Magnification, Field of View & Resolution

The riflescope also comes with a wide field of view that lets you see about 33 yards across at 100 yards when you are at 3x magnification and 13 yards across at 9x magnification. The wider the field of view you have the better off you will be when it comes to spotting and focusing on your target.

The multicoated lens system of the Leupold VX-I 3-9x40mm makes sure that you have a high-quality resolution. You get edge-to-edge sharpness and bright picture even when there is dim lighting.

Vortex scopes vs Leupold

Objective Lens Diameter

It is important to have a wide objective lens diameter so that a lot of light enters your riflescope to let you see bright images. The Leupold VX-I comes with an objective lens diameter of 40 millimeters which is sufficient for bright viewing from dawn to dusk.

Eye Relief & Precision Adjustments

The Leupold VX-I riflescope has a very leisurely eye relief of 4.2 inches at a magnification of 3x and an eye relief of 3.7 inches at a magnification of 9x. This is more than enough if you have to take long range shots from positions where you cannot easily get closer to the viewing lens. It is also a plus because you never have to worry about the rifle’s recoil taking off your brow.

The precision adjustments on the riflescope factor in windage and the elevation. The dials have micro-friction functionality. The click rate on the dials is an industry traditional 1 / 4 MOA which is very easy to set and return to zero.

Optical Coatings & Water/FogProof

The optical coatings on the Leupold VX-I have been made to make sure that you get only the brightest picture even when the sun is going down or just coming up. It has a standard lens system that is coated over and over again to make sure you get crisp, crystal clear sight pictures.

As with all Leupold riflescopes, the Leupold VX-I has that tough ruggedness with a nitrogen sealing that makes them waterproof and fog proof as well. You will not have to always be careful that moisture will get into your riflescope.

Optional Accessory Attachments

There are plenty of accessory attachments that one can get once they have purchased the Leupold VX-I 3-9x40mm. The best place to begin with the optional accessory attachments would be with the Leupold Std Medium Rings Matte 49901.

This is a set of rings that were constructed from machine steel for the mounting of Leupold riflescopes. They are available for many different rifles so you will not have a problem finding one that is for you.
