FFP vs SFP scopes

[bearhunter]

If I got it backwards, I apologize.

first focal plane scopes

Second focal plane (SFP) scopes are designed with the reticle located behind the magnification lenses, keeping the reticle size constant regardless of the magnification level, making them ideal for hunting and general shooting applications.

Key Features of Second Focal Plane Scopes​

• Reticle Size: In SFP scopes, the reticle remains the same size at all magnifications. This means that as you zoom in or out, the target image changes size, but the reticle does not. This can make it easier to aim at various distances without the reticle becoming too large or small.
  
  2
• Ease of Use: Many shooters find SFP scopes easier to use, especially for hunting, as the reticle is consistently visible and does not change size. This is particularly beneficial in situations where quick target acquisition is necessary.
  
  2
• Hash Marks: One drawback is that the hash marks on the reticle only provide accurate measurements at full magnification. At lower magnifications, the values represented by these marks can vary, which may require some mental calculations for precise shooting.

Advantages of Second Focal Plane Scopes​

• Ideal for Hunting: SFP scopes are often preferred by hunters because they provide a steady aiming point that is easy to see against various backgrounds, making them suitable for quick shots at varying distances.
  
  2
• Cost-Effective: Generally, SFP scopes are less expensive than first focal plane scopes, making them a more budget-friendly option for many shooters.

Disadvantages of Second Focal Plane Scopes​

• Variable Measurements: The main limitation is that the reticle's hash marks are only accurate at one magnification level, which can complicate long-range shooting where precise adjustments are needed.
  
  2
• Less Versatile for Tactical Use: For tactical or competitive shooting, where quick adjustments for windage and elevation are crucial, first focal plane scopes may be more advantageous.

Conclusion​

When choosing a scope, consider your shooting style and needs. Second focal plane scopes are excellent for hunters and recreational shooters who prioritize ease of use and consistent reticle visibility. However, if you require precise measurements at varying distances, you might want to explore first focal plane options. Popular brands like Vortex and Sig Sauer offer a range of SFP scopes that cater to different preferences and budgets.

How do you guys see a FFP reticle below about 8x

Depends on the reticle design, I've found that reticles that use the donut of death (Bushnell LRHS) and german #4 reticle (Minox MR2 and MR5 in the 3-15x50 ZP) are visible at low magnification. The SHR-Mil Reticle in the Maven RS1.2 is also usable at lower magnification.

If you just want to shoot small groups at targets, SFP is fine. Just run it at the highest magnification when you want to use it to measure something.

If you are using your reticle to do precise holdovers and estimate wind drift at different magnifications, pony up for FFP.

FALSE – THE SCOPE IS SFP PER VORTEX WEBSITE - https://vortexoptics.com/optics/riflescopes/viper/viper-pst-gen-ii-5-25x50-ebr-4-moa.html

That is really surprising. They list a FFP version at Bass Pro:

The ones I have seen in person have been FFP.... maybe they have a version in each?

 

[Buck1950]

Gorby - Yep. Seems to be diff model #s - that's prob the SFP vs FFP - PST-5251 vs PST-5258.
So the OP is likely right . . . as is m1008 . . . and me, too.
Just shows you gotta read the fine print, esp if ordering online.

Ya, that would be a bummer getting out to the range to zero in, thinking you bought the FFP and having the SFP.

I have both first and second plane scopes.
First focal plane are pretty much what modern scopes are.
If you are going to use the stadia lines for ranging then the first focal plane is the go to. Usually way busier as far as the reticle is concerned.
I prefer the second focal plane personally.
Less busy and the reticle stays the same size as you dial up. You can range with them also but it takes practice.
I have used both scopes to shoot out to 2500 meters repeatedly.

2500?!

 

[proxemus]

I will only buy FFP MRAD scopes, i dont like my impact changing oh what ever power i choose.

 

[scott.y.]

2500?!

Yup. Scope is out of mils and round is out of gas.
Not sure what the angle of trajectory is when it hits the plate but it’s steep.
I made 6 of 8 shots at that distance.
5 mile crosswind to add to the fun.
I had the culminating point recorded in my book but I can’t find the old one right now.
It was way up there though.

where do you have space and distance to make shots like that?

 

[remington jim]

SFP - MOA - Is all that is used in F class shooting all over the world

 

[scott.y.]

The first time i tried it was at Rob Furlongs range in Alberta.
At home we have a lake a couple of miles behind our place on crown land.
Set up targets on the ice and shoot there.
It’s just for fun to see how far you can go.
Practice wind calls, do the math etc.
The round is way past it’s performance envelope. I suspect you could grab it with a catchers mitt at that range.

No..its SFP - OP states as much in post 1: "Just got a good deal on a vortex viper PST 5-25 x 50 but realize now it is a SFP reticle..."

I think the PST is available in both FFP and SFP

Not many competitive BR shooters using FFP scopes - most use SFP for a finer aim point


Not too many PRS shooters using SFP scopes - most use FFP so the reticle remains 'correct' as they dial down the magnification to INCREASE FIELD OF VIEW. Bigger FoV helps spot trace/hits/misses.

So really it's a matter of preference, and intended application.

I prefer SFP for lower magnification scopes like 3-9 and 2-10. If I'm using the holdover/wind marks, chances are I'll be at max magnification anyway.

I prefer FFP in 3-12 or 3-15, on up to about 5-25 or so. Reticle design is key, illumination can be helpful (especially in low light at low magnification - many hunters loath FFP because some designs can be weak when they need a scope the most)

SFP takes over again for me about 30x. Above that threshold (and depending on the design) FFP reticles can really get big as magnification increases. So in high mag target scopes (like a Vortex Golden Eagle) SFP for me.
