First Focal Plane vs Second Focal Plane Explained

When choosing a riflescope, one of the key design differences to understand is focal plane.

You may have seen the terms FFP (First Focal Plane) and SFP (Second Focal Plane) when comparing riflescopes. Both designs have their advantages, but they work differently as magnification changes.

Understanding those differences can help you choose a riflescope that better suits the way you shoot or hunt.

What Is First Focal Plane (FFP)?

In a First Focal Plane riflescope, the reticle is positioned in front of the magnification system.

As magnification increases or decreases, the reticle changes size along with the target image. At higher magnification, the reticle appears larger. At lower magnification, it appears smaller.

The main advantage of an FFP design is that the relationship between the reticle markings and the target remains consistent throughout the magnification range.

This means that holdover, windage, and ranging references remain valid at any magnification, provided the reticle is designed with those references.

FFP riflescopes are commonly used for:

• Long-range shooting

• Precision rifle shooting

• Competition shooting

• Situations where magnification may change frequently

For shooters who regularly use reticle markings to make elevation and windage corrections, an FFP reticle can provide greater flexibility across the entire magnification range.

What Is Second Focal Plane (SFP)?

In a Second Focal Plane riflescope, the reticle is positioned behind the magnification system.

Unlike an FFP reticle, the reticle appears to remain the same size as magnification changes. Whether you are at low or high magnification, the apparent size of the reticle stays relatively consistent.

Because the reticle does not scale with magnification, the angular spacing of reticle markings is typically accurate at one specified magnification.

This design can provide a more consistent aiming reference, particularly at lower magnification where an FFP reticle may appear smaller.

SFP riflescopes are commonly used for:

• Hunting

• General field shooting

• Short- to medium-range applications

• Shooters who prefer a consistent reticle appearance

For many hunting applications, a consistent reticle size can make aiming fast and intuitive when conditions or distances change quickly.

FFP vs SFP: What's the Difference?

Neither design is automatically better than the other. The right choice depends on how you plan to use the riflescope.

Example 1: EP-5 GENII 5-25x56 FFP

The EP-5 GENII 5-25x56 is a good example of why an FFP design is commonly used for precision and long-range shooting.

With a magnification range of 5-25x, shooters may adjust magnification depending on target distance, field of view, shooting position, or the level of precision required. Because the reticle is positioned in the First Focal Plane, it scales as magnification changes.

This means the reticle references remain proportional throughout the entire magnification range.

For example, imagine a shooter identifies a target and uses the reticle for both elevation and wind holds.

At 10x magnification, the shooter may use a specific hold point based on the reticle markings. If the shooter then increases magnification to 20x for a more precise view of the target, those same reticle references remain valid.

There is no need to return to a specific magnification before using the holdover or windage markings.

This becomes particularly useful with detailed precision reticles such as the VPR or TOR available on the EP-5 GENII. The reticle can be used for elevation and wind corrections while the shooter adjusts magnification according to the situation.

In this type of application, the FFP design gives the shooter greater flexibility. Magnification can be changed without changing the relationship between the reticle markings and the target.

The EP-5 GENII is therefore well suited to applications where shooters frequently use reticle-based holds, including long-range shooting and precision competition. Its FFP reticle is designed to keep subtensions and holdovers accurate at every magnification setting.

Example 2: OUTRIDER 2-12x42 SFP

The OUTRIDER 2-12x42 takes a different approach.

Designed around hunting and field use, the riflescope uses a Second Focal Plane reticle. Instead of changing size as magnification changes, the reticle maintains a consistent apparent size throughout the 2-12x magnification range.

Imagine a hunter moving through woodland or scanning open terrain.

At lower magnification, a wider field of view can make it easier to scan the environment and acquire a target. With an SFP design, the reticle maintains a consistent apparent size rather than becoming progressively smaller as magnification is reduced.

If the hunter then increases magnification for more precise aiming, the reticle still maintains the same apparent size.

This creates a consistent sight picture across the magnification range.

That does not mean SFP is less capable or less precise. It simply serves a different purpose.

For the OUTRIDER 2-12x42, the SFP design supports the type of field use the scope is built around: a clear and consistent aiming reference across changing distances and environments.

When using reticle-based subtensions or holdover references, however, it is important to remember that these references are calibrated for a specific magnification. The correct magnification should always be confirmed according to the reticle specifications.

Same Goal, Different Design

FFP and SFP are not competing technologies where one is automatically better than the other.

The difference comes down to how you use the riflescope.

A simple way to think about the difference is this:

FFP: The reticle scales with magnification, so reticle references remain proportional throughout the magnification range.

SFP: The reticle maintains a consistent apparent size, providing a stable sight picture as magnification changes.

So, Which One Is Right for You?

If you regularly use your reticle for holdovers and wind corrections while changing magnification, an FFP riflescope may be the better fit.

If you prefer a consistent reticle appearance and primarily use the scope for hunting or general field applications, an SFP design may better suit your needs.

The right choice depends less on whether FFP or SFP is "better" and more on how you actually use your riflescope.

Before choosing, consider:

• How often do you change magnification?

• Do you regularly use holdovers and windage references?

• What distances do you typically shoot?

• Do you prefer a detailed precision reticle or a consistent aiming point?

• What type of shooting or hunting do you do most often?

Understanding those answers can help you choose the focal plane design that best matches your application.
