What does first or second focal plane mean?
In a first focal plane scope, the Mil/MOA lines will be accurate and true throughout the entire magnification range. In a second focal plane scope, the subtensions will only be accurate on a specific magnification, typically the maximum magnification.
What does second focal plane mean?
In second focal plane riflescopes, the reticle stays the same size while the target grows and shrinks when you adjust the magnification. These reticles are ideal for low-light hunting situations and in scopes that don’t utilize hash marks for range estimation. Products (118)
What is the focal plane?
Definition of focal plane : a plane that is perpendicular to the axis of a lens or mirror and passes through the focus.
Why is FFP better than SFP?
The main difference between them is that an SFP reticle will appear to be the same size regardless of magnification. An FFP reticle appears to grow larger or smaller as the scope’s magnification is increased or decreased, respectively.
Is first focal plane better for long range?
Front Focal Plane is optimal. Scopes without FFP are a pain for long range, versus the quick dialing on turrets with it (with SFP you need to do all the BDC calculations, and only on full power).
What is first focal plane on a rifle scope?
A first focal plane (FFP) scope has a reticle that is placed towards the front of your riflescope’s erector tube assembly and your magnification lenses. Your reticle will appear to be the same size regardless of magnification power because it is placed in front of the magnification lens.
What is focal point and focal plane?
Figure 1: The front focal point is related to parallel rays on the back side (= output side). The focal planes are defined as the planes perpendicular to the optical axis which contain the focal points. The focal points and planes can be found for any optical system, except if it is an afocal optical system.
Why are first focal plane scopes more expensive?
Sometimes referred to as ‘front focal plane’, FFP scopes are usually more expensive by virtue of their more complicated construction, where the crosshair is placed in front of the lens group that determines the scope’s magnification.
What kind of binoculars does MeatEater use?
Viper 10 x 42 Viper HD Binoculars I spent my entire first year on the MeatEater crew glassing through the Viper 10x42s. From, long rainy days in the rainforests of Prince of Wales Island to endless hours searching for black bears in the mountains of Montana, the Vipers got the job done.
