The focal-plane mechanics and pros/cons below come from Grand View Outdoors' explainer, cross-checked against real current products: Vortex's own Diamondback line (SFP) versus Diamondback Tactical line (FFP), the Arken Outrider (SFP), and the Sig Sauer Whiskey5 (SFP), all linked in Sources.

What does first focal plane (FFP) mean?
In an FFP scope, the reticle is mounted in front of the erector/magnification lens system. That means the reticle image is magnified along with the target: at 3x it looks small, at 15x it looks large, exactly like the animal or paper target in the same field of view. The practical result is that any hash mark, dot, or holdover line etched into an FFP reticle represents the same real-world angular value at every magnification — a hash mark worth 2 MOA is worth 2 MOA whether you're on 4x or 20x.
What does second focal plane (SFP) mean?
In an SFP scope, the reticle sits behind the magnification lenses, closer to your eye, so it doesn't get magnified along with the image. The reticle stays a fixed visual size no matter what power you're on. That fixed size is exactly why SFP reticles read as bold and easy to see at low power in the woods — but it also means the hash marks' angular value changes with magnification, and is usually only correct at the top of the zoom range, where most manufacturers calibrate it.
| First focal plane (FFP) | Second focal plane (SFP) | |
|---|---|---|
| Reticle size | Scales with magnification | Constant at every magnification |
| Holdover marks accurate at | Every power setting | Usually one power (max) |
| Best at low power (2-4x) | Reticle can look thin/small | Bold and easy to see fast |
| Best at high power | Ideal for ranging & holdover | Fine, but marks may be off-value |
| Typical use | Long-range, PRS, predator, dialing hunters | General big-game hunting |
| Typical price vs. equivalent tier | Higher ($100-250+ more) | Lower |
Which is better for hunting?
For most Eastern and Midwestern whitetail hunting, dense-cover hog hunting, or any style where you pick one power and stay there most of the season, SFP is the better default. You get a bolder, easier-to-see reticle at low magnification for a quick shot in brush, and you save real money. The Arken Optics Outrider 2-12x42 I ran on a hog hunt is a good working example: second focal plane, a wide 2x low end for close cover, and priced well under an equivalent FFP scope.
FFP starts to earn its price once you're dialing magnification frequently and using the reticle itself to hold over or range at different distances — open-country mule deer, pronghorn, long-range coyote calling, or PRS-style shooting. If you're building a holdover chart for a rifle or a slug-tuned airgun and expect to shoot the same rifle at very different powers, FFP removes a real source of error. See building a holdover chart with mil-dots and MOA for how that math works in practice.
Do FFP scopes really cost more?
Yes, and you can see it inside a single product line rather than comparing different brands. Vortex's Diamondback riflescopes are second focal plane and run $339.99-$429.99 depending on model. The Diamondback Tactical line uses the same general build quality but switches to first focal plane, and runs $449.99-$649.99. That $100-250 gap for a comparable tier of glass is typical of the FFP premium across the market — Sig Sauer's SFP Whiskey5 3-15x52 lists at $1,429.99, and its FFP-reticle siblings in the same series price noticeably higher.
Good fit
- FFP: long-range or open-country hunters who dial power and hold over often
- FFP: shooters who range distance using reticle subtension marks
- SFP: close-to-medium hunters who set one power and leave it there
- SFP: anyone who wants a bolder, more visible reticle for a fraction of the price
Look elsewhere
- FFP if your budget is tight — you're paying for a feature many hunters never use
- SFP if you genuinely dial magnification for every shot and hold over at each one
Verdict
Default to SFP for standard hunting rifles and airguns used at one main power. Spend the extra $100-250+ on FFP only if you actually dial magnification and hold over with reticle marks at varying distances — otherwise you're paying for precision you won't use. Whichever focal plane you pick, make sure the reticle and turret units match; see MOA vs MIL next.

Once you've picked a focal plane, the next two decisions are magnification (see the scope magnification guide) and getting the scope mounted and leveled correctly, covered in how to mount and level a scope. For filming your hunts through whichever scope you choose, see how I run a scope-cam setup.
FAQ
What is the difference between FFP and SFP scopes?
In a first focal plane (FFP) scope, the reticle sits in front of the magnification lenses, so it grows and shrinks as you zoom, staying in true proportion to the target at every power. In a second focal plane (SFP) scope, the reticle sits behind the magnification lenses and stays the same visual size no matter what power you're on.
Which is better for hunting, FFP or SFP?
SFP is still the standard for general big-game hunting, because most hunters dial to one favorite power and leave it there, and a bold, constant-size reticle is easier to see fast in timber or brush. FFP earns its keep for hunters who dial magnification a lot and use holdover marks at varying ranges, like open-country or long-range predator hunters.
Do FFP scopes cost more than SFP scopes?
Usually, yes. Vortex's own Diamondback line shows the gap directly: the standard SFP Diamondback models run $339.99-$429.99, while the first focal plane Diamondback Tactical models run $449.99-$649.99 for a similar tier of glass. The added cost comes from the more complex reticle-etching and lens assembly FFP requires.
Can you use MOA or mil holdover marks on an SFP scope?
Only at one magnification, almost always the top of the zoom range. SFP reticle hash marks are cut to a fixed physical size, so their MOA or mil value only matches the manufacturer's spec at the power they calibrated it for. Dial down and the holdover marks read wrong.
Is a first focal plane reticle too small at low power?
That's the most common FFP complaint. Since the reticle shrinks with the image at low magnification, thin reticles can become hard to see fast at 2-4x, which matters for a quick shot in cover. Manufacturers offset this with a bolder center dot or thicker outer posts on hunting-focused FFP designs.
What focal plane is the Arken Outrider 2-12x42?
Second focal plane. It's a good real-world example of why SFP still dominates hunting optics at this price: a wide 2x low end for close cover, a reticle that stays a consistent, visible size, and a lower price than an equivalent FFP scope. See the full Arken Outrider 2-12x42 review.
Which is better for airgun hunters using holdover at different ranges?
FFP has a real edge if you hold over often at varying distances with slugs, since the holdover marks stay accurate at any power. Most dedicated hunting airgun scopes are still SFP, though, so plenty of airgun hunters build a holdover chart for one fixed power instead. See using mil-dots and MOA for air rifle holdover.
Does the reticle unit (MOA or mil) matter separately from focal plane?
Yes, they're two different choices. Focal plane decides whether the reticle scales with zoom; MOA vs mil decides what unit the hash marks and your turret clicks are measured in. You need to match reticle and turret units regardless of focal plane. See MOA vs MIL for the full breakdown.
