Review K F CONCEPT Variable 67mm Magnetic Lens Filter Nano x Mrc New

The **Kowa KF01.1851 ND2-32 67mm Magnetic Lens Filter Nano-X MRC** is a high-performance, multi-coating optical filter designed specifically for professional photography and videography, offering unparalleled versatility and precision in low-light conditions. Part of Kowa s renowned **Nano-X MRC (Multi-Resonance Coating)** series, this filter combines advanced optical engineering with robust magnetic mounting technology to deliver exceptional image clarity, color fidelity, and light control. The **ND2-32 graduated neutral density filter** features a seamless, 32-stop density gradient that transitions smoothly from full strength (ND2) at the top to clear glass at the bottom, allowing photographers and videographers to balance exposure across high-contrast scenes such as landscapes with bright skies and dark foregrounds without sacrificing detail or introducing visible seams. The **magnetic lens filter system** eliminates the need for traditional filter holders, enabling quick, hands-free adjustments and reducing the risk of misalignment or ghosting, which is particularly advantageous for dynamic shooting scenarios like travel, astrophotography, or action videography. Engineered with **multi-layered Nano-X MRC coatings**, this filter minimizes reflections, flare, and chromatic aberration while maintaining a natural color rendition, ensuring that every captured frame retains its original vibrancy and depth. The **67mm diameter** accommodates a wide range of lenses, from mid-format to full-frame DSLRs and mirrorless cameras, making it a versatile addition to any serious photographer s or filmmaker s toolkit. Whether used in portraiture to soften harsh sunlight, in landscape photography to preserve dynamic range, or in cinematic videography to achieve cinematic bokeh effects, this filter exemplifies Kowa s commitment to innovation and optical excellence, providing photographers with a reliable solution for mastering exposure in demanding lighting conditions.

The **K&F Concept Nano-X MRC 67mm ND2-32 Variable ND Filter** is a popular choice among photographers and videographers for its versatility in controlling light exposure. Below is a detailed breakdown of its pros and cons, followed by a conclusion and recommendation.

---

### **Pros**

1. **Variable Neutral Density (ND) Range**

The filter offers a broad ND range from **ND2 (1 stop) to ND32 (5 stops)**, allowing for significant exposure adjustments without altering white balance or color temperature. This is particularly useful in bright conditions where you need to slow down shutter speeds for motion blur (e.g., long exposures, cinematic shots) or wider apertures (e.g., shallow depth of field in daylight).

2. **Compact and Lightweight Design**

The Nano-X series is designed to be slim and lightweight, making it easier to carry than traditional screw-in ND filters. This is ideal for travel, street photography, or videography where weight matters.

3. **Magnetic Attachment System**

The magnetic mounting system allows for quick and easy attachment/detachment without needing to remove the lens cap. This is convenient for field use, as you can switch between filters or remove them entirely when not needed. The system also reduces the risk of losing or misplacing the filter.

4. **Multi-Coated Optics**

The filter claims to have **multi-coating** to minimize flare and ghosting, which helps maintain image clarity and sharpness, especially in backlit or high-contrast scenarios.

5. **Versatility for Photography and Videography**

The variable ND is particularly useful for videographers who need consistent exposure across different lighting conditions without adjusting settings manually. Photographers can also benefit from the ability to shoot at wider apertures in daylight without overexposing the image.

6. **Affordable Price Point**

Compared to high-end variable ND filters from brands like Lee, Singh-Ray, or B W, the K&F Concept Nano-X offers a cost-effective alternative with similar functionality. This makes it accessible for beginners or hobbyists on a budget.

7. **Compatibility with Most Lens Hoods**

The 67mm size is a standard diameter that works with many lenses, and the slim profile should not interfere with most lens hoods.

### **Cons**

1. **Build Quality and Durability**

While the filter is lightweight, some users report concerns about its **durability**, particularly the magnetic mounting system. Cheap magnets or poorly aligned components can lead to misalignment or failure over time. The plastic housing may also feel less robust than metal alternatives.

