Review TIFFEN New 40.5mm Water White Glass Nd 1.2 Filter Mfr #w405nd12

The Tiffen W405ND12 40.5mm Water Glass Neutral Density (ND) 1.2 filter is a premium optical accessory designed for photographers seeking to master the art of long-exposure and slow-shutter photography while maintaining the natural color rendition of their scenes. Crafted from high-quality, precision-machined water glass, this filter delivers exceptional clarity and minimal color cast, ensuring that your images retain their true tonal balance without the artificial tinting often associated with plastic-based filters. The 4-stop ND rating (ND1.2) allows photographers to extend exposure times by a full four stops, effectively reducing the amount of light entering the lens by 94%, which is ideal for creating silky water effects, smooth motion blur in clouds or foliage, or achieving creamy bokeh in low-light conditions. The 40.5mm diameter accommodates a wide range of professional and semi-professional lenses, making it a versatile choice for photographers working with full-frame or APS-C cameras, though an adapter ring may be required for lenses with different thread sizes. Built to withstand the rigors of frequent use, the W405ND12 features a durable, scratch-resistant coating that preserves optical integrity over time, while its sleek, minimalist design ensures it blends seamlessly into any photography setup. Whether used in landscape, architectural, or creative portraiture, this filter empowers photographers to explore new artistic possibilities by controlling light in ways that would otherwise be impossible with standard exposure settings. Its precision-engineered construction and commitment to optical purity make it a staple in the toolkit of both emerging and seasoned photographers who demand the highest standards in image quality.

The Tiffen W405ND12 4-stop neutral density (ND) filter is a popular choice for photographers who need to control exposure in bright conditions while maintaining sharpness and color accuracy. Below is a detailed breakdown of its pros and cons, followed by a conclusion and recommendation.

### **Pros of the Tiffen W405ND12 40.5mm ND 1.2 Filter**

1. **High-Quality Optical Performance**

The Tiffen W405ND12 is made with high-grade optical glass, which minimizes chromatic aberration and ensures sharp, distortion-free images. Tiffen is known for its precision manufacturing, making this filter a reliable choice for professional and semi-professional photographers.

2. **Accurate Neutral Density**

As a true neutral density filter, it reduces light evenly across all wavelengths (RGB spectrum) without altering color balance. This is crucial for maintaining natural colors in long-exposure photography, such as waterfalls, cityscapes, or motion blur effects.

3. **Durable Construction**

Tiffen filters are built to withstand harsh conditions, including saltwater, dust, and scratches. The W405ND12 features a robust metal frame and a scratch-resistant coating, making it suitable for outdoor use.

4. **Versatile for Multiple Applications**

The 4-stop ND (ND1.2) is ideal for long exposures in bright daylight, allowing photographers to use slower shutter speeds (e.g., 1/4s to 1/8s) without overexposing the image. It works well for:

- Landscape photography (smooth water, silky clouds)

- Architectural shots (motion blur in traffic)

- Videography (cinematic slow-motion effects)

- Astrophotography (longer exposures of stars)

5. **Threaded for Easy Attachment**

The 40.5mm thread size is standard for many lenses, making it compatible with a wide range of DSLR and mirrorless cameras. Tiffen includes a step-down ring (ND12) to adapt it to smaller lens diameters (e.g., 37mm, 43mm).

6. **Minimal Vignetting**

Unlike some ND filters, the W405ND12 does not introduce significant vignetting (darkening at the edges), which helps maintain consistent exposure across the entire frame.

7. **Good Value for Professional Use**

While not the cheapest ND filter on the market, it offers a strong balance between performance and cost, especially when considering its durability and optical quality.

### **Cons of the Tiffen W405ND12 40.5mm ND 1.2 Filter**

1. **Expensive Compared to Cheaper Alternatives**

Tiffen filters are premium products, and the W405ND12 is priced higher than basic ND filters from brands like K&F Concept or B W. Budget-conscious photographers may find more affordable options with similar stop ratings.

2. **Requires a Step-Down Ring for Smaller Lenses**

The filter itself is 40.5mm, but the included ND12 step-down ring allows it to fit lenses with smaller diameters (e.g., 37mm). However, if you have multiple lenses with varying thread sizes, you may need additional adapters, adding to the cost.

3. **Not Polarizer-Compatible**

If you plan to use a polarizing filter in combination with this ND filter, you ll need a polarizer that fits the same thread size (or a multi-coating polarizer that works with ND filters). Some photographers prefer to stack filters, but this can introduce slight vignetting or ghosting if not done carefully.

4. **Weight and Bulk**

ND filters, especially higher-stop versions, can add noticeable weight to your lens. While not excessive for this filter, frequent long-exposure shooters may find it slightly cumbersome compared to lighter alternatives.

5. **Potential for Light Leakage in Some Mounts**

If the filter is not seated properly in the lens mount, there s a small risk of light leakage around the edges. This is rare with Tiffen s quality construction but can occur if the filter is damaged or misaligned.

6. **Limited to 4-Stop ND**

While 4-stop is useful, some photographers prefer variable ND filters (which adjust density on the fly) or higher-stop filters (e.g., 6-stop or 10-stop) for extreme conditions. This filter is fixed at 4-stops, so you ll need additional filters for different scenarios.

---

### **Conclusion**

The Tiffen W405ND12 4-stop ND filter is one of the best mid-range ND filters available, offering excellent optical quality, durability, and versatility. It excels in scenarios where you need consistent, color-accurate neutral density without sacrificing sharpness. The inclusion of a step-down ring makes it adaptable to multiple lens sizes, and its reputation for reliability ensures long-term use.

However, its higher price point and the need for additional adapters for smaller lenses may deter budget-conscious photographers. If you prioritize image quality and professional-grade performance, this filter is an excellent investment. For those on a tighter budget, cheaper alternatives (like K&F Concept or B W) may suffice, though they may lack the same level of precision and durability.

---

### **Recommendation**

- You are a professional or serious amateur photographer who values optical quality and durability.

- You frequently shoot long exposures in bright daylight and need a reliable 4-stop ND filter.

- You already own a 40.5mm lens or plan to use it with lenses that require a step-down ring.

- You want a filter that minimizes vignetting and color shift.

- You are on a tight budget and can compromise slightly on build quality (e.g., K&F Concept ND filters).

- You prefer variable ND filters for more flexibility in the field.

- You primarily shoot with lenses that don t require a step-down ring, and you d rather invest in a filter with a native thread size.

The Tiffen W405ND12 is a top-tier ND filter that delivers professional results. While it s not the cheapest option, its performance justifies the cost for photographers who demand the best. If you re serious about long-exposure photography, this filter is a strong recommendation.
