FFP vs. SFP: What’s the Difference in Rifle Scopes?

If you're shopping for a rifle scope, you've probably seen the terms FFP (First Focal Plane) and SFP (Second Focal Plane). They can sound confusing, but understanding the difference can help you buy the right scope—and avoid wasting money on features you won’t need.

Let’s break it down in plain English.

What is the Focal Plane in a Scope?

The focal plane is just the spot inside your scope where the reticle (the crosshairs or markings) is placed.

If the reticle is in front of the zoom lenses, it’s called a First Focal Plane (FFP) scope.

If the reticle is behind the zoom lenses, it’s a Second Focal Plane (SFP) scope.

This small difference changes how the reticle looks when you zoom in or out.

How Does It Work?

FFP (First Focal Plane)

The reticle changes size as you zoom—gets bigger when you zoom in, smaller when you zoom out.

The spacing and markings on the reticle (called subtensions) always stay accurate, no matter the zoom level.

Perfect if you use the reticle for rangefinding, adjusting for wind, or making elevation calls.

Best for: Long-range shooting, tactical use, and situations where you zoom in and out a lot.

SFP (Second Focal Plane)

The reticle stays the same size, no matter how much you zoom.

Subtensions are only accurate at one zoom level (usually the highest one).

If you zoom out, the markings won’t line up with actual distances or bullet drop.

Best for: Hunting and casual shooting where you mostly use one zoom level.

How is This Different from Cameras or Telescopes?

In scopes, the focal plane affects how your reticle behaves while zooming.

In telescopes and cameras, there’s no reticle or aiming marks—so it’s just where the image is focused. That’s why the term “focal plane” means something much more important in rifle scopes.

Which One Should You Choose?

Choose FFP if:

You shoot at different distances.

You need precise holdovers or do long-range shooting.

You use your reticle to measure or adjust for bullet drop and wind.

Choose SFP if:

You shoot at short to mid-range, mostly using one zoom level.

You want a clear, always-visible reticle, especially at low zoom.

You prefer simplicity and speed.

FFP vs. SFP: Pros & Cons

FFP Pros:

Reticle always shows accurate markings at any zoom.

Great for advanced shooting and long-range precision.

FFP Cons:

Reticle can be hard to see at low zoom.

Usually more expensive.

SFP Pros:

Reticle stays large and easy to see.

Works well for fast shooting and hunting.

Generally more affordable.

SFP Cons:

Markings only work at one zoom level.

Can cause missed shots if you use the wrong magnification.

What About LPVOs, MPVOs, and HPVOs?

Let’s talk about scope types:

LPVO (Low Power Variable Optic – 1-4x, 1-6x, 1-10x)

SFP is better if you mainly shoot up close. The reticle stays big and easy to see.

FFP is better if you're shooting far (like 400+ yards) and need accurate reticle marks at any zoom.

MPVO (Mid Power Variable Optic – 2.5-20x, 3-15x)

Go with FFP. These scopes are made for flexible distances. You'll want accurate reticle marks at every zoom level.

HPVO (High Power Variable Optic – 5-25x, 6-36x)

FFP is the clear winner. At high power, accuracy and range estimation are key, and FFP does that best.

When Should You Choose FFP in an LPVO?

Use FFP in an LPVO if:

You shoot at longer ranges (300+ yards).

You use MIL/MOA marks for wind or elevation adjustments.

You don’t mind a smaller reticle at 1x zoom.

Final Thoughts: Which Is Right for You?

Choosing between FFP and SFP isn’t just about specs—it’s about how you shoot.

Here’s a simple cheat sheet:

FFP = Flexibility (accurate reticle at every zoom, great for long-range).

SFP = Simplicity (clear reticle that’s easy to see, great for fast or close-range shots).

LPVOs: Either one, depending on your use.

MPVOs & HPVOs: FFP is usually better.

Think about your shooting style and how much you use your reticle for distance and adjustments. That will guide you to the right choice.

If you're looking for a reliable and versatile scope, the Odin 1-6×28 FFP LPVO Rifle Scope is a great choice. Since it's a First Focal Plane (FFP) optic, the reticle scales with your zoom—meaning your holdovers and range marks stay accurate at every magnification level. This makes it perfect for both close-range and mid-range shooting. Whether you're on the range or in the field, the Odin 1-6×28 gives you the flexibility and precision serious shooters need—all in one compact, high-performance LPVO.
