The **72mm 875 Series Circular Polarizing Filter (CPL) with a 72e Edge** from the renowned **B W (Baader Planetarium)** line is a premium optical accessory designed to elevate the quality and versatility of your photography and astrophotography endeavors. Engineered with meticulous precision, this filter combines cutting-edge **multi-layer dielectric coating** with **high-grade Schott optical glass**, ensuring exceptional clarity, minimal color fringing, and superior light transmission across the entire visible spectrum. The **circular polarization (CPL) mechanism** allows photographers to dynamically adjust polarization levels, effectively reducing glare, enhancing contrast, and deepening the saturation of skies, foliage, and water surfaces without altering the original hue ideal for landscape, travel, and macro photography. The **72e Edge** mounting system features a **smooth, rounded edge** that minimizes vignetting and ensures a seamless transition between the filter and your lens, while the **metallic black frame** not only enhances durability but also provides a sleek, professional aesthetic. Built to withstand rigorous use, this filter is housed in a **robust, weather-sealed metal box**, complete with a **protective foam insert** that safeguards the glass during transit and storage. Whether you re capturing the vibrant hues of a sunset, the intricate details of a forest canopy, or the celestial wonders of the night sky, the **B W 72mm 875 CPL** delivers consistent, professional-grade performance, making it an indispensable tool for serious photographers seeking to push the boundaries of their craft.
### **Analysis of the 72mm Circular-Polarizing (CP) Polarizing Filter (Model: 012240621613, 72mm, 875 Series)**
#### **Pros:**1. **High-Quality Optical Clarity** The 875 series is known for its excellent optical coatings, reducing flare and ghosting while maintaining sharp, vibrant colors. This is particularly useful in bright outdoor or backlit scenes where stray light can degrade image quality.
2. **Circular Polarization (CP) Functionality** Unlike linear polarizers, circular polarizers work with modern autofocus cameras and electronic viewfinders. They effectively reduce glare from water, glass, and skies while enhancing contrast and saturation in landscapes and cityscapes.
3. **Durable Construction** The filter appears to be built with high-quality glass and metal framing, suggesting resistance to scratches and warping over time. The 72mm thread is standard, making it compatible with most 72mm lens hoods and extension tubes.
4. **Versatility** Works well with a wide range of photography genres, including landscape, real estate, and travel photography, where glare reduction is beneficial.
5. **Brand Reputation** If this is from a reputable manufacturer (e.g., B W, Hoya, or similar), it likely comes with a good warranty and customer support, ensuring reliability.
6. **Easy to Use** The rotation mechanism is typically smooth, allowing photographers to quickly adjust polarization strength without slipping.

#### **Cons:**1. **Potential for Vignetting** Some polarizing filters, especially when used at wide apertures (e.g., f/2.8 or wider), can cause slight darkening at the edges of the frame. While modern filters are often designed to minimize this, it s still a consideration for wide-angle lenses.
2. **Cost** High-quality polarizing filters are not cheap. If you already own a linear polarizer or don t frequently use polarization, this may not be a cost-effective upgrade.
3. **Weight and Bulk** Adding a polarizer increases the weight of your lens setup, which can be tiring during long shoots or travel. However, the 72mm size is relatively standard and not overly bulky.
4. **Limited Use Cases** Polarizers are most useful in specific scenarios (e.g., landscapes, reflections). For other genres like portraits or low-light photography, they may not be necessary.
5. **Compatibility Issues (If Not CP)** If this filter is not truly circular-polarized (though the description suggests it is), it could interfere with autofocus and electronic viewfinders on DSLRs/mirrorless cameras, rendering it useless in those situations.
6. **Potential for Scratches** Like any glass filter, it can scratch over time, especially if not handled carefully. A protective lens cap is recommended.

### **Conclusion:**This **72mm circular-polarizing filter (875 series)** is a solid investment if you frequently shoot landscapes, real estate, or scenes where glare reduction is beneficial. Its high optical quality, durability, and compatibility with modern cameras make it a worthwhile addition for photographers who prioritize image clarity and versatility. However, if you rarely use polarization or already have a linear polarizer, the cost may not justify the purchase.
### **Recommendation:**- **Buy it if:** You shoot landscapes, travel, or real estate often and need reliable glare reduction. The 875 series is a trusted brand, and the circular polarization ensures compatibility with autofocus systems.
- **Skip it if:** You don t frequently use polarizers, already own a linear polarizer, or prefer to keep your lens setup minimal. In that case, consider a cheaper alternative or wait for sales.
- **Alternative Consideration:** If budget is a concern, a mid-range circular polarizer from a reputable brand (e.g., Hoya HD or B W XS-Pro) offers similar performance at a lower cost.
For most photographers who need a high-quality polarizer, this filter is a strong choice. Just ensure proper handling to avoid scratches and consider pairing it with a lens hood to further reduce flare.
