First Focal Plane vs Second Focal Plane Rifle Scopes

Published on March 23, 2022
Duration: 12:32

This video explains the differences between First Focal Plane (FFP) and Second Focal Plane (SFP) rifle scopes. FFP reticles grow with magnification, keeping subtensions accurate at all powers, making them ideal for long-range shooting. SFP reticles remain a constant size, with subtensions only accurate at one magnification, often preferred for simpler, shorter-range hunting. FFP scopes are generally more expensive due to manufacturing complexity.

Quick Summary

First Focal Plane (FFP) rifle scopes have reticles that grow with magnification, ensuring subtensions remain accurate at all zoom levels, ideal for long-range shooting. Second Focal Plane (SFP) scopes have constant-size reticles, with subtensions only accurate at one magnification, often preferred for simpler, shorter-range applications.

Frequently Asked Questions

What is the main difference between First Focal Plane (FFP) and Second Focal Plane (SFP) rifle scopes?

In FFP scopes, the reticle scales with magnification, keeping subtensions accurate at all zoom levels. In SFP scopes, the reticle size remains constant, meaning subtensions are only accurate at one specific magnification, usually the highest.

When should I choose an FFP rifle scope?

FFP scopes are highly recommended for long-range shooting (over 300 yards) and competitive disciplines like PRS or NRL Hunter, where maintaining accurate holdover points across all magnifications is crucial.

When is an SFP rifle scope a better choice?

SFP scopes are often preferred for shorter-range hunting (under 150 yards) or situations where simplicity is valued. Their reticles are easier to see at low magnification, and precise holdovers at varying distances are less critical.

Why are FFP scopes generally more expensive than SFP scopes?

FFP scopes are more complex and costly to manufacture. The reticle must be placed further forward in the optical assembly, often requiring precise glass etching techniques rather than simpler wire reticles.
