I recently had the pleasure of trying out the K&F Concept 40.5mm Variable ND Lens Filter, and I must say, it’s been a game-changer for my photography! This filter is engineered to eliminate the pesky ‘X’ cross that often appears in images when using variable ND filters on wide-angle and telephoto lenses. The self-lock frame design ensures a secure fit without compromising the quality of your shots. ,One feature I find particularly impressive is the use of imported AGC glass, which provides excellent color balance with no color cast. This ensures that my images maintain their clarity and sharpness. The 28 multi-layer nanometer coatings, developed by K&F Concept’s optical engineers, offer waterproof, scratch-resistant, and anti-glaring protection for the valued lens. The ultra-slim frame design is another standout feature. It effectively avoids vignetting, even with a 28mm focal length, making it ideal for wide-angle photography. The CNC-non-slip design also makes it easy to install and remove the filter. ,However, I would like to remind potential buyers that this filter kit is compatible with all 40.5mm lenses. Make sure to verify your camera’s lens thread size before ordering. Also, note that the lens cap/hood size should be 43mm for the 40.5mm nd filter. Lastly, I want to mention that packaging may vary between new and old shipments, so don’t be alarmed if you receive a different package than what was shown online. , Overall, I highly recommend the K&F Concept 40.5mm Variable ND Lens Filter for any photographers looking to improve their wide-angle and telephoto shots without worrying about the ‘X’ cross issue or vignetting. The high-quality materials used in its construction ensure excellent color balance, clarity, and sharpness in your images.
