X2 CPL (Circular Polarizer) FILTER: The X2 CPL filter features critically sharp AGC glass made in Japan. Resolving critically sharp and delivering excellent color neutrality, the X2 CPL features an ultra-slim frame profile, MRC8 and durable weather-sealed construction.

MRC8 CREDIT FILTER: Uniformly applied MRC8 to eliminate unwanted glare and ghosting which easily get’s compounded at long exposures. Our MRC8 is structurally harder than the glass itself, providing a protective scratch-resistant layer, shielding the glass from the elements of frequent fieldwork.

NANOTEC: In addition to state-of-the-art MRC8, our optical engineers developed new nano coating layer technology, called nanotec, from the ground up to repel dirt, water and other elements by beading rather than absorbing and smearing. Set in our completely weather-sealed X2 traction frame the X2 CPL was built to withstand the harshest of environmental conditions.

AGC GLASS MADE IN JAPAN: The X1 UV features 4-layers of our state-of-the-art and uniformly applied MRC coatings which reduces flaring and ghosting than you’d normally see with uncoated protection filters

ELIMINATES VIGNETTING: An ultra-slim, double-threaded design that eliminates vignetting on wide-angle full-frame setups

WEATHER-SEALED DURABILITY: Every filter we make, including the X1 UV, is weather-sealed to ensure that your lens is protected against the elements

MRC8 CREDIT FILTER: Uniformly applied MRC8 to eliminate unwanted glare and ghosting which easily get’s compounded at long exposures. Our MRC8 is structurally harder than the glass itself, providing a protective scratch-resistant layer, shielding the glass from the elements of frequent fieldwork.

X2 ND (NEUTRAL DENSITY) FILTER: Our X2 ND 3-stop features critically sharp H-K9L optical glass made in Japan. The moment you pick up X2 ND you’ll immediately feel the craftsmanship and quality. We precisely machine each X2 traction frame from environmentally friendly aluminum, and with it’s matte black finish reflections are absorbed rather than reflected into the lens barrel.

NANOTEC: In addition to state-of-the-art MRC8, our optical engineers developed new nano coating layer technology, called nanotec, from the ground up to repel dirt, water and other elements by beading rather than absorbing and smearing. Set in our completely weather-sealed X2 traction frame the X2 ND was built to withstand the harshest of environmental conditions.

ELIMINATES VIBRATION: X2 features an ultra-thin 3.5mm double-thread traction frame to remove vignetting in full-frame, wide-angle configurations. In our laboratory tests, 4.3 mm was the width of the frame in which vignetting is noted in 16 mm wide-angle configurations in full-frame configurations. Any less than 3.0 mm and lens caps do not have enough surface to grip. The 3.7 mm vignetting is completely eliminated.

NANOTEC: In addition to state-of-the-art MRC8, our optical engineers developed new nano-coating layer technology, called nanotec, from the ground up to repel dirt, water and other elements by beading rather than absorbing and smearing.

WORLDS MOST COLOR NEUTRAL POLARIZER, GUARANTEED: A perfectly flat transmission curve would yield a perfectly color neutral result, and while there is no such thing as a perfectly neutral CPL filter (contrary to what other filter makers may claim) the X4 CPL is the most color neutral any CPL filter, guaranteed.

WORLDS MOST ADVANCED POLARIZER: All commercially available CPL filters exhibit a yellow cast due to a gradual transmission increase starting around 600nm and then spiking at 650nm onward into IR. With our X4 CPL film we achieved a gradual transmission decrease from 600nm onward, and instead of spiking uncontrollably near 650nm and far into infrared, the X4 CPL sees very controlled transmission into IR, without the curve spike. Result: Warm and lively images without the apparent colorcast.

X4 CPL (CIRCULAR POLARIZER) FILTER: The X4 CPL features SCHOTT Superwhite B270(R) optical glass, which is an ultra clear crown glass. It is produced by melting high purity raw materials and then made using the continuous draw process. The result is excellent transmission in the ultraviolet, visible, and infrared spectrums, and a high surface quality that accepts our state-of-the-art MRC and nanotec(R) coatings exceptionally well.

MRC8 CREDIT FILTER: Uniformly applied MRC8 to eliminate unwanted glare and ghosting which easily get’s compounded at long exposures. Our MRC8 is structurally harder than the glass itself, providing a protective scratch-resistant layer, shielding the glass from the elements of frequent fieldwork.
