If you’re an avid shooter, you’ve probably heard of FFP and SFP scopes. But which one is better for you? Choosing the wrong scope can significantly impact your ability to shoot consistently. In this post, we’ll break down the differences between FFP vs SFP scopes and help you decide which one is right for your specific needs.
What’s The Difference: SFP vs FFP
Many shooters do not know the difference between SFP & FFP scopes. After all, you can’t even tell the difference just by looking at the scope. Here are the main differences:
- Second Focal Plane Scope (SFP) – The reticle is placed behind the magnification lens. The reticle stays the same size regardless of the magnification setting. This SFP is also called the rear focal plane.
- First Focal Plane Scope (FFP) – The reticle is placed at the front of the scope. The scope’s reticle size is correlated to the magnification.
Takeaway: FFP scopes have a reticle that changes with the scope’s magnification. SFP scopes have a reticle that stays the same size.
What Is SFP On A Rife Scope
SFP on a rifle scope stands for ‘second focal plane‘. The reticle is installed behind the magnifying lens. As you increase or decrease the scopes magnification, the actual reticle remains the exact same size.
Reticle stays the same size throughout the entire magnification range.
However, the reticle or crosshairs will appear to grow in size in relation to your target. This condition is referred to as scope subtension.
Pros & Cons – SFP Scope
Here are some of the pros to using a second focal plane scope.
- Reticle Visibility – The reticle maintains visibility at almost all power settings.
- Price – SFP models are typically cheaper than FFP scopes.
- Less Target Obstruction – When zoomed in to max magnification, SFP scopes obstruct less of the overall target.
Here are a few cons to using a second focal plane reticle.
- Changing Subtension – Modifying the zoom changes the subtension of the scope. This can be a problem if you need to make quick adjustments in the field.
- Poor Long Range Performance – SFP scopes tend to be less effective at long range than FFP scopes.
- Holdover Points – Usually only accurate at max power.
Can SFP Scopes Have Illuminated Reticles?
Yes, SFP scopes can have illuminated reticles. Illuminated reticles in second focal plane scopes offer several benefits, including enhanced visibility in poor lighting, fast target acquisition, and better accuracy. Shooters would want an illuminated SFP scope when engaging targets in dimly lit environments, such as afternoon hunting or dusk shooting range sessions.
What Is FFP On A Rife Scope
FFP on a rifle scope stands for ‘first focal plane’. Shocker right? On an FFP scope, the reticle is installed before the magnifying lens which is much closer to the shooter’s eye.
Reticle size changes in relation to the magnification setting.
This means that the reticle will get smaller as you zoom in and get larger as you zoom out. This technology creates a constant subtension. In other words, the reticle or crosshairs takes up the same amount of space relative to the target regardless of the magnification.
Pros & Cons – FFP Scope
Here are some of the main benefits of using a first focal plane reticle.
- Constant Subtension – The relationship between the size of the target and the size of the crosshair remains constant, regardless of magnification.
- Better In Low Light – FFP scopes tend to be better at light-gathering.
- Accurate From Long Range – The reticle is placed in the front of the scope making it better at high magnifications.
Here are some of the drawbacks of using first focal plane scopes.
- Low Power Visibility – FFP scopes have poor reticle visibility at low power.
- Expensive – On average, they cost more than SFP scopes.
- Target Obstruction – Reticles can obstruct small targets during max magnification.
Are FFP Scopes Good For Long Range Shooting?
Yes, FFP scopes are good for long-range shooting. First focal plane scopes have distinct advantages over SFP scopes at high magnification levels due to location of the reticles. In FFP scopes, the reticle size changes proportionally with the magnification adjustments, maintaining the same relationship with the target. This makes holdover and windage corrections much easier at any magnification. This is a main reason so many of the best scopes for hunting are FFP.
When Is An SFP Scope Best
Second focal plane scopes are best for two main situations:
- Lower magnification shooting
- Shooters on a budget
For hunters or avid shooters that mainly fire from lower magnification settings, SFP scopes are the best bet. They will obstruct less of your target and allow you to shoot quickly and accurately from a closer range. SFP scopes are also cheaper which makes them great for budget-conscious shooters.
When Is An FFP Scope Best
When comparing between first focal plane vs second focal plane scopes it depends on the shooter’s specific use case.
If you will be long-range shooting on high magnification, an FFP scope is the way to go. On average, the FFP scope will be more accurate across all distances because it can maintain constant subtension.
Choosing Between SFP vs FFP
There is no specific scope that works best for everyone. Your specific weapon and shooting conditions will determine whether or not you should choose an SFP or FFP scope.
If you’re a hunter, then you already know that choosing the correct scope is critical. Most hunters will shoot their game using low magnification scopes. For this reason, hunters primarily go with a second focal plane scope. A front focal plane scope will obstruct too much target and surrounding environment.

Takeaway: Second focal plane scope
2) Target Shooting
Depending on how far your targets are, both SFP & FFP scopes will work. In reality, there are not many ranges where you can take 800-yard shots. This means SFP scopes will be best for most people. Unless of course, you own a 100-acre ranch with your own personal shooting range! Check out The Best Scopes for Henry Big Boy 44 Magnum!
Takeaway: Second focal plane scope
3) Long Range Shooting
With FFP scopes, the reticle grows and shrinks along with your target. This is beneficial for long-range shooters because it allows you to make holdovers and windage adjustments on the fly. First focal plane scopes also offer greater clarity at higher magnifications, making them ideal for long-range shooting.

Takeaway: First focal plane scope
it depends on your intended use. If you plan to use your rifle for long-range shooting, then an FFP scope is a better option. The reason for this is that FFP scopes offer more consistent performance at different magnifications. On the other hand, if you’ll mostly be using your AR-15 for close-range shooting, then an SFP scope may be a better fit.
In reality, not many of us will be using our AR-15 for 10-12x magnification shots. Therefore, SFP scopes are the way to go for most people. Check out our post on the Best Scopes For AR-15 with Fixed Front Sights.
Takeaway: Both can work

The Bottom Line
Now you know the difference between FFP and SFP scopes. The truth is…there is no ‘best scope’. It really depends on your specific use case. If you are looking for an accurate scope to shoot at high magnification, go with FFP. Otherwise, consider trying an SFP scope for your rifle. Let us know which scope type you ended up choosing!
