Unlock limitless creativity with our 49mm ND4-ND64 Variable ND Filter and CPL Circular Polarizing Filter, combining versatility and clarity for impeccable shots every time.

This high-performance filter combines a Circular Polarizing Filter (CPL) to enhance colours and reduce reflections with a 2-6 F-stop Variable ND filter for precise exposure control. Made from premium Japanese optical glass with 28-layer coatings, it ensures clear, high-resolution images while offering durability and protection. Perfect for photographers seeking vibrant colours and detailed shots, this filter allows for easy adjustment of light and reflection control. This Variable ND filter does not suffer from the dark “X” effect other VND filters occasionally get at their maximum darkening position.

Enhance your photos with vibrant color and reduced glare using our circular polarizing filter.
A Circular Polarizer Filter (CPL) is an indispensable tool for any photographer who wants to capture the most stunning images possible. By reducing glare and reflections, enhancing colours, and improving contrast, this filter can help you create beautiful, eye-catching photographs. Whether you’re a professional photographer or an amateur enthusiast, a Circular Polarizer Filter is an invaluable tool that you can’t do without.

What is a Circular Polarizing Filter
A circular polarizing filter is used by photographers to reduce glare and reflections on shiny surfaces and to increase the overall saturation and contrast of a scene. This is achieved by blocking certain wavelengths of light, which can have the effect of darkening blue skies and making white clouds pop out more. Additionally, a circular polarizing filter can be rotated to adjust the amount of polarization, allowing photographers to control the intensity of the effect. This can be particularly useful for landscape photography, where it can help to make colours appear more vibrant and to make the sky appear more dramatic.

Using your filter to control your exposure
The K&F Variable ND filter gives you additional control over your exposure. This allows you to blur movement or decrease depth of field, normally impossible in the bright harsh light of day. It can restrict the amount of light entering the camera allowing you more choice in your preferred settings. Now you are able to shoot with longer exposure times or wider apertures under bright conditions. For video work it acts like an additional aperture control. A Variable ND differs from a normal ND filter in that you can control the amount of light reduction simply by rotating the filter to increase or decrease the amount of light entering the lens.

A Variable Neutral Density Filter is like a pair of sunglasses for your lens. A pair of sunglasses that you can adjust like a volume knob to control the amount of light they let through. Cameras have three ways to control exposure, aperture, shutter speed, and ISO. This filter effectively becomes a fourth control tool to manipulate light exposure. It controls the amount of light that enters your lens by opposing two polarised filters. Rotating one creates a darkening effect, which ranges in influence from 2 to 6 f-stops of light reduction. By reducing the amount of light entering the lens and sensor, a photographer can create several awesome visual image effects. These effects would not be possible in bright light conditions without a variable ND. Simply adding the filter to the lens gains you your first f-stop of light reduction. If you have ever visited a beach, desert or salt flats you will know how much you appreciated having sunglasses with you. Under those extreme lighting conditions you camera sits with all its exposure controlling settings topped out. The amount of artistic control you can take becomes limited by the restriction of all values being maxed. Adding dialable “sunglasses” to your camera reopens creative possibilities.

Why Photographers Love It
Photographers love this 2-in-1 CPL and Variable ND4-64 filter because it offers the versatility and convenience of two essential tools in one compact device. The Circular Polarizing Filter (CPL) enhances color saturation and contrast while reducing unwanted reflections from surfaces like water and glass, making skies bluer and foliage more vibrant. Meanwhile, the Variable ND4-64 filter provides adjustable light reduction (from 2 to 6 f-stops), allowing photographers to precisely control exposure and achieve effects like motion blur or shallow depth of field, even in bright conditions. This combination eliminates the need to swap, or even stack filters, saving time and reducing the gear they need to carry, making it a highly practical and efficient choice for photographers who value both quality and convenience.

The Nano-X difference
K&F Concept’s Nano-X Series of filters are crafted for the demands of UHD capture. When you want 8k resolutions, use a filter that is designed for uncompromising quality. This Nano-X filter is precision engineered from Japanese optical glass and is specifically designed to meet the high-resolution capture abilities that modern digital cameras are capable of. They are made up of 28-layer nano-coating technology and a double-sided polishing process. The most prominent of these coatings, is the anti-reflection coating, which effectively reduces internal reflection problems such as flares and ghosting. Another benefit of these coatings is that they increase the effective light transmittance through the filter. These coatings allow the filters to achieve high-definition picture quality and be waterproof. It also helps them to have a high level of scratch resistance and grease does not adhere well to the surface. Fingerprints wipe off very well instead of just smearing.

Elevate your photography with the ultimate 2-in-1 CPL and Variable ND4-ND64 filter, designed to unlock your creative potential. This high-performance filter enhances color, reduces reflections, and provides precise exposure control, all while maintaining the clarity and sharpness essential for high-resolution images. Crafted from premium Japanese optical glass with 28-layer nano coatings, it ensures durability and top-tier performance, making it an indispensable tool for photographers who demand both quality and convenience. Take your shots to the next level-order now and transform your photography experience!
