First Focal Plane VS Second Focal Plane Scopes - What's the Difference? - GUNS EXPLAINED

This video explains the fundamental differences between First Focal Plane (FFP) and Second Focal Plane (SFP) rifle scopes. FFP scopes magnify the reticle along with the image, making reticle subtensions consistent at all magnifications, ideal for precise long-range measurements. SFP scopes keep the reticle size constant while the image magnifies, which is often more cost-effective and suitable for quick target acquisition at lower magnifications where the reticle remains easily visible.

Quick Summary

First Focal Plane (FFP) scopes magnify the reticle along with the image, ensuring consistent subtensions for accurate long-range measurements at any magnification. Second Focal Plane (SFP) scopes keep the reticle size constant while the image magnifies, making them more affordable and suitable for quick target acquisition at lower power.

Frequently Asked Questions

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

The primary difference lies in where the reticle is positioned. In FFP scopes, the reticle magnifies with the image, keeping subtensions consistent. In SFP scopes, the reticle remains a fixed size while the image magnifies, making subtensions accurate only at specific magnifications.

When is a First Focal Plane (FFP) scope preferred over a Second Focal Plane (SFP) scope?

FFP scopes are generally preferred for long-range shooting where precise range estimation and holdovers are crucial. The reticle's consistent subtensions at all magnifications allow for accurate measurements regardless of zoom level.

What are the advantages of a Second Focal Plane (SFP) scope?

SFP scopes are typically less expensive and are advantageous for quick target acquisition at lower magnifications. The reticle remains easily visible and less obstructive when not needing precise measurements.

Does the reticle size change in an FFP scope when zooming?

Yes, in a First Focal Plane (FFP) scope, both the target image and the reticle magnify together. As you zoom in, the reticle appears larger, maintaining its proportional relationship to the target.
