MASTER LIGHT WITH VARIABLE EXPOSURE REDUCTION, CONTROL THE LIGHT AND ELEVATEYOUR PHOTOGRAPHY GAMEThe K&F Variable ND filter gives you additional control over your exposure. Thisallows you to blur movement or decrease depth of field, normally impossible inthe bright harsh light of day. It can restrict the amount of light entering thecamera allowing you more choice in your preferred settings. Now you are able toshoot with longer exposure times or wider apertures under bright conditions. Forvideo work it acts like an additional aperture control. A Variable ND differsfrom a normal ND filter in that you can control the amount of light reductionsimply by rotating the filter to increase or decrease the amount of lightentering the lens. What really separated this filter from its counterparts isits magnetic attachment function. K&F Concept's Nano-X Series of filters arecrafted for the demands of UHD capture. When you want 8k resolutions, use afilter that is designed for uncompromising quality.A Variable Neutral Density Filter is like a pair of sunglasses for your lens. Apair of sunglasses that you can adjust like a volume knob to control the amountof light they let through. Cameras have three ways to control exposure,aperture, shutter speed, and ISO. This filter effectively becomes a fourthcontrol tool to manipulate light exposure. It controls the amount of light thatenters your lens by opposing two polarised filters. Rotating one creates adarkening effect, which ranges in influence from 3 to 7 f-stops of lightreduction. By reducing the amount of light entering the lens and sensor, aphotographer can create several awesome visual image effects. These effectswould not be possible in bright light conditions without a variable ND. Simplyadding the filter to the lens gains you your first 3 f-stops of light reduction.If you have ever visited a beach, desert or salt flats you will know how muchyou appreciated having sunglasses with you. Under those extreme lightingconditions you camera sits with all its exposure controlling settings toppedout. The amount of artistic control you can take becomes limited by therestriction of all values being maxed. Adding dialable "sunglasses" to yourcamera reopens creative possibilities.The Nano-X Series of FiltersK&F Concept's Nano-X Series of filters are crafted for the demands of UHDcapture. When you want 8k resolutions, use a filter that is designed foruncompromising quality. The filter is crafted from high precision Japaneseoptical glass. The lens is treated with a double-sided polishing process whichensures high-definition image quality at up to 8k. The filter also undergoes adouble-sided multilayer coating process where 28 layers is applied to the lens.Coatings effectively reduce reflections, increase effective light transmittancethrough the filter and avoids ghosting. The outer layer coating is hydrophobicto help repel water and are scratch resistant ensuring the longevity of yourfilter. The filter glass is larger than the threaded mount to further helpreduce vignetting, even when using a wide-angle lens. It also helps give afilter effect which is consistent over the entire frame.The Dark XThrough the polarisation mechanic used by Variable ND filters it is possible toform a dark X cross shape across the frame when dialled in at the extreme limitof the darkening effect. This filter does not suffer from the dark X effect. Ifyou have ever been caught with unusable images or video due to this phenomenon,then you will really appreciate this model. If your specific needs are for aVariable ND filter free of the dark X cross, consider the K&F ND8-ND128 which isa 3-7 stop filter and is free of this effect.Utilizing a Variable ND filter like this K&F model offers several advantages forphotographers and videographers. By slowing the shutter and extending exposuretimes, you can achieve a captivating motion blur effect, effectively contrastingstatic and moving subjects in your images. Additionally, the filter allows for ashallow depth of field, enabling the isolation of the main subject with a softblur in the background. For videographers, the Variable ND filter providesconvenient aperture control, often absent in many lenses. This feature provesvaluable for achieving a cinematic style in video creation. Moreover, thefilter's versatility streamlines gear and minimizes time spent swapping filters,making it an ideal all-in-one solution for photographers on the go.How to set it up and use itPlease verify your camera's lens thread size before ordering. Your camera's lensthread size will be marked somewhere on the lens barrel or printed underneathyour lens cap. This number is always preceded by the symbol for diameter. Whenyou match your lens diameter to the correct K&F Magnetic Variable ND Filter youscrew on the supplied magnetic adaptor ring. This ring houses magnets allowingthe VND filter to attach and hold in place. You are still able to rotate thefilter so you can control the extent of the darkening effect. There is amagnetic lens cap available as an accessory which means you can protect yourfilter or lens without having to remove all the parts first. The lens cap can beuse on the adaptor ring or with the filter still in place. Most filter damagehappens while trying to get them on or off your lens.
