize portability and a wider field of view, the Prostaff P3 is a great option. For enhanced magnification, brighter images in low light, and sharper optical quality, the Prostaff P7 is the better choice.
