"UW Variable Red Filter M67" which provides seamless filter strength adjustment to accommodate with different depth to avoid underwater blue cast (*1)


  • Consists of two polarizing filters to reduce green and blue wavelengths enabling to achieve photo/video with less blue cast (*2)
  • Turning front polarizing filter provides seamless adjustment of filter strength from almost none-filter effect to maximum filter strength with nearly zero blue/green wavelengths. So this product effectively works to adjust color of your photos or clips from bright surface where we have rich ambient light not requiring a filter to the depth requiring strong filter effect due to less orange/yellow wavelength in ambient light (*2).
  • Two filters are combined by bayonet system for easy and speedy separation when necessary as like to eliminate trapped bubbles in between underwater or clean inside of the product after use without conducting complicated procedures.
  • Compatible with versatile "M67 Mount" to adopt to wide range of camera system. (*3)


Patent pending in Japan.


When using this product with stronger filter effect reducing blue/green wavelength significantly and

using external strobe/light will have reddish results. If you shoot with an external lighting device, set

minimum filter strength or remove this product from your camera system.


Depending on combined camera/housing, an image may have vignetting. If this happens, zoom in
