This filter features two key differences from the PRO nano HUC version.
- The ring is made from a titanium alloy and is thus stronger, lighter and less likely to get jammed in a lens thread.
- The popularity of the Landscape Enhanced polariser first made for the V5/100mm system has resulted in a circular version being brought to market. What's the difference? It has a stronger effect and a slightly cool tone. This filter works miracles for seascapes and scenes with water as it reveals more of the water by cutting through the surface reflections and it also ensures that all the whites in waves and cascades are a beautiful crisp, cool white.
When it comes to enhancing images, a circular polarizer is probably the oldest trick in the book. It can change a pale sky to a deep blue one, turn foliage into a luminous super-green, light up autumn colours, saturate rainbows and even make water look crystal clear. The added contrast, saturation and clarity that a polarizer can give to images is nothing short of magic and every photographer should have one in their bag.
Contrary to its name, a polarising filter does not polarise light; it filters out polarised light. Light from the sun is polarised when it bounces off any non-metallic reflective surface like water, foliage or various air particulates. Polarised light robs images of colour, clarity and contrast and is in many situations undesirable. A polarizing filter removes this 'damaged' light and ensures that only unpolarised light reaches the camera sensor to produce a sharp, saturated and contrast-rich image.
For this reason, a polarizing filter is a very popular tool for any photographer, but especially for landscape photographers.
NiSi's PRO Nano HUC polarisers are made from top of the range optical pro glass, mounted in a titanium alloy ring and treated with a cutting edge water-repellant and scratch-resistant nano-coating. Brass threads don't jam nearly as easily aluminium.
What is the difference between a linear and circular polariser? Digital cameras' AF systems are not compatible with linear polarizers. When the world was transitioning from film to digital, linear vs. circular was a big debate, but it no longer is. For photographic purposes, you can assume that any polariser on the market nowadays is circular and not linear.
