As a seasoned hunter and outdoor writer, I’ve spent countless hours behind the scope, and one question consistently arises: first focal plane scope or second? It’s a debate that can feel overwhelming, especially for those newer to precision shooting. Understanding the differences between first focal plane scopes (FFP) and second focal plane (SFP) scopes is crucial for accurate shot placement, particularly at varying distances. This guide will break down everything you need to know, helping you choose the right optic for your hunting style and needs. We’ll cover first focal plane scopes vs second, the pros and cons of each, and when one might be preferable over the other.
What is Focal Plane and Why Does it Matter?
Before diving into the specifics of FFP and SFP, let's define focal plane. The focal plane is where the reticle image is focused. Think of it like the lens of a camera – the focal plane is where the image is sharpest. In a riflescope, the reticle can be located in either the first or second focal plane. This positioning dramatically affects how the reticle appears relative to the magnified image.
Understanding the First Focal Plane (FFP)
In a first focal plane rifle scope, the reticle is located in front of the magnification lens. This means the reticle magnifies along with the target. What you see through the scope at 10x magnification will have the same reticle size and holdover values as it does at 4x, only everything will be larger. This is a key advantage for hunters who frequently adjust magnification. The reticle markings remain consistent regardless of the zoom level, allowing for accurate ranging and holdovers at any distance. This consistency is why many long-range shooters prefer ffp hunting scopes.
Understanding the Second Focal Plane (SFP)
With a second focal plane scope, the reticle is located behind the magnification lens. The reticle size remains constant, while the target image changes with magnification. This means the reticle appears the same size at 4x as it does at 20x, but the target will appear much larger at 20x. SFP scopes are often simpler and less expensive to manufacture, making them a popular choice for general hunting applications where shots are typically taken at closer ranges. However, the holdover values on the reticle will only be accurate at a specific magnification – usually the highest magnification setting.
First Focal Plane Scopes vs. Second Focal Plane: A Detailed Comparison
Let’s break down the key differences between first focal plane vs second focal plane scopes in a more structured way. Here's a table summarizing the pros and cons:
| Feature | First Focal Plane (FFP) | Second Focal Plane (SFP) |
|---|---|---|
| Reticle Magnification | Magnifies with the target | Remains constant |
| Holdover Accuracy | Accurate at all magnifications | Accurate only at a specific magnification (usually max) |
| Reticle Complexity | Can appear smaller at lower magnifications | Generally clearer at lower magnifications |
| Cost | Generally more expensive | Generally less expensive |
| Ideal For | Long-range shooting, variable magnification hunting | Shorter-range hunting, fixed magnification use |
When to Choose a First Focal Plane Scope
I recommend a first focal plane rifle scope in several scenarios. If you’re a hunter who frequently engages targets at varying distances, an FFP scope is a game-changer. Here’s when it shines:
- Long-Range Hunting: For shots beyond 300 yards, the ability to have accurate holdovers at any magnification is invaluable. (National Park Service Hunting Safety)
- Variable Magnification: If your scope has a significant magnification range (e.g., 4-16x, 6-24x), an FFP scope ensures your reticle remains consistent as you zoom in and out.
- Using BDC (Bullet Drop Compensation) Reticles: BDC reticles rely on accurate holdovers. An FFP scope ensures those holdovers are correct at all magnification levels.
- MRAD or MIL Reticles: Milliradian (MRAD) and Military (MIL) reticles are commonly used for precise long-range shooting. These reticles require a first focal plane to function correctly.
When to Choose a Second Focal Plane Scope
While FFP scopes are gaining popularity, SFP scopes still have their place. They are a solid choice for hunters who primarily shoot at closer ranges or prefer a simpler setup. Consider an SFP scope if:
- Shorter-Range Hunting: If most of your shots are under 200 yards, the inaccuracies of SFP holdovers at lower magnifications are less significant.
- Fixed Magnification: If you prefer a scope with a fixed magnification (e.g., 4x, 6x), the focal plane becomes less critical.
- Simplicity and Cost: SFP scopes are generally more affordable and easier to understand for beginners.
- Clarity at Lower Magnifications: Some hunters prefer the clearer reticle view of an SFP scope at lower magnifications.
The Debate: 1st Focal vs 2nd Focal for Hunting
The first vs second focal plane debate often comes down to personal preference and hunting style. I’ve seen experienced hunters successfully use both types of scopes. However, the trend is leaning towards FFP, especially as more hunters embrace long-range shooting techniques. The ability to trust your reticle at any magnification provides a significant advantage in the field.

What About 2nd Focal Plane Scopes for Long Range?
While not ideal, second focal plane scopes for long range can be used, but you must be diligent about knowing the magnification at which the reticle is accurate. You’ll need to zero your rifle at that specific magnification and consistently use that zoom level for accurate holdovers. This adds a layer of complexity and potential for error that many long-range shooters prefer to avoid.
What is First and Second Focal Plane in Simple Terms?
Let’s simplify things. Imagine you’re looking at a map. A first focal plane scope is like a map that zooms in on both the terrain and the scale. The scale remains accurate no matter how much you zoom. A second focal plane scope is like a map where the terrain zooms, but the scale stays the same size. The scale is only accurate at a specific zoom level.
Choosing the Right Scope: Beyond Focal Plane
The focal plane is just one factor to consider when choosing a riflescope. Other important considerations include:
- Magnification: Select a magnification range appropriate for your typical hunting distances.
- Objective Lens Size: A larger objective lens gathers more light, improving visibility in low-light conditions.
- Reticle Type: Choose a reticle that suits your hunting style and target acquisition preferences.
- Turret Adjustments: Consider the type of turrets (e.g., click adjustments, zero stop) and their adjustment increments.
- Glass Quality: High-quality glass provides a clearer, brighter image. (REI Expert Advice on Riflescopes)
Final Thoughts on First Focal Plane vs. Second
Ultimately, the best first or second focal plane scope depends on your individual needs and preferences. If you’re serious about long-range shooting or frequently hunt at varying distances, a first focal.plane vs second comparison strongly favors the FFP option. The consistent reticle size and accurate holdovers at all magnifications provide a significant advantage. However, if you primarily hunt at closer ranges and prioritize simplicity and cost, an SFP scope can be a perfectly viable choice. Do your research, consider your hunting style, and choose the optic that will help you make ethical and accurate shots in the field. And remember, practice is key – no matter which scope you choose!
