Lee Circular Polariser 105mm Rotating Glass Filter

The Lee Circular Polariser 105mm Rotating Glass Filter attaches to the Lee Filter Holder via the Lee 105mm Front Holder Ring (both not included, available separately). Ideal for landscape photography, this filter can remove potentially distracting reflections from non-metallic surfaces and has the effect of saturating colours and deepening blue skies.

Key Features: Lee Circular Polariser 105mm Filter

This Polariser is attached to the filter system by an Accessory Ring, which fits to the front of the Lee Filter Holder (both not included). This allows the Polariser to be rotated independently of any other filters in the holder. It is the ideal solution for landscape photography, where a combination of graduated filters and Polariser may be required.

Circular polariser filters are the ideal accessory for landscape photographers and are designed to remove potentially distracting reflections from non-metallic surfaces such as glass and water.

When used outside on sunny days, polarising filters have the effect of saturating colours and deepening blue skies. The change of effect can be seen through the lens of reflex cameras as the filter is rotated.

They can also be used in conjunction with other filters (although the polariser should always be placed in front of polyester filters to ensure it functions correctly). A polarising filter will increase your exposure by approx. 1.5-2 stops.

A Lee Filter Holder and 105mm Front Holder are Ring required.

Slimmer version also available

There is now a slimmer version of this filter available designed specially for landscape photographers using full-frame cameras and ultra-wide-angle lenses. View our product page for more details.

Why use a Polariser?

Polarising filters are used to manage light at wavelength scale, and if magnified could be a likened to a series of microscopic slats. In use, as the filter is rotated, it either transmits or blocks the waves of light that are vibrating in particular orientations. When light from the sun bounces off a flat non-metallic surface, such as glass or water, it becomes polarised - i.e. all of the reflected light waves vibrate in the same plane. This reflected glare can be removed by the polarising filter.

Rotation of the filter will be needed to find the optimum position of the Polariser. In photographic terms this can render water or glass transparent, and gives the impression of saturating colours in a scene, because much of the reflected glare from the subject is removed by the Polariser.

On a clear sunny day, much of the light in the sky is also polarised, and the filter will give a very strong blue effect when used at 90 degrees from the sun - any white clouds will stand out impressively.

Which Polariser - Linear or Circular?

There are two types of polarising filter: linear and circular. These terms do not refer to the shape of the filter, but rather the way in which the filter modifies the light waves that pass through it. The type of filter required depends on the camera. If you use an autofocus SLR (digital or 35mm) in, for example, spot metering mode, you will need a Circular Polariser. This is because a Linear Polariser will interfere with the complex metering and AF systems of modern cameras. If you use a manual focus camera, whether 35mm or medium format, you can use either a Circular or a Linear Polariser. If you are still unsure of the type of Polariser you require, check your camera's instruction manual.
