As magnification changes, the reticle's apparent size changes with the image.
This configuration can be useful for certain reticles containing angular reference markings.
19. SFP Hunting Scope
SFP means Second Focal Plane.
The reticle is located in the second focal plane.
Its apparent visual size generally remains consistent when magnification changes.
This can make the reticle easier to recognize at different magnification settings.
20. FFP vs. SFP
| Feature | FFP Scope | SFP Scope |
|---|---|---|
| Reticle Location | First Focal Plane | Second Focal Plane |
| Reticle Appearance | Changes with magnification | Generally consistent |
| Low Power | Finer reticle appearance | Consistent reticle size |
