Review SCHNEIDER 4.5 Inch Circular Polarizing True pol 1/2 Lens Filter

The **Schneider 85mm Kreason 4.5x85 Polarizing True-Pol 1/2" Lens Filter** is a high-performance optical accessory designed for photographers and videographers who demand exceptional image clarity, contrast, and color fidelity. Crafted by Schneider Optics, a brand synonymous with precision engineering and superior glass quality, this filter exemplifies the brand s commitment to delivering professional-grade tools for demanding creative work. The **Kreason series** is renowned for its exceptional sharpness, minimal vignetting, and near-flawless optical performance, making it a preferred choice among filmmakers, still photographers, and content creators who shoot in challenging lighting conditions.

This **polarizing filter** operates on a **True-Pol mechanism**, which ensures a smooth, uninterrupted rotation of the polarizing element without the abrupt clicks or resistance often found in conventional filters. This feature is particularly valuable for videographers, as it allows for seamless adjustments to polarization levels without the risk of introducing unwanted artifacts or misalignment during dynamic shots. The **4.5-stop polarization** capability is a standout attribute, enabling photographers to dramatically reduce glare, haze, and reflections from non-metallic surfaces like water, glass, or foliage, resulting in richer skies, deeper blues, and more vibrant landscapes. For videographers, this means cleaner, more professional footage with enhanced contrast and reduced lens flare, even in bright outdoor environments.

Constructed from **high-quality optical glass**, the filter is coated with **Schneider s proprietary multi-layer anti-reflective (AR) coatings**, which minimize internal reflections and ghosting, ensuring maximum light transmission and image purity. The **1/2" thread** design allows for easy integration with Schneider s extensive line of lens adapters, making it versatile for use with a wide range of camera lenses, from wide-angle to telephoto. The **85mm diameter** strikes a balance between usability and compatibility, fitting seamlessly on mid-to-large format lenses while remaining practical for everyday photography. The filter s **durable metal frame** is designed to resist warping or distortion over time, even in harsh conditions, ensuring long-term reliability.

Whether you re capturing cinematic landscapes, architectural photography, or high-end video production, the **Schneider 68-020145** delivers a level of optical excellence that elevates your work. Its **True-Pol mechanism** and superior glass quality make it a standout choice for professionals who refuse to compromise on image quality. For those who prioritize precision, durability, and unmatched optical performance, this filter is an indispensable tool in achieving flawless, high-end visuals.

### **Pros and Cons of buying a Schneider 68-020145 4.5-85 Polarizing True-Pol 1/2" Lens Filter**

1. **High-Quality Polarization** Schneider is a well-respected brand known for producing high-grade optical filters. The True-Pol design minimizes ghosting and flare, ensuring cleaner, more natural images, especially in bright outdoor or reflective conditions.

2. **Wide Zoom Range (4.5 85mm)** This filter is designed for a broad focal length range, making it versatile for a variety of lenses. It can be used effectively on telephoto, standard, and some wide-angle lenses (though very wide-angle lenses may still benefit from a dedicated circular polarizer).

3. **True-Pol Technology** Unlike standard linear polarizers, which can create ghosting or darkening issues, Schneider s True-Pol construction uses a special coating that maintains consistent polarization across the entire zoom range, reducing artifacts.

4. **Durable Construction** Schneider filters are built with high-quality glass and robust metal frames, ensuring longevity and resistance to scratches or warping over time.

5. **Professional-Grade Performance** Ideal for photographers who demand the best image quality, particularly in landscape, travel, or outdoor photography where polarization helps reduce glare and enhance colors.

6. **1/2" Thread Size** While this may limit compatibility with some larger lenses, it is a standard size that works well with many mid-range and telephoto lenses, especially on DSLRs and mirrorless cameras.

1. **Expensive** Schneider filters are premium products, and this particular polarizer is priced higher than many alternatives. For casual photographers or those on a budget, this may not be justified.

2. **Limited Focal Range** While the 4.5 85mm range covers a lot of ground, very wide-angle lenses (e.g., 10 24mm) may still require a separate circular polarizer for optimal results. Some users may need to purchase additional filters to cover their entire lens range.

3. **Size and Weight** As a large zoom polarizer, it is bulkier and heavier than a standard fixed polarizer, which could be less convenient for travel or when carrying multiple filters.

4. **Compatibility Issues** The 1/2" thread size means it won t fit larger lenses (e.g., many full-frame DSLRs with 77mm or 82mm mounts). Users with larger lenses may need an adapter or a separate filter.

5. **Overkill for Some Uses** If you primarily shoot in controlled environments (e.g., studios) or don t frequently encounter glare, the benefits of a high-end polarizer may not be necessary.

---

The Schneider 68-020145 4.5 85mm True-Pol polarizing filter is an excellent choice for photographers who prioritize image quality, versatility, and durability. Its True-Pol technology ensures minimal ghosting and consistent performance across a wide zoom range, making it ideal for outdoor, landscape, and travel photography. However, its high cost and limited compatibility with very wide-angle or large-format lenses may make it less practical for some users.

If you frequently work with mid-to-telephoto lenses and need a reliable polarizer to reduce reflections and enhance colors, this filter is a strong investment. For budget-conscious photographers or those with very wide-angle lenses, a standard circular polarizer or a lower-cost alternative might suffice.

- **Buy it if:** You shoot primarily with mid-to-telephoto lenses, value Schneider s reputation for optical quality, and need a high-performance polarizer for outdoor or reflective subjects.

- **Skip it if:** You have a very wide-angle lens (e.g., 10 24mm), shoot mostly in controlled environments, or are on a tight budget. In that case, a standard circular polarizer (e.g., from B W or Hoya) may be a more practical choice.
