Fundamentals of First and Second Focal Plane
In the realm of shooting and optics, the concept of the first and second focal plane can be pivotal in determining the performance, accuracy, and overall experience with a rifle scope. Understanding these fundamentals can help you make the right choices based on your preferences, requirements, and the specific shooting scenarios you are likely to encounter.
Understanding the Concept of Focal Plane
The focal plane in a rifle scope refers to the position of the reticle (crosshairs) relative to the magnification system. When you adjust the zoom on your scope, the location of the reticle in either the first or second focal plane determines how it changes, or does not change, in size. This distinction between the first and second focal plane significantly impacts how you align and aim at your target during shooting.
Defining the First Focal Plane
When a rifle scope has a reticle in the first focal plane (FFP), this means that the size of the reticle changes when you adjust the zoom. In other words, when you zoom in on a target, both the crosshairs of the reticle and the target itself get larger. This first focal plane characteristic allows the reticle sub tensions to be accurate at all magnification levels, making it an ideal choice for long-range shooting and changing conditions.
Defining the Second Focal Plane
On the other hand, in a second focal plane (SFP) rifle scope, when you zoom in, the target itself gets larger, but the reticle remains the same size. This feature allows the reticle to maintain its size regardless of the level of magnification, hence, providing a consistent view and easier aim understanding. However, a second focal plane scope’s hash marks for distance adjustment are only accurate at one specific magnification level, which can be a disadvantage in certain situations.
Features of First Focal Plane
The choice of the first focal plane comes with certain features that could prove beneficial, especially in specific shooting scenarios.
Reticle and Target Enlargement in Zoom
The most defining feature of first focal plane scopes is that the reticle grows or shrinks along with the target as you adjust the magnification. This characteristic can be advantageous in certain conditions, especially where accurate holdovers and lead calls are required, such as in long-range shooting.
Preference based on Survey Data
According to a survey, 42% of shooters preferred FFP, with 20% preferring SFP, and 14% didn’t have a preference. This shows a slightly higher preference amongst shooters for FFP, indicating that the features and benefits offered by FFP may resonate with a broader range of shooters in different shooting scenarios.
Examples of First Focal Plane Optics
There are numerous examples of first focal plane optics available in the market – offering various features and designs. Whether you’re a professional shooter or a hobbyist, the scope you select should be based on your specific requirements. Remember that choosing the right first focal plane scope can potentially improve your aim, accuracy, and overall shooting experience.
Characteristics of Second Focal Plane
Just like the first focal plane, the second focal plane also provides certain unique features and characteristics.
Target Zoom with Unchanged Reticle
A primary feature of second focal plane scopes is that the size of the reticle remains unchanged, regardless of the zoom level. This can be beneficial in certain situations where the shooter prefers the consistency of the reticle size.
Use of Hash Marks for Distance Adjustment
SFP scopes come with hash marks that assist in distance adjustment. However, remember that these markings are only correct at a specific level of magnification. Using these hash marks at different magnification levels can lead to overadjustment and errors in shooting accuracy.
Side Turret and Wind Adjustment
Another noteworthy feature of the second focal plane is that it often comes with a capped side turret many shooters prefer. This is especially useful when adjusting for wind elements, allowing shooters to use holdovers for wind adjustment instead of messing with the turret constantly.
The Impact of Magnification on Focal Plane
Magnification is a crucial factor that significantly impacts the use and functionality of both first and second focal planes.
Impact on First Focal Plane
In a first focal plane, magnification has a direct influence on the size of the reticle. As you increase the magnification, the reticle and the target both amplify in size. This means that the size of the crosshair grows, ensuring it maintains its spatial relationship with the target at all distances.
Impact on Second Focal Plane
For the second focal plane, the magnification only affects the perceived size of the target and does not influence the size of the reticle. This is why the hash marks within the second focal plane scopes only work accurately at a specific magnification level.
Comparing the Impact between both Focal Planes
When compared, the key difference lies in the behavior of the reticle. With FFP scopes, you have a consistent relationship between the reticle size and target regardless of magnification. With SFP scopes, the reticle size remains constant, potentially simplifying sight picture especially at lower magnifications, but requiring more awareness of the appropriate magnification setting for correct distance adjustments.
First Focal Plane Scopes for Long-Range Shooting
Long-range shooting scenarios typically see the most frequent use of first focal plane scopes. There are several reasons for this.
