There are generally two types of ND filters you can buy: circular filters that screw on to the front of your lens or a square filter that mounts via an adapter. Let’s take a look at the pros and cons of both.

In video shooting, it is fundamental to keep the shutter speed fitting the frame rate setting. That is, to keep it equal to double the frame rate for optimal results. This is because, unlike still photography, an excessively fast shutter speed may create a jarring effect and produce afterimages that will not look good in the final video. A slight textured edge to the front element makes adjustment easy, and there are clear markings between the minimum and maximum points. While there are different kinds of ND Filter, the Variable ND Filter seems to be the most outstanding one. Rotating to the maximum marker (eight stops) creates a dark X, but ease off and you can extend your exposure times by six stops (taking a 1/60 sec exposure up to a full second) and still get usable images.You now have an arsenal of the best variable ND filters at your fingertips. You may be considering the size of your lenses, or you may be considering the place in which the glass is made. In short, a fixed ND filter will deliver higher quality images, while a variable ND filter offers far more speed, flexibility and convenience. A variable ND filter will also save you a lot more money in the long run than buying lots of fixed ND filters at different strengths. Is a variable ND filter a polarizer?

Made with nano coating layer technology. The nanotec repels dirt, water, and elements while shooting. There are, however, some subtle differences in image quality between variable ND filters and traditional fixed ND filters. Customers like you enjoy this best variable ND filter because of its superiority in the market. Vloggers especially love the good variable density. Avariable ND filter may present its density range as ‘ND2-ND400’. At ND2 you’ll get a one-stop reduction in light transfer, and at the ND400 position, there’llbe an eight-stop reduction.Variable ND filters are used for two purposes. Firstly for cinematography when the light is too bright to record at the correct frame rate and secondly in stills photography they are used to slow the shutter down. This might be to create a long exposure for moving clouds or water. The variable nature denotes the amount of stops of light the filter will reduce. These will change by rotating the filter on the end of the lens where it is threaded. The practical exposure range and light transmittance will vary depending on the situation. When using the filter near or at MAX a cross-like dark pattern will appear across the image and cannot be eliminated. This is a property of the filter and all variable ND filters. This best variable ND filter is the Hoya 77mm variable density screw-in filter. This filter is known for its superiority for a few reasons. Features & Specifications The filter is said to provide between one and five stops of light reduction, which we found to be accurate, but expect uneven light transfer beyond around three stops of reduction.

High-quality glass with some subtle but clever design features make this large 95mm variable ND filter from Haida an ideal choice for filmmakers and photographers. As with all variable NDs, there is a slight colour cast, but this is easily corrected. The benefits of being able to adjust exposure without dipping into your camera settings is worth the small colour cast sacrifice. One important thing you should have in mind is not going beyond any of these levels as that can cause interference that would lead to an exposure variation. The final results may not be very encouraging if that happens. This variable ND will cost you plenty, but its durability and consistent colours all throughout its different density settings will give your images a reliable style and feel.Variable ND filters come in a range of sizes and price points. To help you choose, we’ve rounded up seven of the best variable ND filters for your needs, from the high end to the budget options. The 67mm Small Kit comes with adapter rings that allow you to mount the filter to lenses ranging from 52mm to 58mm. The 82mm Large Kit option provides adapters for lenses from 72mm to 77mm. While variable ND filters offer tons of flexibility, sometimes you can push them too far. You’ll know when you’ve done this if you see a funny dark cross in the centre of your scene if you try to darken the image too much – this is a feature of using two sheets of polarising material. And if you use them with a very wide lens there can be variation in the effect across the frame.
