8+ Best Variable ND Filters for the Ultimate Exposure Control

A variable neutral density (ND) filter is a type of camera filter that reduces the amount of light entering the lens, allowing for greater control over exposure and depth of field. Unlike fixed ND filters, which have a set level of light reduction, variable ND filters allow the user to adjust the amount of light reduction, making them suitable for a wider range of shooting conditions.

Variable ND filters are particularly useful in situations where the lighting conditions are changing rapidly, such as when shooting outdoors on a sunny day. They can also be used to create creative effects, such as blurring motion or creating a shallow depth of field. Variable ND filters are typically made of high-quality optical glass and feature a rotating ring that allows the user to adjust the amount of light reduction. They are available in a variety of sizes and can be attached to the front of the lens using a filter adapter ring.

Variable ND filters are an essential tool for any photographer who wants to have greater control over their exposure and depth of field. They are relatively inexpensive and easy to use, making them a great option for both amateur and professional photographers alike.

1. Size

The size of a variable ND filter is an important consideration because it determines whether or not the filter will fit your lens. If the filter is too small, it will not cover the entire lens, and light will leak around the edges. This can cause vignetting, which is a darkening of the corners of the image. If the filter is too large, it will be difficult to attach and remove, and it may also cause the lens to vignette.

To choose the correct size filter for your lens, you need to know the diameter of the lens. The diameter is usually printed on the front of the lens, or you can measure it using a ruler. Once you know the diameter of the lens, you can choose a filter that is the same size or slightly larger.

Using the correct size filter is important for getting the best possible image quality. A filter that is too small or too large can cause vignetting, which can degrade the image quality. By choosing the correct size filter, you can ensure that you get the best possible image quality from your variable ND filter.

Here are some additional tips for choosing the correct size variable ND filter:

If you are using a zoom lens, you will need to choose a filter that is large enough to cover the widest angle of view of the lens.
If you are using a filter on a lens with a built-in lens hood, you will need to choose a filter that is large enough to fit over the lens hood.
If you are using multiple filters on the same lens, you will need to choose filters that are all the same size.

By following these tips, you can choose the correct size variable ND filter for your lens and ensure that you get the best possible image quality.

2. Material

The material of a variable ND filter is an important consideration because it affects the image quality and durability of the filter. Glass filters are more expensive than resin filters, but they offer better image quality. Resin filters are less expensive, but they may not be as durable and can degrade the image quality.

Image Quality
Glass filters offer better image quality than resin filters because they have a higher refractive index. This means that glass filters bend light more than resin filters, which reduces chromatic aberration and other optical distortions. Chromatic aberration is a type of distortion that occurs when different colors of light are bent at different angles, resulting in a loss of sharpness and color fringing. Glass filters also have a lower dispersion, which means that they do not spread light out as much as resin filters. This results in a sharper image with better contrast.
Durability
Resin filters are less durable than glass filters. They are more susceptible to scratches and breakage, and they can also be affected by heat and UV radiation. Glass filters, on the other hand, are more resistant to scratches and breakage, and they are not affected by heat or UV radiation. This makes glass filters a better choice for photographers who need a durable filter that can withstand the rigors of everyday use.
Cost
Glass filters are more expensive than resin filters. This is because glass is a more expensive material to produce than resin. However, glass filters also offer better image quality and durability, so they are worth the extra cost for photographers who demand the best possible image quality.

Ultimately, the best variable ND filter for you depends on your individual needs and budget. If you need the best possible image quality, then a glass filter is the best choice. However, if you are on a budget or if you need a filter that is more durable, then a resin filter may be a better option.

3. Density range

The density range of a variable ND filter is an important factor to consider when choosing the best variable ND filter for your needs. The density range determines how much light the filter can block, which in turn affects the exposure of your images.

A wider density range gives you more flexibility in controlling the exposure of your images. For example, a variable ND filter with a density range of 2-5 stops can reduce the amount of light entering the lens by 2, 3, 4, or 5 stops. This allows you to shoot with a wider aperture or slower shutter speed, which can be useful for creating shallow depth of field or blurring motion.

If you are shooting in bright conditions, you will need a variable ND filter with a wider density range to reduce the amount of light entering the lens. Conversely, if you are shooting in low-light conditions, you may not need a variable ND filter with as wide a density range.

Here are some examples of how you can use a variable ND filter to control the exposure of your images:

To create a shallow depth of field, you can use a variable ND filter to reduce the amount of light entering the lens, which will allow you to shoot with a wider aperture.
To blur motion, you can use a variable ND filter to reduce the amount of light entering the lens, which will allow you to use a slower shutter speed.
To shoot in bright conditions, you can use a variable ND filter to reduce the amount of light entering the lens, which will allow you to shoot with a faster shutter speed.

Variable ND filters are a versatile tool that can be used to control the exposure of your images in a variety of situations. When choosing a variable ND filter, it is important to consider the density range of the filter and how you plan to use it.

4. Rotation

The ability to rotate the ring on a variable ND filter is an essential feature for any photographer who wants to have precise control over the amount of light entering the lens. By rotating the ring, you can adjust the density of the filter, which in turn affects the exposure of your images.

A smoothly rotating ring is important for two reasons. First, it allows you to make precise adjustments to the density of the filter. This is important for getting the correct exposure, especially when shooting in challenging lighting conditions. Second, a smoothly rotating ring makes it easy to use the filter in conjunction with other filters. For example, you can use a variable ND filter in combination with a polarizing filter or a graduated ND filter to create unique and creative effects.

When choosing a variable ND filter, it is important to look for a filter that has a rotating ring that is smooth and easy to use. This will help you to get the most out of your filter and to create beautiful, well-exposed images.

Here are some examples of how you can use the rotating ring on a variable ND filter to control the exposure of your images:

To create a shallow depth of field, you can rotate the ring to reduce the amount of light entering the lens, which will allow you to shoot with a wider aperture.
To blur motion, you can rotate the ring to reduce the amount of light entering the lens, which will allow you to use a slower shutter speed.
To shoot in bright conditions, you can rotate the ring to reduce the amount of light entering the lens, which will allow you to shoot with a faster shutter speed.

5. Durability

Durability is an important factor to consider when choosing a variable ND filter. A durable filter will be able to withstand the rigors of everyday use, including being dropped, knocked around, and exposed to the elements. This is especially important for photographers who travel frequently or who shoot in harsh conditions.