Advantages for Long-Range Shooting
The simultaneously adjusting crosshair size in FFP scopes can be advantageous in long-range shooting. Since the reticle subtensions remain accurate at any magnification, this allows the shooter to make precise estimations for holdover, windage, and lead calls.
Preference amongst Long-Range Shooters
Among long-range shooting communities, there’s a clear preference for first focal plane scopes. This is largely due to the advantage of consistent reticle subtensions at all magnifications, which simplifies ballistic compensation at varying distances.
How to Improve Accuracy with First Focal Plane Scopes
Improving shooting accuracy with first focal plane scopes comes down to understanding how the reticle size changes with the magnification and being comfortable adjusting for distance, windage, and lead on the fly. Regular practice, coupled with various shooting conditions, will enhance the overall accuracy.
Second Focal Plane Scopes for Short-Range Targets
Second focal plane scopes provide some advantages when it comes to short-range targets or other specific shooting scenarios.
Advantages for Short-Range Targets
The key benefit of second focal plane scopes in a short-range shooting scenario is the constant reticle size. This makes for an easier initial sight picture, especially on lower magnification, to quickly aim and shoot without the reticle obscuring the target.
Specific Magnification Level Accuracy
With SFP scopes, hash marks are only accurate at a particular magnification level, usually the maximum setting. Therefore, if you deal with mostly short-range targets and typically shoot on the same magnification level, the second focal plane can be an excellent choice.
Duplex Reticle as a Recommended Feature for Second Focal Plane
A duplex reticle, with its simple design and clean peripheral view, is often recommended for SFP scopes. This simplified reticle can minimize the chance of miscounting subtensions and can greatly improve the aim.
The Cost Implication of Focal Plane Choices
There’s no denying that your choice of focal plane also impacts the cost of the rifle scope.
Manufacturing Cost of First Focal Plane
FFP scopes are relatively more complex and expensive to produce – partly due to the position and etching process of the reticle. For these reasons, first focal plane scopes are generally higher on the price scale.
Comparative Cost of Second Focal Plane
Second focal plane scopes, in contrast, are generally less expensive to manufacture and, subsequently, to purchase. The reticle fabrication process is simpler, and the overall construction is less complicated, which contributes to lower production costs.
Choosing Between Cost and Performance
When choosing between cost and performance, it is essential to decide based on your specific needs and budget constraints. Both FFP and SFP scopes have their pros and cons, and the correct choice largely depends on your individual shooting requirements.
Understanding Reticle Illumination and Size Adjustment
Reticle illumination and size adjustment play a critical role in tailoring your shooting experience, depending on the choice of focal plane.
Role of Illumination in First Focal Plane Scopes
Illumination in FFP scopes can help mitigate issues with the changing reticle size. This feature can enhance visibility and offer a quick focus on the target, providing a better edge in low-light conditions and where precise aiming is crucial.
Reticle Size in Second Focal Plane Scopes
In SFP scopes, an important advantage is the constant reticle size, regardless of the magnification. This can be beneficial in managing the target view and ensuring consistent visual reference during aiming.
Benefits of Size Adjustment in Focal Planes
Size adjustment in both first and second focal planes allows the shooter to adjust the reticle’s appearance to their preference and changing conditions. This feature not only improves visibility and aim but also significantly enhances the overall shooting experience.
Impact of Focal Plane Choice on Shooting Scenario
Your choice of focal plane should largely depend on your specific shooting requirements and scenarios.
Scenarios Favoring First Focal Plane
FFP scopes are particularly advantageous in long-range shooting or dynamic situations where targets are at varying distances. In these scenarios, the aligned reticle and target enlargement can assist with compensating for ballistic effects.
Scenarios Favoring Second Focal Plane
In contrast, SFP scopes can provide an advantage in short to medium range shooting, or scenarios where the magnification level generally stays the same. The unchanging reticle size ensures a consistent aim and sight picture, regardless of your zoom.
Importance of Scenario in Choosing Focal Plane
Choosing the right focal plane based on your shooting scenario is crucial as it can significantly impact your performance, accuracy, and overall shooting experience. Understanding your requirements and choosing accordingly can go a long way in enhancing your shooting proficiency.
Conclusion: The Subjectivity of Focal Plane Preferences
In conclusion, it’s important to emphasize that preferences for focal plane choices can be subjective, largely based on individual shooting requirements and scenarios.
