The Tiffen 5685N9 5x6 Neutral Density (ND) 0.9 Conversion Lens Filter is a high-quality, precision-engineered accessory designed to elevate the creative possibilities of photographers working with medium-format cameras, particularly those using 5x6 film or digital backs. Crafted from Tiffen s renowned optical glass, this filter features a robust, durable construction with a sleek black anodized aluminum frame that ensures both stability and a professional aesthetic. With an ND 0.9 rating, it effectively reduces the amount of light entering the lens by three full stops, allowing photographers to achieve longer exposure times without altering the camera s aperture or shutter speed settings. This capability is invaluable for capturing smooth motion blur in waterfalls, clouds, or moving subjects, or for creating cinematic, low-light scenes with a shallow depth of field. The filter s 5x6 size ensures a perfect fit for medium-format systems, including Hasselblad, Mamiya, and other compatible cameras, while its conversion lens design minimizes vignetting and maintains image clarity across the entire frame. Whether used in landscape photography to blur flowing rivers or in portraiture to achieve dreamy bokeh effects, the Tiffen 5685N9 delivers consistent, neutral density without color cast, preserving the true tones of the original scene. Built to withstand frequent use, this filter is ideal for both studio and on-location shoots, offering photographers the flexibility to experiment with exposure techniques while maintaining professional-grade image quality.
The Tiffen 5685N9 5x6 Neutral Density (ND) 0.9 filter is a versatile tool for photographers working with medium format cameras, particularly those using 5x6 film or digital backs. Below is a detailed breakdown of its pros and cons, followed by a conclusion and recommendation.

### **Pros of the Tiffen 5685N9 5x6 ND 0.9 Filter**
1. **High-Quality Optical Clarity**
The Tiffen brand is known for producing high-grade optical glass filters. The 5685N9 is designed to minimize distortion and maintain sharpness, which is critical for medium format photography where image quality is paramount. The neutral density coating is precise, ensuring consistent color balance without introducing unwanted color casts.
2. **Versatile Exposure Control**
An ND 0.9 filter reduces light by 3 stops (since ND 0.3 1 stop, ND 0.6 2 stops, and ND 0.9 3 stops). This allows photographers to use slower shutter speeds, which is invaluable for achieving smooth motion blur in water, clouds, or other dynamic subjects. It also enables wider apertures for shallower depth of field, even in bright conditions.
3. **Medium Format Compatibility**
The 5x6 size is standard for many medium format cameras, including Hasselblad, Mamiya, and other systems. This filter fits seamlessly into existing filter systems, making it a practical addition for photographers who rely on medium format for its superior resolution and dynamic range.
4. **Durability and Build Quality**
Tiffen filters are constructed from high-quality glass and are often housed in durable metal or plastic frames. The 5685N9 is no exception, with a robust build that can withstand frequent use, including outdoor shooting where filters may be exposed to dust, moisture, or accidental impacts.
5. **Compatibility with Other Filters**
The filter can be stacked with other Tiffen filters (e.g., polarizers, color correction filters) due to its standard 5x6 size. This flexibility allows photographers to combine effects, such as using an ND filter alongside a polarizer for enhanced contrast and control.
6. **Consistent Performance**
Tiffen filters are manufactured with tight tolerances, ensuring that each filter performs consistently. This reliability is particularly important for professional work where predictability in exposure and color is critical.
7. **Professional-Grade Reputation**
Tiffen is a trusted name in the photography industry, often used by professionals and studios. The reputation for quality and performance lends credibility to the filter, especially for those investing in medium format gear.

### **Cons of the Tiffen 5685N9 5x6 ND 0.9 Filter**
1. **Cost**
High-quality ND filters, especially those designed for medium format, are expensive. The Tiffen 5685N9 is no exception, and the price may be prohibitive for hobbyists or those on a tight budget. The cost must be justified by the frequency and importance of its use.
2. **Size and Portability**
The 5x6 size makes the filter larger and heavier than smaller formats (e.g., 4x5 or 6x6). This can be cumbersome to carry around, especially for field photographers who prioritize portability. The filter may require additional space in a camera bag or case.
3. **Potential for Vignetting**
While Tiffen filters are generally well-corrected, some users report minor vignetting (darkening at the edges) when using ND filters, particularly in wide-angle or extreme compositions. This effect can be mitigated by using a lens hood or cropping the image, but it is something to consider for landscape or architectural photographers.
4. **Reflections and Ghosting**
Like all glass filters, the ND 0.9 can introduce reflections or ghosting if not used carefully. These issues are more noticeable in high-contrast scenes or when shooting directly into light sources. Proper handling and positioning can minimize these effects, but they remain a potential drawback.
5. **Limited Use Cases for Some Photographers**
Not all photographers will require a 3-stop ND filter. Those who primarily shoot in low-light conditions or use flash may find the ND 0.9 underutilized. In such cases, a lower-stop ND (e.g., ND 0.3 or ND 0.6) or a variable ND filter might be more practical.
6. **Maintenance Requirements**
Glass filters require careful cleaning to avoid scratches or dust particles that can degrade image quality. The 5x6 size makes cleaning more challenging due to its bulk, and accidental damage (e.g., from dropping or mishandling) could render the filter unusable.
7. **Alternative Options**
While Tiffen is a reputable brand, other manufacturers (e.g., B W, Lee, K&F Concept) offer similar ND filters with varying features. Some alternatives may provide additional benefits, such as multi-coating for reduced reflections or more affordable pricing. Researching these options can help determine if the Tiffen filter is the best fit.

### **Conclusion**
The Tiffen 5685N9 5x6 ND 0.9 filter is a high-quality, professional-grade tool that excels in medium format photography. Its strengths lie in its optical clarity, versatility for exposure control, durability, and compatibility with other filters. These attributes make it an excellent investment for photographers who prioritize image quality and require precise light control, such as landscape, architectural, or fashion photographers working in bright conditions.
However, the filter s drawbacks primarily its cost, size, and potential for vignetting may not align with the needs of every photographer. Hobbyists, those on a budget, or photographers who infrequently require ND effects might find it unnecessary. Additionally, users who prioritize portability or work in low-light scenarios may prefer alternatives like variable ND filters or lower-stop ND filters.

### **Recommendation**
**Buy the Tiffen 5685N9 5x6 ND 0.9 filter if:**- You are a professional or serious amateur photographer using medium format (5x6) and regularly need 3 stops of light reduction for creative effects like motion blur or shallow depth of field.