2. **Optical Quality and Color Shift**

Some reviews mention **slight color fringing or a minor color cast** at the edges, especially at higher ND settings. While not severe, this can be noticeable in high-contrast scenes or when shooting in RAW and zooming in. The multi-coating is supposed to mitigate this, but results may vary.

Additionally, variable ND filters can sometimes introduce **slight vignetting** or uneven exposure across the frame, though this is less common with the Nano-X line.

3. **ND2-32 Range May Be Overkill for Some**

The **ND2 (1 stop) is quite weak**, and many users find that they rarely need such a low ND setting. The filter starts at ND2, which means you ll often be using ND4 or higher, leaving the ND2 portion underutilized. Some photographers prefer filters that start at ND4 or ND8 for better practicality.

4. **Magnetic Attachment Limitations**

While convenient, the magnetic system is not foolproof. Strong vibrations (e.g., from a camera shake or wind) can cause the filter to detach. Additionally, the magnets may not work reliably with certain lens coatings or hoods, especially if they are metallic.

5. **No Physical ND Markings**

Unlike some filters that have physical markings or a dial to indicate the current ND setting, the Nano-X relies on a **digital display on the filter itself**. This can be less intuitive for some users, especially in low light or when the display is not clearly visible.

6. **Potential for Lens Fogging**

If the filter is not properly sealed, moisture or condensation could accumulate inside, affecting optical clarity. While rare, this is a risk with any filter, especially in humid conditions.

7. **Limited Brand Reputation**

K&F Concept is a well-known brand in the photography accessory space, but it is not as established as traditional filter manufacturers like B W, Hoya, or Schneider Kreuznach. This means there may be fewer third-party reviews, repair options, or long-term performance data compared to more established brands.

---

### **Conclusion**

The **K&F Concept Nano-X MRC 67mm ND2-32 Variable ND Filter** is a **solid, budget-friendly option** for photographers and videographers who need a versatile ND filter without breaking the bank. Its **variable range, magnetic attachment, and compact design** make it a practical choice for on-the-go use, especially for those who prioritize convenience and affordability.

However, **potential issues with build quality, optical consistency, and durability** mean it may not be the best choice for professionals or those who demand the highest optical performance. If you re working in controlled environments or shooting with high-end gear, investing in a more premium filter (e.g., from Lee, Singh-Ray, or B W) might be worth the extra cost for better longevity and optical quality.

For **beginners, travel photographers, videographers, or hobbyists** who need a reliable, portable ND filter for general use, the Nano-X is a **good value**. If you re concerned about durability or optical perfection, consider pairing it with a **high-quality lens hood** and handling it with care.

---

### **Recommendation**

- You need a **budget-friendly variable ND filter** for photography or videography.

- You prioritize **portability and ease of use** (magnetic attachment).

- You shoot in **bright conditions** where you need to slow down shutter speeds or use wider apertures.

- You re okay with **minor trade-offs in build quality and optical perfection** for the price.

- You require **industrial-grade durability** or plan to use it in harsh conditions.

- You re sensitive to **color fringing or vignetting** and need pristine optical quality.

- You prefer **physical ND markings** or a more intuitive interface.

- You re a professional who relies on **consistent, high-end performance** from every accessory.

- For **better build quality and optics**, consider the **Lee Filters Big Stopper Variable ND** or **Singh-Ray Variable ND**.

- For **a more affordable screw-in option**, the **Hoya HD Variable ND** or **B W XS-Pro Variable ND** are worth exploring.

- If you primarily need **ND8 or ND16**, a **fixed ND filter** (e.g., K&F Concept ND8 or ND16) may be sufficient and more cost-effective.

Ultimately, the Nano-X is a **great entry-level variable ND filter** that delivers on its core promise of versatility and convenience. Weigh its pros and cons against your specific needs before purchasing.
