First Focal Plane vs Second Focal Plane: Which Scope to Choose (2026)

First Focal Plane vs Second Focal Plane: Which Scope to Choose (2026)

Two scopes are open in your cart with nearly identical magnification and price, and the only spec you cannot decode is "FFP" on one and "SFP" on the other. It sounds like fine print, but it changes how you aim. A first focal plane (FFP) reticle scales with magnification so your holdover and ranging marks stay accurate at every power, while a second focal plane (SFP) reticle stays one constant size and is simpler — and usually cheaper — for shooters who hold at a single magnification. Which one fits comes down to how you use the dial.

Key takeaways

  • The core difference is reticle behavior: an FFP reticle grows and shrinks with magnification; an SFP reticle stays the same visual size at every power.
  • FFP holdover and ranging marks are accurate at any magnification. SFP marks are only accurate at one magnification, usually the highest.
  • SFP scopes are often simpler, cheaper, and keep a bold reticle that is easy to see at low power; FFP shines for precision and long-range dialing and holding.
  • Accufire builds its EVRO-12 and ATRO-20 variable scopes on first focal plane, so subtensions stay true from 2.5× to 20×.

What "focal plane" actually refers to

A variable scope has two points along its optical path where a reticle can sit: ahead of the magnifying lenses (the first, or front, focal plane) or behind them (the second, or rear, focal plane). That placement decides one thing — whether the reticle is magnified along with the target image. Everything shooters argue about with FFP versus SFP flows from that single design choice; it does not affect glass quality, tracking, or how accurately the rifle shoots.

How a first focal plane reticle behaves

In an FFP scope the reticle is magnified together with the image, so it visibly grows as you zoom in and shrinks as you zoom out. The payoff is that every hash mark represents the same value at every power. If your reticle says a mark is 1 mil, that holdover is 1 mil whether you are on 2.5× or 20×, so you can range a target, hold for wind, or dial and confirm without doing mental math for your current magnification. That consistency is why precision and long-range shooters, including competitors in disciplines like the Precision Rifle Series, generally favor FFP.

How a second focal plane reticle behaves

In an SFP scope the reticle sits behind the magnifying lenses, so it stays exactly the same visual size no matter the power. The image zooms; the reticle does not. The advantage is a clean, bold aiming point that never gets thin or busy, and it stays easy to see at low magnification and in poor light. The catch is that the holdover and ranging subtensions are only calibrated at one magnification — almost always the scope's maximum — so if you hold over at a lower power, the marks no longer match their stated values.

FFP vs SFP — choosing by how you shoot

Pick based on whether you change magnification while aiming. If you range targets, hold over, or dial across a wide power band — practical and precision rifle work past a few hundred yards — FFP keeps your reticle honest at any setting. If most of your shots are taken at one magnification, or you want a bold reticle for a hunting rifle or a general-purpose build on a budget, SFP is simpler and easier on the wallet. Vortex, Leupold, Primary Arms, Nightforce, and Swampfox all sell both layouts, so the question is the discipline, not the brand. Accufire chose first focal plane for both of its variable scopes because their mil-based reticles are built for holding and ranging across the full 2.5×–20× range.

Feature First Focal Plane (FFP) Second Focal Plane (SFP)
Reticle size vs power Grows and shrinks with magnification Constant at every magnification
Holdover / ranging accuracy True at any power True only at one power (usually max)
Low-power reticle visibility Can look thin or small Stays bold and easy to see
Best suited to Long-range, dialing and holding, precision rifle Hunting, single-power holds, budget builds
Typical cost Often higher Often lower

Setup note: match the reticle to the turrets

Whichever plane you choose, make sure the reticle's units match your turret's units — a mil reticle with mil (0.1 mil) clicks, or an MOA reticle with MOA clicks — so a correction you see in the reticle dials cleanly on the turret. With an SFP scope, also remember which magnification its subtensions are calibrated to, and hold there if you are using the marks. None of this changes your zero; for the zeroing process itself, see our guide on how to zero a rifle scope.

Honest limitations and trade-offs

Neither layout is free of compromise. An FFP reticle can look uselessly thin at the bottom of its power range and busy at the top, and FFP scopes usually cost more to build. An SFP reticle is bolder and cheaper but quietly punishes you if you forget that its holdovers only hold at one magnification. There is no "better" plane in the abstract — only the one that matches your shooting. Accufire commits to FFP on its variable scopes because they are aimed at holding and ranging work; that is a deliberate fit for a use case, not a claim that FFP wins for everyone.

Frequently asked questions

What is the difference between first and second focal plane?

In a first focal plane scope the reticle grows and shrinks as you change magnification, so its holdover and ranging marks stay accurate at every power. In a second focal plane scope the reticle stays the same visual size at all magnifications, so its marks are only accurate at one set power, usually the highest.

Is FFP or SFP better for hunting?

Many hunters prefer second focal plane scopes because the reticle stays bold and easy to see at low magnification and most hunting shots are taken without ranging across powers. First focal plane is better if you regularly hold over or dial at varying magnifications.

Why do FFP reticles look small at low power?

Because a first focal plane reticle scales with magnification, it shrinks along with the image when you zoom out. At the lowest power it can appear thin or hard to see, which is one trade-off for keeping its subtensions accurate at every magnification.

Is the Accufire EVRO-12 first or second focal plane?

The Accufire EVRO-12 is a first focal plane scope with a 2.5 to 20 power range, so its mil-based holdovers and ranging marks stay true whether you are on 2.5 power or 20 power. The ATRO-20 is also first focal plane.

Does focal plane affect accuracy?

Focal plane does not change how accurately the rifle shoots; it changes whether your reticle's holdover marks are correct at a given magnification. With FFP they are correct at any power, while with SFP they are correct only at the calibrated power.

Focal plane is one piece of choosing a variable optic, alongside magnification range, reticle units, and mounting.
