The new VFFOTO magnetic system uses a thin adapter, screwed on the end of the lens, and special photo filter in a magnetic frame, which is mounted to the adapter by simply attaching it.
Magnetic filters as an alternative to screw-on photo filters are quick and easy to replace. Just bring the filter close to the adapter at the end of the lens and it holds firmly immediately. You can take it off just as easily. The solution is perfect for everyone who has a problem with perpetual screwing when changing filters.
This magnetic system is not compatible with "classic" screw-on VFFOTO filters.
What makes VFFOTO magnetic filters so unique? Simplicity. Instead of two adapters in similar systems (one at the end of the lens, the other on a regular photographic filter), the VFFOTO's counterpart to the adapter is the photographic filter. Or even several, because they can be layered on top of each other and have several filters applied at the same time (for example, polarizing together with ND). With the attached magnetic filters, it is possible to use the original lens hood supplied by the lens manufacturer without any problems.
The new magnetic filters cannot be combined with the existing screw-on filters, it is a different system. We will be producing both versions of the filters in parallel and our customers will always be able to choose whether they prefer screw-on or magnetic filters.
The ND (neutral density) filter reduces light of all wavelengths (colors). By using an ND filter, the photographer can extend the exposure time, change the aperture according to his priorities, and control the length of exposure even in extreme conditions (sea, mountains, snow).
Please note, cheaper ND filters do not reduce the light intensity of all wavelengths evenly, which can cause color defects in the image.
VFFOTO ND filters GOLDEN SERIES are are developed, designed and assembled in the Czech Republic. The components are manufactured in China.
They have 14 anti-reflective layers (7 on each side), and also new 3+3 nano layers with the most advanced features: increased scratch, water and grease resistance and easier cleaning.
The ND filters in this series are primarily designed for digital cameras, but can also be used on conventional film SLRs.
This filter can also be used on ultra-wide lenses (including zooms) with focal lengths of 15 mm and above (FF), 82 mm and smaller, see the following "Help sheet”.

VFFOTO MAGNETIC 4.5 ND FILTER GS - in extetior:
Why choose the VFFOTO MAGNETIC 4.5 ND FILTER GS:
1. very simple and fast change of filter without screwing,
2. 14 (7+7) high quality anti-reflective layers = minimizing of unwanted reflections,
3. final surface treatment of the filter with nano layers = resistance against water, scratches and dirt, easy cleaning, these layers improve the mechanical and physical properties of the glass,
4. original, quality optical glass = not affecting sharpness, preserves finest details,
5. relatively small color shift = these filters can be used with excellent results in black & white and color photography,
6. for a wide focal range of 24-800mm (converted to full frame) = versatile use, suitable for use on all lenses from wide-angle (24mm on full frame and above) to telephoto (800mm),
7. special hydrophobic treatment means that the water droplets do not spill but form balls instead = the droplet slides on its own or it is possible to remove it with an air blower, for example, a single drop of water will not degrade the image that took tens of seconds or even minutes to take,
8. glass filter does not generate static electricity = does not attract dust (unlike plastic/resin filters)
9. excellent value for money = satisfied and returning customers,
10. processed with precision = reliability,
11. the possibility of replacing the glass if it is damaged,
12. 10 years warranty - output control of every filter is performed in the Czech Republic.
VFFOTO recommendations:
We recommend the VFFOTO GS series magnetic ND filters for those looking for quality without compromise and, at the same time, fast and easy filter handling. It is suitable for the best lenses with a focal length of 24-800 mm (converted to full frame), and also on ultra-wide angle lenses with a focal length of 15 mm (FF) and a lens diameter of 82 mm and smaller from such companies as Canon, Nikon, Carl-Zeiss, Leica, Hasselblad, Olympus, Pentax, Fuji, Sony.

VFFOTO MAGNETIC 95 MM 4.5 ND FILTER GS – simple, fast, no screwing!
Technologie VFFOTO NanoShield představuje pokročilou high-tech úpravu foto filtrů pomocí ultra tenkých nano vrstev, které výrazně omezují ulpívání vody, mastnoty i běžných nečistot. Díky speciální hydrofobní a oleofobní ochraně zůstává povrch filtru déle čistý, kapky vody snadno stékají, prach se méně zachytává a otisky prstů lze odstranit jediným setřením.
Technologie VFFOTO GlareShield 14 využívá systém 14 kvalitních antireflexních vrstev — 7 vrstev z každé strany filtru — které pomáhají redukovat nežádoucí odlesky a ztrátu kontrastu při fotografování. Vícenásobný multicoating zvyšuje propustnost světla a přispívá k čistšímu obrazu, věrnějším barvám a lepší kresbě detailů.
Technologie VFFOTO TrueColour byla vyvinuta s jediným cílem — zachovat maximálně přirozené podání barev bez nežádoucího barevného posunu při použití filtrů. Díky pečlivě vybraným optickým materiálům, prémiovým polarizačním fóliím a přesně laděným ND coatingům dosahují filtry s označením VFFOTO TrueColour mimořádně neutrální barevné charakteristiky napříč celým viditelným spektrem.
Technologie VFFOTO PureVision 12K byla vyvinuta pro maximální zachování obrazových detailů i při použití na nejmodernějších fotoaparátech a špičkových teleobjektivech s extrémním rozlišením. Díky mimořádně vysoké optické transparentnosti až 99,9 % prochází filtrem prakticky veškeré dopadající světlo bez negativního vlivu na ostrost, kontrast nebo mikrokresbu obrazu.
