How to clean VFFOTO filters?
First remove any dirt with an air blower to prevent scratching the surface. Gently clean any remaining dust or fingerprints with a lens pen or a high-quality microfiber cloth. For heavier contamination, use a special cleaning fluid designed for optics — apply it to the cloth, never directly to the filter. Avoid paper tissues and rough materials, as they may damage the anti-reflective coatings.
How are VFFOTO filters packaged and stored?

VFFOTO filters are packed in an original polystyrene calibration box, which ensures safe storage and protects the filter during transport and storage. The box is designed for easy opening and closing, so the filter is quickly accessible while remaining safely stored.

UV-PROTECTOR filters

What is the difference between a UV filter and a UV-PROTECTOR filter?

With VFFOTO, the difference is clearly defined by the level of protection and the effectiveness of UV radiation blocking:

UV filter

  • Standard level of lens protection
  • Lower reduction of UV radiation
  • Primarily serves as a basic filter with a slight optical benefit
  • Suitable for less demanding conditions

UV-PROTECTOR (L41, NANO-PRO 12K)

  • Significantly higher protection of the front lens element
  • 0% UV light transmission, providing full UV blocking
  • Maximum haze reduction while preserving contrast
  • Designed as a premium protective solution with no impact on sharpness

One-sentence summary

UV filter = basic protection + partial UV reduction
UV-PROTECTOR = maximum protection + full UV radiation blocking

In practice:
The VFFOTO UV-PROTECTOR is not just “protective glass”, but a technologically advanced filter that combines the highest level of lens protection with maximum optical image clarity.

What does the L41 designation mean for UV-PROTECTOR filters, and how does it affect the final photograph?

The L41 designation used for UV filters refers to a specific type of UV blocking that begins at approximately the 410 nm wavelength.

What this means in practice:
An L41 filter effectively removes unwanted ultraviolet radiation that can negatively affect image quality, especially in scenes with a high proportion of UV light, such as mountains, the sea, and distant landscapes.

How it affects the final photograph:

  • Higher image clarity – reduction of bluish haze in distant views
  • Better contrast – images appear cleaner and less greyed out
  • More accurate colour rendering – elimination of colour shifts caused by UV radiation
  • Maximum sharpness preservation – a high-quality L41 filter, such as NANO-PRO 12K, has no negative impact on image detail

Important:
Unlike cheap UV filters that can degrade the image, a high-quality L41 UV filter is designed to improve image quality without compromise, meaning without any loss of detail, contrast, or sharpness.

Simply put:
L41 = precisely defined UV protection that helps achieve a cleaner and more contrast-rich image, especially in demanding lighting conditions.

How can I achieve a cinematic look in my photos?
A cinematic look can be achieved by using a Black Mist filter, which gently softens contrast, creates a subtle glow around light sources and reduces the overly sharp digital appearance of the image. The result is a softer, more atmospheric photograph with more natural-looking highlights.

ND filters

V této kategorii zatím nejsou žádné otázky.

ND 2000x

What is the VFFOTO ND 2000× filter used for?

The filter reduces the amount of light passing through the lens, allowing significantly longer exposure times even in daylight. Use it to smooth water surfaces, create a soft blur in flowing water, or capture the movement of clouds.

How much does the ND 2000× filter extend the exposure time?

The filter reduces light by approximately 11 stops. With the aperture and ISO unchanged, it extends the exposure time by approximately 2,000 times. For example, an exposure of 1/125 second without the filter becomes approximately 16 seconds with it. An exposure of 1/30 second becomes approximately 67 seconds.

How do I take photographs with the ND 2000× filter?

Mount your camera on a stable tripod. First, compose the image, focus, and determine the exposure time without the filter. Then switch to manual focus, attach the filter, and set the calculated exposure time. For longer exposures, use Bulb or Time mode, depending on your camera’s capabilities. The VFFOTO ND Calculator can also help you determine the exposure time.

Is it better to stop down the aperture or use a strong ND filter for a long exposure?

A strong ND filter allows you to extend the exposure time while keeping an aperture suitable for the desired depth of field and lens sharpness. This avoids using the smallest apertures, where diffraction can reduce image sharpness. Choose the aperture to suit the scene, then use the filter to adjust the exposure time.

Why does a photograph taken with a strong ND filter have different brightness or a colour cast?

Lighting conditions may change during a long exposure, and automatic white balance may respond differently than it does without the filter. Light entering the camera through openings other than the lens can also affect the result. Shoot in RAW, check the histogram after the first image, and adjust the exposure time if necessary. If you use a DSLR, cover the optical viewfinder.

Can I use the ND 2000× filter to photograph the Sun?

