Nikon Prostaff 7 vs Vortex Diamondback

What makes a riflescope superior to another? Is it their magnification, their build, or their unique functions? If you are stuck trying to figure out Nikon Prostaff 7 and the Vortex Diamondback, this review is for you.

Many riflescopes share features and benefits across brand names. This makes it difficult for novice shoppers to make the best selection for their needs, preferences, and expectations. 

I remember my first time walking into a gun and accessories store in search of my ideal riflescope. Having grown up watching and sometimes joining my older brother and his crew out on the buck hunting range, I believed I knew what I wanted.

He was a huge fan of the Vortex brand and I was sure I was going to pick out one from their categories but when I got to the store, I was baffled at the wide selection of amazing riflescopes I found. The Nikon brand particularly caught my eye so I found one that matched closely to my preferred riflescope specifications and I dug deep into their manufacturing and capacities.

Here is what I found.

Prostaff 7s has aBDC ballistic reticle with metallic crosshairs that are perfect for long-rangeshooting in any condition. They attract adequate light and they have a reflectivecoating on the air to surface glass lenses for maximum light transmission. Inbright light, their dark crosshairs contrast definitively which helps to zeroin on your target.

The reticle inVortex Diamondback has fully multi-coated lenses giving very crisp images andaccommodates Bullet Drop Compensation. The reticle has MOA sub-tensions tomatch the turret sub-tensions and corrections. It is fitted with a fast-focus eyepiecethat assists in reticle’s sharp focus.

Prostaff 7’s thickballistic crosshairs give the scope’s reticle an edge over the Diamondbackbecause they are vivid in bright light and defined in low light conditions.  


On the Prostaff 7, youare provided a slightly higher range of magnification and you have a tab thatcan be finger-tuned to adjust it. This tab is both convenient and practicalwhen out in the field. it also shortens your field of view making it easier totarget objects at a closer range.

A positive and tactical quick focus ring also ensures that the target is easily identified and tracked within the range. The magnification ring on theVortex Diamondback is a little shorter and has numbers printed on the back ofthe crown which makes it easy to see when you are behind the gun for quick andaccurate adjustments on the fly.

This power gives users a longer field of view and because it is a second focal plane scope, the changes in magnification do not affect the size of the scope’s reticle. This is perfect because then you don’t lose track of your target.

Operating magnificationis better on the Diamondback because it is a Second Focal Plane scope whichmeans that the focus aim doesn’t change with any adjustments to magnificationas is the case with the Prostaff 7 which is a First Focal Plane scope.


Prostaff 7 is fittedwith the Spring-Loaded Instant Zero-Reset Turrets that allow you to return tozero after sighting in your scope to your desired magnification. They arefinger-adjustable, click positively, and they turn smoothly. It has indicators withtwo alternatives in MOA click adjustments; 1 click equals ¼” at 100 yards and 1click equals 7mm at 100 meters.

The turrets on Diamondback are MOA with ¼ inch finger adjustments and they are easy to re-zero by pulling up the turret tab slide it over to zero and drop it back down. Some reset tensions don’t line up properly so you could lookout for that. There is no ZeroStop function but there is a revolution counter under the turrets which is handy.

Prostaff 7 outdoesthe Diamondback because they provide definitive Zero-Reset turrets that easilyand quickly get back to the zero settings even after repeatedly shooting yourrifle.

This is a second focal plane scope. It is made of standard aircraft-grade aluminum and it is water-proof, fog-proof, and shockproof. It has no issues shifting zero after firing. The magnification ring has numbers printed on the back of the crown which makes it easy to see when you are behind the gun and it is quite stiff even after months of use.

The glass quality has some mirage but gives bright images with no issues identifying targets. The reticle has some discoloration in the edges but very crisp within the image and accommodates bullet drop compensation. The reticle has MOA sub-tensions to match the turret sub-tensions and corrections.

It doesn’t have parallax adjustments or illumination and the eye-relief at 3.1 inches is quite low which causes some stress. To overcome that, you could mount it on a rail to help move it back a little bit for some comfort.


  • Printed magnification rings
  • Matching sub-tensions
  • Fast focus eyepiece


  • Short eye relief
  • No illumination

Because Nikon Prostaff 7s is a First Focal Plane scope, it is capable of handle long-range shooting with more accuracy and precision. Plus, their optics have better resolution images and adjustments are easier to do.

Vortex Diamondback is ideal for the shooters concerned about the weight of assembly because it is much lighter and shorter than the Prostaff 7. Although it has more light-gathering capacity, it fails to provide adequate eye-relief.
