B+W 52mm Circular Polarizer MRC Pro Glass Filter

* Highest possible polishing technique * World's best optical glass * New thinner Pro mount. No vignetting

Color:: Dark Gray

Color:: The color of the item.

Overview

Highly efficient standard circular polarizing filter for all cameras with beam splitters in the light paths of their TTL exposure meter and with autofocus lenses. Circular polarization has the same pictorial effect as linear polarization, but allows for proper exposure metering and/or autofocus distance settings.
B+W Polarizers increase color saturation and reduce reflections. The neutral gray color and plane parallel polarizer material guarantee optimal image results. High-quality optical glass ensures excellent pictorial quality. The filter factor varies according to how the filter is positioned in relation to the sun. Filter factor is between 2.3 and 2.8.

Detailed Specifications
Filter Type:	Circular Polarizing
Filter Type: The type of filter for a lens. Filters can be screwed on the front element or dropped in for larger zoom lens. View All Attribute Definitions
Multi-Coated:	Yes, MRC (Multi-Resistant Coating)
Multi-Coated: A series of optical coatings that are on a lens/filter that help reduce the impact of reflections. The result is a higher transmission percentage of light. All modern lenses are multi-coated. View All Attribute Definitions
Filter Construction:	Schott glass
Filter Construction: This is the construction of a type of filter. The type of process used to create a filter can affect its price. Filters can be constructed out of regular glass that sandwiches a coloured gel in between or in high-end filters, raw elements are added to the molten optical glass so there is no risk of uneven colour or fading.

Filter Diameter:	52mm
Filter Diameter: Almost every modern lens has a filter ring/thread on it for a UV filter. Filter Diameter refers to the size (diameter) of the front ring. There are several common sizes. View All Attribute Definitions
Rotating:	Yes
Rotating: Allows a rotating or pivoting action for a device such as a flash or lcd screen. View All Attribute Definitions
Filter Effect:	Eliminates reflections and haze and improves color and tonal saturation
Filter Effect: Allows various filter effects to be done in-camera while shooting. Common filter effects are vivid, neutral, sepia, black and white, negative, cooling, warming, etc... View All Attribute Definitions
Filter Factor:	About 2.5 (1.3 stops)
Filter Factor: When placed in the optical path, many filters block a certain amount of light from reaching the lens. Filter factor relates to how much exposure compensation is required in order to adjust for this. Most cameras have TTL metering and will be able to do this automatically.