The VFFOTO ND 2000× is not a solar filter. We strongly advise against viewing a solar eclipse through this filter with the naked eye or through a camera’s optical viewfinder.

Based on VFFOTO’s experience, we have no recorded cases of camera sensor damage when photographing solar eclipses with this filter since 2012. However, this experience does not guarantee safety for every camera or method of use.

VND filters

What is a variable ND filter, and what is it used for?
A variable ND filter allows you to smoothly control the amount of light entering the lens. By rotating the front ring of the filter, you can quickly adjust its effect without having to change filters. It is primarily used for video recording, shooting with a wide aperture, and extending exposure times.
 
What range does a VND 2–32× filter offer?
The 2–32× range corresponds to a light reduction of 1 to 5 stops. The lowest setting lets in the most light, while the highest setting allows you to take photos or record videos in much brighter conditions.
 
What is the difference between a VND filter and a fixed ND filter?

A fixed ND filter has only one level of light reduction. A VND filter offers a continuously adjustable range, allowing you to respond quickly to changing light conditions. Fixed ND filters are generally more suitable for long exposures, while VND filters provide greater convenience when recording video and working in changing light conditions.

When combined with an add-on filter, VND filters can also be used for long and very long exposures.

Can a VND filter affect colours or image quality?

Every VND filter works using two polarising layers, which means that low-quality filters may cause colour shifts or uneven darkening across the image. VFFOTO VND filters with True Colour technology are designed to preserve natural colour rendition, good contrast, and fine details.

Can the range of hybrid VND filters be extended further?

Yes. A compatible add-on filter can be attached to the VND filter to increase the overall light reduction of the entire optical system. For example, combining a VND 2-32x filter with an ND 8x add-on filter creates a resulting range of ND 16-256x. Use only combinations recommended or verified by VFFOTO.

Is a VND filter suitable for photographing a solar eclipse?
It is not.
Which add-on filters can I use with a VND filter?

VFFOTO VND filters can be used with compatible VFFOTO ND 8x, ND 512x and ND 1000x add-on filters. The resulting range is calculated by multiplying the strength of both filters:

VND 2-32x + ND 8x = ND 16-256x
VND 2-32x + ND 512x = ND 1024-16384x
VND 2-32x + ND 1000x = ND 2000-32000x

The ND 8x filter is suitable for extending exposure times in everyday situations, while the ND 512x and ND 1000x filters allow you to work with long and very long exposure times.

Can a magnetic filter be used together with a hybrid VND filter?

Yes. A hybrid VND filter can be mounted on the lens either by screwing it in or magnetically. VFFOTO magnetic filters can then be attached to its front side; their nominal diameter must be two standard sizes larger than the VND filter’s rear mounting diameter.

Black Mist filters

What is a Black Mist filter used for?
The filter is particularly suitable for portrait, wedding, lifestyle and night photography, video recording, shooting against the light and photographing scenes with prominent light sources. It also works well for city photography, concerts and interiors.
What effect does a Black Mist filter create?
The Black Mist filter gently diffuses prominent light sources, softens high contrast and creates a subtle glow around highlights. At the same time, it slightly smooths skin tones and reduces the overly sharp digital look of the image without significantly reducing the amount of captured detail.
What is the difference between Black Mist 1/8, 1/4 and 1/2 intensities?
The individual versions differ in the intensity of the resulting effect. Black Mist 1/8 provides very subtle softening suitable for general use. The 1/4 version creates a more noticeable glow and softer contrast. Black Mist 1/2 produces the strongest effect and is particularly suitable for highly atmospheric photography and video.
Does the Black Mist filter affect image sharpness and colour rendition?
The filter intentionally softens highlights and overall contrast, but when the appropriate intensity is selected, it preserves important image details. High-quality optical glass and anti-reflective coatings help maintain natural colour rendition without a significant colour shift.
Can the Black Mist filter be combined with other VFFOTO filters?
Yes. The Black Mist filter can be combined with VFFOTO polarising, ND or VND filters. However, when stacking multiple filters, you need to account for the increased overall height of the filter assembly and check for possible vignetting when using wide-angle lenses.

White mist filters

What is a White mist filter and how does tt affect a photograph?
A White Mist filter is a diffusion effect filter that softens the image, reduces overall contrast and creates a subtle glow around highlights. It gives photographs and videos a softer, more atmospheric look.
What is the difference between the White mist D 1/8, 1/4, 1/2, and 1/1 strengths?
The 1/8 strength provides very subtle softening, 1/4 delivers a balanced effect, and 1/2 creates pronounced diffusion. White Mist D 1/1 is the strongest version, providing intense image softening and a distinctive glow around light sources.
What types of photography are White mist filters suitable for?
White Mist filters are ideal for portraits, weddings, urban scenes, concerts, and night photography. They also work very well for video, giving footage a more cinematic and less clinical look.
Can a White mist filter be used in daylight?
Yes. In daylight, the filter softens harsh light, skin tones, and strong contrasts. However, its effect is most noticeable when shooting against the light or in scenes containing bright light sources.
What is the difference between White mist and Black mist filters?
White Mist creates a brighter, softer, and more dreamlike image. Black Mist also softens highlights and fine details but generally preserves the depth of darker areas and the overall contrast of the scene more effectively.

