Introduction to the K&F Concept True Color Variable ND Filter ND2-ND32

Technical Specifications

The K&F Concept True Color Variable ND2-ND32 filter stands out for its robust construction and multiple layers of coating. Here are its main technical specifications:

  • 6H Hardness: This filter has scratch resistance that allows it to withstand most contacts with everyday metal objects. However, it remains sensitive to harder elements, such as sand, requiring careful handling to avoid damaging the filter surface.

  • 28 Layers of Nano Coatings: These coatings ensure an anti-glare effect, preventing unwanted light flare in direct sunlight. The filter has an ultra-low reflectivity of less than 0.2%, ensuring sharp images without undesirable reflections.

  • Dust and Stain Resistant Coating: These additional treatments provide increased durability and easy maintenance by minimizing dust and stain adhesion on the filter surface.

  • CNC-Machined Frame: This non-slip frame allows for easy and quick installation and removal of the filter, even in challenging conditions. However, avoid handling it with oily fingers. The design is intended for ergonomic and practical use in the field.

  • Adjustment Ring with Knob: A small, precise knob allows for easy adjustment of the filter’s transparency, offering optimal control for every shooting situation.


Design and Ergonomics

The K&F Concept ND2-ND32 filter is not only high-performing but also aesthetically pleasing. The CNC-machined frame gives it a professional and robust appearance.


The knob on the adjustment ring is an excellent addition, allowing for precise and quick adjustments of the filter's density, even during a shoot or photo session. The filter comes with an elegant and practical protective case, designed to safely store the filter when not in use.



Performance and Usage


Optical Quality and Reliability


One of the major strengths of this variable ND filter is its ability to maintain excellent image quality regardless of the chosen neutral density level. Unlike other ND filters on the market, the ND2-ND32 True Color does not introduce yellow or orange discoloration, even at higher density levels, and it does not exhibit the "black X" phenomenon often seen with wide-angle lenses. This makes it a reliable tool for professional photographers and videographers, whether for long exposure shots or videos requiring precise light control.


Ease of Use


In practice, the filter is easy to handle thanks to its non-slip frame. Adjusting the density using the knob is smooth and precise, allowing for quick transitions between different transparency levels without effort. It is also compatible with many lenses due to the various sizes available to fit all lens diameters. If you are looking to purchase only one, we recommend getting the largest size compatible with your lenses and buying a step-down ring set to use it on other lenses with smaller filter threads.




Advantages and Disadvantages

Advantages


  • High-Quality Materials and Coatings: The 28 layers of nano coating and the CNC-machined aluminum construction ensure great durability and excellent image quality.

  • No Distortion or Coloration Issues: Unlike many ND filters on the market, this one does not exhibit the "black X" effect or yellow/orange discoloration, placing it among the best filters in its category.

  • Practicality and Aesthetics: Its design is both functional and elegant, and it comes with a high-quality protective case.

  • Versatility: The ND2-ND32 True Color filter performs well in both photography and videography, offering great flexibility in use.



Disadvantages

  • Incompatibility with Lens Hoods: Unfortunately, this filter is not compatible with lens hoods, which can be a drawback in certain shooting situations. It might be advisable to use an additional accessory (or even your hand, although we don’t recommend this as it can be risky) to shade the lens if needed.

  • Sensitivity to Sand Scratches: While resistant to common scratches, it is sensitive to harder particles like sand, which requires careful handling during beach sessions. Consider bringing a blower and a brush to remove any small grains that might settle on the filter.


User Experience

The user experience with the ND2-ND32 True Color filter is generally very positive. Whether for landscape photography, where exposure control is crucial, or for videos requiring reduced light flow, this filter delivers impeccable image quality. The precise adjustment system is particularly appreciated, allowing for quick adaptation to changing conditions without sacrificing quality.


Recommended Applications

  • Landscape and Architecture Photography: Ideal for long exposures in daylight.

  • Videography: Perfect for outdoor videos requiring fine light control, such as weddings.

  • Studio Photography: Useful for controlling exposure indoors without affecting color or sharpness.
