I recently had the pleasure of trying out the K&F Concept 46mm Variable ND Lens Filter, and I must say, it has become an indispensable part of my photography kit. The filter’s self-lock frame design is a game-changer, as it effectively eliminates the pesky ‘X’ cross that often appears in images with traditional variable ND filters.

This filter is made using imported AGC glass, a first-class material that ensures excellent color balance without any color cast. The image clarity and sharpness remain unaffected, which is a testament to the quality of this product.

What truly sets this filter apart, however, are the 28 multi-layer nanometer coatings developed by K&F Concept’s optical engineers. These coatings make the filter waterproof, scratch-resistant, and anti-glaring, providing superior protection for your valued lens.

The ultra-slim frame design is another feature that I find incredibly useful. With a thickness of just 7.4mm, it effectively avoids wide-angle vignetting, even on focal lengths as narrow as 28mm. The CNC-non-slip design also makes installation and removal effortless.

A word of caution ensure your camera lens thread size is indeed 46mm before ordering, as the kit is compatible with all 46mm lenses. Also, note that the lens cap/hood size should be 49mm for this filter. Lastly, please be aware that new and old packages are sent randomly.
