Heliopan SH-PMC Circular Polarising High Transmission filter is available in Standard and Slim versions. Not all filter sizes are available as Slim type.
Slim type has no front filter thread so a lens hood or lens cap cannot be used but is about 1.5mm to 2mm thinner.
Heliopan’s SH-PMC (Multi-Coated) High Transmission Circular Polariser allow the highest passing of light. Confounding the expectation that up to 2.5x stop may be lost when using a polariser, the high transmission versions reduce light loss by 0.5x. For users who value every bit of light, for low light photography, architectural and interior work, it’s a real benefit.
Heliopan’s remarkable 8 layer multi-coating uses metallic oxide coatings and enhances anti-reflection capabilities passing through a astonishing 99.8% of the light. It also protects the glass with it’s hard scratch protective surface. Plus it’s coated on both sides of the filter!
Ideal for photographers who shoot landscapes, you will find this filter is excellent when it comes to enhancing the blue of the sky as well as making the clouds more distinct. On water, you’ll use it to eliminate reflections. Multi-coated protection allows you to easily clean this filter’s glass surface.
The Heliopan SH-PMC Circular Polariser High Transmission is also unique in design since its black brass filter ring is indexed so that if you’re not using a traditional SLR, you’ll be able to set the rotating ring to a precise setting each time you wish to achieve the same degree of polarisation. The brass composition of the filter ring also prevents jamming when placing or removing it.
