Learn what a first focal plane (FFP) scope is, how it differs from SFP, and when to choose FFP for shooting at varying distances.
Quick Answer
A first focal plane (FFP) scope keeps the reticle scale proportionally with the magnification, so your holdover marks remain accurate at every power. Choose FFP if you shoot at varying distances and need to use the reticle for ranging or holdovers.
Why FFP Matters for Long-Range Shooting
When you're shooting at different distances, the last thing you want is to recalculate your holdover because you changed magnification. With an FFP scope, the reticle grows and shrinks with the image, so the subtensions (the marks on the reticle) always correspond to the same angular measurement. That means your holdover for a 600-yard shot stays correct whether you're at 10x or 25x.
This is especially useful for tactical or competition shooting where you might need to quickly engage targets at unknown distances. You can use the reticle to range targets and apply holdovers without dialing or doing mental math on the fly.
FFP vs SFP: The Trade-Off
The main alternative is a second focal plane (SFP) scope, where the reticle stays the same size regardless of magnification. SFP scopes are often cheaper and have thinner reticles at high power, which some shooters prefer for precise aiming. But the holdover marks are only accurate at one magnification (usually the highest), so you must remember to stay on that power or compute corrections.
FFP scopes are generally more expensive and the reticle may appear thicker at high magnification, which can obscure small targets. However, for dynamic shooting where you change magnification often, FFP is the practical choice.
FFP Scope FAQ
- What does first focal plane mean?
- In a first focal plane scope, the reticle is positioned in front of the magnifying lens group, so it scales up and down with the image as you change magnification. This keeps the reticle's subtensions true at all power settings.
- Is FFP better than SFP?
- It depends on your use. FFP is better for shooters who need accurate holdovers at multiple magnifications, like tactical or competition shooters. SFP is often sufficient for hunters who shoot at a fixed distance and prefer a thinner reticle at high power. Think about how often you change magnification during a shot.
- How do I use an FFP scope for holdovers?
- With an FFP scope, you can use the reticle's hash marks or dots to hold over for bullet drop at any magnification. The marks correspond to angular measurements (like MILs or MOA), so they remain correct regardless of zoom. Practice with your specific load to learn the holdover values. Confirm your reticle's unit (MIL or MOA) and zero your scope accordingly.
