VFFOTO magnetic 77 mm polarizing filter GS L

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 easy and quick 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 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.
VFFOTO Filters GOLDEN SERIES of mark "L" (L for "Long" as for the long focal length of the lens) represent the best class of professional polarizing filters that we in VFFOTO can develop with the technology available in present.
These filters were primarily developed for use on lenses with long focal lengths, which place the absolute highest demands on the optical properties of the filter, the quality of the material and manufacturing.
VFFOTO GS L polarizing filters are universally applicable for all lenses from the shortest focal lengths to telephoto lenses.
They have 16 anti-reflective layers (8 on each side) against glare and for better contrast. The new 3+3 nano layers mean increased scratch and grease resistance, prevent water droplets from sticking and makes it easier to clean the filter. We only use premium materials (optical glass, Japanese polarizing film Nitto). The total thickness of the glass and polarizing film combined is only 1.2 mm ("less glass thickness = less optical defects"). A unique advantage is the perfect protection of the delicate polarizing film against the adverse effects of the environment. The film is stretched between the two glasses, airtight and sealed all around. This makes VFFOTO GS polarizing filters suitable for even the harshest weather conditions.

All VFFOTO GS L-series polarizing filters have premium polarizing film from the Japanese company Nitto and first-class optical glass Schott B270.
VFFOTO GS L polarizing filters can be used for any lens with the matching filter thread diameter on digital and conventional film cameras. As there is a possibility of vignetting on focal lengths of 15-24 mm (on full frame), it is better to have a larger diameter filter fitted through the magnetic step-up ring as per the instructions below. When using a polarizing filter on a wide-angle lens (below about 30 mm focal length on a full frame), the possibility of non-uniform polarization (a physical phenomenon with any polarizing filter, regardless of brand or manufacturer) must also be taken into account.

VFFOTO GOLDEN SERIES polarizing filters with L marking are developed, designed and assembled in Czech Republic. The output control of every filter is performed in Czech Republic, too. The production of the components itself is made to order in China.

This filter can also be used on ultra-wide lenses (including zoom lenses) with focal lengths of 15 mm and above (converted to FF), with a diameter of 67 mm and smaller, see "Help sheet".
