Master light with variable exposure reduction, control the light and elevate your photography game

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 1 to 9 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 reduction of light. 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.

The Nano-X Series of Filters
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. The filter is crafted from high precision Japanese optical glass. The lens is treated with a double-sided polishing process which ensures high-definition image quality at up to 8k. The filter also undergoes a double-sided multilayer coating process where 28 layers is applied to the lens. Coatings effectively reduce reflections, increase effective light transmittance through the filter and avoids ghosting. The outer layer coating is hydrophobic to help repel water and are scratch resistant ensuring the longevity of your filter. The filter glass is larger than the threaded mount to further help reduce vignetting, even when using a wide-angle lens. It also helps give a filter effect which is consistent over the entire frame.

The dark X
Through the polarisation mechanic used by Variable ND filters it is possible to form a dark X cross shape across the frame when dialled in at the extreme limit of the darkening effect. This is caused through a combination of focal length, lens type and the natural mechanical physics of cross polarization. This is not a filter quality problem, it is an inevitable byproduct which can occur under specific conditions. It is easily corrected by rotating the outer filter ring away from the zone where that effect is evident. If your specific needs are for a Variable ND filter free of the dark X cross, consider the K&F ND8-ND128 which is a 3-7 stop filter and is free of this effect.

Utilizing a Variable ND filter like this K&F model offers several advantages for photographers and videographers. By slowing the shutter and extending exposure times, you can achieve a captivating motion blur effect, effectively contrasting static and moving subjects in your images. Additionally, the filter allows for a shallow depth of field, enabling the isolation of the main subject with a soft blur in the background. For videographers, the Variable ND filter provides convenient aperture control, often absent in many lenses. This feature proves valuable for achieving a cinematic style in video creation. Moreover, the filter's versatility streamlines gear and minimizes time spent swapping filters, making it an ideal all-in-one solution for photographers on the go.

The K&F Variable ND Filter has a smart ultra slim frame design machined from the best quality aircraft aluminium. This ensures the frame is strong, durable and also very lightweight. It will stand up to continuous use, day in and day out. The textured frame helps to add extra grip to the surface. This model has a rotation tab which gives you extra leverage and control over the rotation of the outer filter ring. You can screw it on securely with less risk of accidentally dropping the filter and you can rotate it more easily to dial in the value you after. The smooth action allowing perfect light reduction between 1 and 9 f-stops. There are no hard stops, so you can intuitively dial in the darkening effect with your eye. You will also find handy dot and arrow calibration marks to help make results repeatable. The frame is double threaded so you can combine the effects of more than one filter type, allowing you to adapt the mood and atmosphere to fit any occasion or condition.

A PU leather case for your filter is included in the kit. The pouch has a magnetic flip cover. Lifting the cover reveals a fabric pull tab for simple and quick access to your filter. Pull the orange tab to safely lift the filter from its case without touching the glass. A great filter is worth protecting.

Screwing this variable ND filter on the front of your lens will help you manipulate and control the amount of light that enters your lens and sensor. With the K&F Variable ND Filter in front of your lens, you have a world of creative possibilities at your fingertips. From motion blur effects to shallow depth of field, you can do it all with the K&F Variable ND Filter. It’s got you covered from 1-9 f-stops. So, if you are trying to streamline the amount of gear you carry to your shooting location or just need a great all-rounder ND, buy the K&F Variable ND Filter from the Nano-X series. As with all K&F products, the price will put a smile on your face.
