Is larger objective diameter always better in hunting scopes?

Objective Diameter and Field of View

When choosing a hunting scope, the field of view (FOV) is often more critical than the objective diameter. A wider FOV allows hunters to quickly locate targets over long distances without needing to constantly adjust their position. For example, a 2-7x scope with a 34mm objective diameter might offer a 115-foot FOV at 100 yards, while a 4-12x scope with a 50mm objective diameter might only offer a 70-foot FOV at the same distance. Consider the type of hunting you’ll be doing and the distance you typically shoot to determine the best objective diameter.

Objective Diameter and Glare Issues

While a larger objective diameter can admit more light, it can also create glare and distortion issues, particularly when shooting at high angles or in low-light conditions. This is because the larger objective diameter has a greater surface area, which can reflect and scatter light. To minimize these issues, look for scopes with a high-quality glass and a well-designed optical system, as well as features such as parallax adjustment and a reticle with a high-contrast design. A 40mm objective diameter may be a good compromise for most hunting applications.

Objective Diameter and Weight Considerations

Larger objective diameters also typically result in larger and heavier scopes, which can make them more difficult to carry and maneuver in the field. For example, a 1-inch tube scope with a 50mm objective diameter might weigh around 24 ounces, while a similar scope with a 30mm objective diameter might weigh around 14 ounces. Consider the weight and size of the scope in relation to the weight and size of your rifle and other gear, as well as your personal preference for a lightweight or high-magnification scope.
