37mm 3 in 1 CPL & Variable ND2~ND32 & Black Mist 1/4 Lens Filter HD waterproof scratch-resistant, 28 layers green coated, without black cross (Nano-X Series) description:

• 3 in 1 filter – One filter supports light reduction, creates a dreamy effect, and enhances color and contrast of images, widely fitting most photography needs and providing more creative options for your images. Double-sided 28-layer coatings ensure resistance against water, oil, dust, and scratches, with imported optical AGC glass material delivering crystal-clear results. A 40.5mm lens cap is required for this 37mm filter.

• No "X" cross on images – The filter frame adopts self-locking technology and rotates infinitely between 1 and 5 stops (ND2-32), facilitating the positioning of light reduction and avoiding the phenomenon of producing black crosses.

• Soft highlight flares, lowered contrast – This black mist 1/4 filter can soften facial skin's wrinkles, freckles, and pores, making it more delicate, plump, and gorgeous. The mist dream effect can be better realized by showing the film effects dreamily.

• Enhance color & contrast – The CPL filter allows you to remove unwanted reflections from non-metallic surfaces such as water and glass, enhancing color saturation and contrast. This effect is often used to increase the contrast and saturation in blue skies and white clouds.
