Product Description
Circular Polarizers - Increase Color Saturation, Reduce Reflections
B W Circular 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.
Exposure compensation is about two f-stops.

MRC - A Special Scratch-Resistant, Water and Dirt Repelling Coating
The MRC coating is first and foremost a broadband anti-reflection coating. This means that its reflection-reducing effect, which is thus also a transmission-increasing effect,
i.e. one which suppresses scattered light and ghost images and transmits more light, has a broadband action over the full spectrum. With the MRC coating,
the blue, violet and red to deep-red light cannot produce any contrast reducing scattered light, spotty reflections or ghost images.

The main advantage of MRC coating, is it's ability to combat flare and ghosting. Another benefit is that their filters remain free of dirt longer.
When necessary, it is a lot easier to wipe off the dirt with a blower brush, because of MRC's ability to repel dirt and moisture.
This also reduces the risk of micro-scratches which can occur during cleaning.

F-Pro Brass Filter Mount
This filter uses a rotating B W F-Pro filter mount for added creative options. The mount has a front accessory thread and is made of brass.
The F-Pro mount has become thinner than earlier standard mount. Now it can be used with wide angle lenses without vignetting.
Another advantage of the F-Pro mount is its modified retaining ring, which is no longer threaded in from the front, but holds the filter glass in place from the back.
When removing a filter that is screwed on too tight, the retaining ring is not loosening.
