Hey there, fellow rifle enthusiasts! As a supplier of centerfire rifle scopes, I get asked a ton about the difference between first - focal - plane (FFP) and second - focal - plane (SFP) scopes. So, let's dive right in and break it down.
What's a Focal Plane Anyway?
Before we get into the differences, let's understand what a focal plane is. In a rifle scope, the focal plane is a specific point inside the scope where the reticle is placed. This placement has a huge impact on how the reticle behaves as you adjust the magnification of the scope.
First - Focal - Plane (FFP) Scopes
In a first - focal - plane scope, the reticle is placed in front of the magnification lens system. This means that as you increase or decrease the magnification of the scope, the reticle changes size proportionally. For example, if you double the magnification, the reticle will also double in size.
One of the biggest advantages of FFP scopes is that the subtensions on the reticle (those little markings used for range estimation, hold - overs, and windage corrections) remain accurate at all magnification levels. Let's say you're using a reticle with mil - dots for range estimation. At any magnification, one mil - dot will always represent the same angular measurement in the real world. This is super handy for long - range shooting, where you might need to make quick and accurate adjustments based on the reticle's markings.
However, FFP scopes do have some drawbacks. They tend to be more expensive than SFP scopes because of the more complex internal design. Also, at low magnifications, the reticle can look quite thick and may obscure your target. This can be a problem, especially when you're shooting at close - range targets or in low - light conditions.
If you're into long - range shooting and need to make precise adjustments on the fly, a FFP scope might be the way to go. Check out our Long Range Centerfire Riflescopes for some great FFP options.
Second - Focal - Plane (SFP) Scopes
In a second - focal - plane scope, the reticle is placed behind the magnification lens system. This means that the reticle stays the same size regardless of the magnification setting. Whether you're at the lowest or highest magnification, the reticle looks exactly the same.
The main advantage of SFP scopes is their simplicity and cost - effectiveness. They're generally cheaper to manufacture, so you can get a high - quality SFP scope for a lower price compared to an FFP scope. Also, since the reticle doesn't change size, it's less likely to obscure your target at low magnifications. This makes SFP scopes great for hunting and close - to - medium - range shooting.
But here's the catch: the subtensions on the reticle are only accurate at one specific magnification level, usually the highest magnification. If you're using a reticle for range estimation or hold - overs, you need to remember to adjust your calculations based on the magnification you're using. For example, if the reticle's subtensions are calibrated for 10x magnification and you're shooting at 5x, you'll need to double your calculations.
If you're a hunter or someone who mostly shoots at closer ranges and wants a reliable and affordable scope, an SFP scope could be a perfect fit. We also offer Extended Eye Relief Rifle Scopes which are great for SFP setups, especially for those who prefer a bit more distance between their eye and the scope.
Which One Should You Choose?
The choice between FFP and SFP scopes really depends on your shooting needs. If you're a competitive long - range shooter who needs to make precise adjustments at any magnification, FFP is the way to go. But if you're a hunter or a casual shooter who doesn't need to worry about super - precise reticle measurements at all magnifications, an SFP scope will serve you well.
Another factor to consider is your budget. FFP scopes are generally more expensive, so if you're on a tight budget, an SFP scope might be a more practical choice.
Additional Considerations
There are a few other things to keep in mind when choosing between FFP and SFP scopes. For example, the type of reticle you prefer can also influence your decision. Some reticles work better with FFP scopes, while others are more suited for SFP scopes.
Also, think about the lighting conditions in which you'll be shooting. FFP scopes can be a bit more challenging to use in low - light conditions because of the thick reticle at low magnifications. SFP scopes, on the other hand, usually have a more consistent reticle appearance across different lighting conditions.
If you're into making quick adjustments on the side of the scope, we also have Side Focus Centerfire Rifle Scopes that can enhance your shooting experience, regardless of whether you choose an FFP or SFP scope.
