The Schneider 68-017138 138mm MPTV ND 1.2 polarizer filter is a high-quality optical accessory designed for photographers and videographers who prioritize image quality and versatility. Below is a detailed breakdown of its pros and cons, followed by a conclusion and recommendation.

---

1. **High-Quality Construction and Optics**

The Schneider Kreuznach brand is well-regarded for its precision engineering and superior optical coatings. This filter is built to high standards, with minimal flare and ghosting, ensuring sharp, clear images even in bright conditions. The multi-layer anti-reflective coating helps maintain image clarity and reduces lens aberrations.

2. **Versatile Functionality**

The filter combines two useful features in one: a **neutral density (ND) stop of 1.2** and a **polarizer**. The ND 1.2 allows for slower shutter speeds in bright light without overexposing the image, which is particularly useful for long exposures, motion blur effects, or shallow depth-of-field in daylight. The polarizer component helps reduce glare, reflections, and haze, enhancing contrast and saturation in landscapes, architecture, and other scenes where reflections are problematic.

3. **MPTV Threading**

- **Fixed Position:** The filter can be set to a specific ND or polarizer strength and locked in place.

- **Variable ND/Polarizer:** The filter can be adjusted on the fly to change the ND density or polarizer effect, which is convenient for quick adjustments during shooting. This is especially useful for videographers who need flexibility without changing filters mid-shoot.

4. **Durability and Weather Sealing**

Schneider filters are typically built to withstand harsh conditions. The 138mm size is robust, and the weather-sealed design protects against moisture and dust, making it suitable for outdoor use in various environments.

5. **Compatibility with Schneider s Filter System**

If you already own other Schneider filters or accessories, this one will integrate seamlessly into your existing setup. Schneider s filters are known for their consistent quality and compatibility with each other.

6. **Reduces Lens Flare**

The polarizer component can significantly reduce lens flare caused by bright light sources like the sun, which helps maintain image quality in challenging lighting conditions.

7. **Professional-Grade Performance**

This filter is favored by professionals and enthusiasts alike for its ability to deliver consistent, high-quality results. It s particularly useful for photographers who shoot in dynamic lighting conditions where control over exposure and reflections is critical.

---

1. **High Cost**

The Schneider 68-017138 is a premium product, and its price reflects that. For photographers on a tight budget or those who don t frequently need the combined functionality of an ND and polarizer, this filter may be overkill. A separate ND filter and polarizer might be more cost-effective if used individually.

2. **Bulkiness and Weight**

The 138mm size is larger and heavier than smaller filters (e.g., 77mm or 82mm). If you frequently switch between different lens sizes or travel light, carrying a 138mm filter may be cumbersome. However, if you primarily use larger lenses (e.g., 85mm ), this is less of an issue.

3. **Learning Curve for Variable Use**

While the MPTV design is convenient, it may take some practice to adjust the filter quickly and accurately during shooting, especially in fast-paced situations like videography. Beginners might find it easier to use fixed ND and polarizer filters until they become comfortable with the variable system.

4. **Limited ND Strength**

The ND 1.2 stop is relatively mild compared to stronger ND filters (e.g., ND 3.0 or ND 10). If you frequently shoot in extremely bright conditions (e.g., midday sun), you might need to stack this filter with a stronger ND or use it in combination with other filters. However, for most daylight scenarios, ND 1.2 is sufficient.

5. **Potential for Polarizer Overuse**

Polarizers are most effective when used selectively. Overusing them can lead to a loss of detail in the sky or other areas where the polarizer is applied too aggressively. The variable nature of this filter requires an understanding of when and how to use the polarizer effectively to avoid unintended effects.

6. **Not Ideal for All Genres**

While this filter is excellent for landscapes, architecture, and videography, it may not be as useful for genres like portrait photography or macro, where ND filters are less critical, and polarizers can sometimes be avoided.

---

The Schneider 68-017138 138mm MPTV ND 1.2 polarizer filter is a powerful tool for photographers and videographers who need a versatile, high-quality solution for managing exposure and reflections in bright conditions. Its combination of ND and polarizer functions in a single, adjustable unit makes it highly practical for those who shoot in variable lighting or require quick adjustments. The premium build quality and optical performance justify the cost for professionals and serious enthusiasts who prioritize image quality and convenience.

However, the high price, bulkiness, and potential learning curve for variable use may deter budget-conscious users or those who don t frequently need both ND and polarizer functions. If you already own separate ND and polarizer filters or primarily shoot in controlled environments, this filter might not be the best investment.

---

If you re unsure, test it out in the field or borrow one from a friend to see if the variable design fits your workflow before committing to purchase.

Details:

It is 138mm in diameter and mounted for use third-party or custom filter holders. This 138mm Schneider Mounted Neutral Density Circular Polarizer Filter is a filter that combines solid neutral density effect and circular polarizer within single glass surface. The solid neutral density effect provides an exposure reduction of 4 stops. The addition of this quarter wave plane is to circularly polarize the linearly polarized light for use auto focus and exposure functions.

Due to how the light is broken down and filtered with a linear polarizer, auto focus exposure accuracy become skewed during use. Along with this filters solid neutral density effect is a circular polarizer that simultaneously applied to help reduce reflections and glare by filtering out light has become polarized due reflection from non-metallic surface. When the light becomes circularly polarized, it permits use of these functions. The light from the sun naturally becomes partially polarized due to reflecting off electrons in air molecules, causing scatter into what appears as haze.

A circular polarizer only differs from a linear in that it contains quarter wave plane addition to the polarizing filter. A polarizing filter arranges, and filters, this directional polarized light perpendicularly to the reflected light, allowing for absorption of much. 1.2 neutral density filter effect darkens the image, allowing you to photograph with a longer shutter speed or wider aperture than normally required and is combined circular polarizing help reduce reflections glare by filtering out light that has become polarized due reflection from non-metallic surface 16x factor provides reduction of 4 stops; allows control depth field convey movement more easily Polarizing arranges, filters, directional perpendicularly reflected light, for absorption much Clears up haze in distant landscapes saturated, vivid colors Strongest when used at 90 angle sun Circular polarizes are ideal use digital cameras auto focus lenses where linear polarizer will often disrupt auto exposure focus features Constructed water white glass increased optical clarity Non-coated Mounted ring without front rear threads third-party custom holders film television Padded pouch included storage transport This constructed as well color fidelity.