VFFOTO hybrid adapters

What is the VFFOTO hybrid adapter used for?
The VFFOTO hybrid adapter screws into the lens thread and creates a magnetic base for quickly attaching VFFOTO filters. This means you do not have to screw the filter into the lens every time you use it. Simply place the filter onto the adapter, the magnetic system seats it in position, and you can start shooting.
Does the VFFOTO hybrid adapter affect the final photograph?
No. The VFFOTO hybrid adapter contains no optical glass, so it does not affect the sharpness, colours or contrast of the final photograph. It serves only as a precise mechanical and magnetic base for attaching the filter.
Is the VFFOTO hybrid adapter compatible with filters from other manufacturers?
Compatibility with magnetic systems from other manufacturers cannot be guaranteed. Each manufacturer may use a different construction, magnetic strength, dimensions or attachment method. The VFFOTO hybrid adapter is intended primarily for VFFOTO magnetic and hybrid filters.

Step-up rings

What is the VFFOTO STRONG Magnetic Step-Up Ring used for?
It allows you to use larger-diameter VFFOTO magnetic and hybrid filters on a lens with a smaller filter thread. For example, a 72–82 mm step-up ring allows you to attach 82 mm filters to a lens with a 72 mm thread.
Which filters are compatible with the STRONG Magnetic Step-Up Ring?
It is compatible with all VFFOTO magnetic and hybrid filters of the corresponding output diameter. For example, the 72–82 mm step-up ring can be used with all 82 mm VFFOTO magnetic and hybrid filters.
What is the difference between a step-up ring and a magnetic adapter?
A magnetic adapter keeps the lens and filter diameter the same. A step-up ring changes the diameter while also creating a magnetic base for attaching a larger filter
Why should I use filters with a larger diameter than my lens thread?
Using different step-up rings allows you to use one larger filter on several lenses with different thread sizes. This means you do not need to purchase the same type of filter in several diameters. A larger filter diameter may also help reduce the risk of vignetting when stacking multiple filters.
Is the STRONG Magnetic Step-Up Ring suitable for heavier filters?
Yes. The reinforced STRONG magnetic system is designed to securely hold standard VFFOTO magnetic and hybrid filters, including heavier VND filters. Before taking photographs, always make sure that the step-up ring is properly tightened and that the filter is seated securely around the entire circumference.

GOLD MIST

What is a Gold Mist filter and what does it do?
Gold Mist is a diffusion filter for photography and video. It softens bright highlights, reduces contrast and creates a warm, golden glow around light sources. This gives the image a softer, warmer atmosphere directly in camera.
What is the difference between Gold Mist, White Mist and Black Mist filters?
Gold Mist creates a warm, golden glow around lights. White Mist produces a whiter glow and a brighter, dreamier look. Black Mist also softens highlights but generally preserves more depth in the darker areas of the image. The choice depends on the atmosphere you want to create.
What is the difference between Gold Mist 1/4 and 1/2 strengths?
The 1/4 strength offers subtler softening and a balanced golden glow for a wider range of uses. The 1/2 strength produces more pronounced diffusion, a stronger glow around lights and a greater reduction in contrast. With both versions, the visibility of the effect also depends on the lighting and contrast in the scene, particularly the presence of bright light sources.
What types of photography and video are Gold Mist filters suitable for?
Gold Mist filters are suitable for portraits, weddings, evening city scenes, concerts and atmospheric video. Their effect is particularly noticeable in backlit scenes and around street lamps, candles or car lights. They work well whenever you want to soften highlights and give the scene a warm feel.
Can a Gold Mist filter be used in daylight?
Yes. In daylight, it softens harsh light and contrast, particularly when shooting into the light. Its effect tends to be less noticeable in soft, even lighting. Choose the 1/4 strength for a subtler result or the 1/2 version for a more pronounced atmosphere.
Can a hybrid Gold Mist filter be combined with other VFFOTO filters?
Yes. A hybrid Gold Mist filter can be combined with compatible VFFOTO hybrid and magnetic filters, such as a polarising or ND filter. The diameters of the magnetic connection must match. When using it with a variable ND filter, follow that filter’s front diameter, which may be larger than the lens thread. When stacking filters on wide-angle lenses, check for possible vignetting.
