Sandmarc launches hybrid polarized ND filters for DSLR and mirrorless cameras

20 Oct

Back in August photographic filter maker Sandmarc launched a line of hybrid polarized ND filters for smartphone cameras. Now the same type of filter has been released for DSLRs and mirrorless cameras.

Like the smartphone equivalent, the Hybrid Pro filter series combines the filter attributes of neutral density (ND) and polarizers into one single filter. Like a ND filter they help improve dynamic range of a shot in bright light, can help add motion blur to moving objects by allowing for slower shutter speeds, and offer more control over exposure and shutter speeds for film makers. Like a polarizer, they also help reduce reflections, protect highlights and boost color.

Sandmarc’s Hybrid Pro filters are made from multi-coated and anti-reflective glass for accurate color transmission. The company says the aluminum frame material makes the filters both durable and lightweight.

A set of filters includes ND16/PL, ND32/PL and ND64/PL variants to cover shooting in a range of light conditions. The filters are available in 58, 67, 77 and 82mm diameters and can be pre-ordered on the Sandmarc website now. Pricing starts at $ 169.99 for the 58mm version.
