Q: What are SFP and FFP reticles in scopes?

A: SFP (Second Focal Plane) reticles are located behind the objective lens in the second focal plane, while FFP (First Focal Plane) reticles are situated in front of the objective lens in the first focal plane.

Q: How do the reticle sizes compare relative to the target in SFP and FFP scopes?

A: In SFP scopes, the reticle size remains constant regardless of magnification, causing the target image to appear smaller at higher magnifications. In contrast, in FFP scopes, both the reticle and the target image adjust in size together with changes in magnification, maintaining the same aiming point throughout.

Q: What is the impact of focal plane location on parallax?

A: SFP scopes can suffer from parallax errors at lower magnifications since the reticle is not in the focal plane of the target image. FFP scopes avoid this issue as the reticle and the target image are always aligned at the same focal distance, which eliminates parallax at all magnifications.

Q: Which type of reticle is generally more expensive?

A: FFP scopes tend to be more expensive than SFP scopes. This price difference stems from the more complex optical design required to place the reticle in the first focal plane.

Q: Which applications are best suited for FFP and SFP scopes?

A: FFP scopes are ideal for long-range precision shooting, where consistent holdover points are critical at different magnifications. SFP scopes are better suited for hunting and tactical scenarios where quick target acquisition is prioritized.

Summary: FFP scopes provide a consistent sight picture and are free from parallax at all levels of magnification, making them suitable for precision shooting. SFP scopes, while simpler and typically less expensive, may encounter issues with parallax and reticle size changes at higher magnifications, making them more aligned with general hunting and tactical needs.
