B+W 66-1014112 Overview

  • 1Description

The B+W 39mm UV/IR Cut MRC 486M Filter is an ultraviolet and infrared control filter that is useful for digital cinematography as well as still photography. While recording video with a CCD or CMOS camera, multi-stop neutral-density filters are used to maintain proper exposure by compensating for increased light levels when widening the camera lens's iris to obtain a narrower depth of field. As the increased amount of light passes through multi-stop neutral-density filtration, visible light is progressively blocked, while infrared light is allowed to pass through. As the proportion of infrared light that reaches the sensor of a camera being used for digital cinematography becomes greater, the results can show unwanted color shifts, particularly in dark areas of the frame such as shadows where the appearance of black is dominant.

When the B+W 39mm UV/IR Cut MRC 486M Filter is applied, 88% of ultraviolet light waves are blocked at 380 nanometers along with 95% of infrared light waves at 700 nanometers, helping to ensure that light falling on a digital camera sensor is limited to the visible spectrum. When used along with multi-stop neutral-density filters while recording with a digital sensor, potential infrared color shifts are prevented or minimized, preserving color accuracy throughout the frame. This filter may also be used to help ensure that the appearance of unwanted blue casts is reduced while recording digital video or still photos under daylight that also features intense ultraviolet light.

The front surface of a B+W 39mm UV/IR Cut MRC 486M Filter includes thirty layers of interference coatings which allow it to limit the light that falls on a digital camera sensor to the visible spectrum. When combined with a wide-angle lens, lower-frequency wavelengths of visible light associated with yellow, orange, and red colors passing through the filter and along that lens type's curved edges can be impeded in a significantly greater degree than higher-frequency wavelengths of visible light associated with blue and violet colors. This can result in an unwanted cool cast along the edges of an image taken with a B+W 39mm UV/IR Cut MRC 486M Filter and a wide-angle lens. To avoid such color shifts along the edges of an image when using this filter, it is recommended not to be used with lenses that are intended to provide an angle of view greater than 60°.

Eight layers of anti-reflection coating are included on the rear glass surface of this B+W 39mm UV/IR Cut MRC 486M Filter. This Multi-Resistant Coating (MRC) prevents internal ghosting and reflections, offers protection to the filter substrate, and helps its rear surface to stay clean for longer than with uncoated filters.

B+W filters are constructed from Schott glass for increased optical clarity and color fidelity. The B+W 39mm UV/IR Cut MRC 486M Filter features an F-Pro brass filter ring for durability and jamming prevention, as well as 39mm front filter threads that allow it to be paired with other filter types. When in use, but not combined with another filter that provides a specific effect, it is recommended to place a clear, protective filter over the B+W 39mm UV/IR Cut MRC 486M Filter to prevent damage to its front interference coatings.

88% of ultraviolet light waves are blocked at 380 nanometers, before which they are further removed, reducing bluish cast of daylight when recording video or still photos.
95% of infrared light waves are blocked at 700 nanometers, after which they are progressively eliminated.
Useful with CCD or CMOS sensors to filter out infrared light pollution that cause color shifts frequently associated with high-definition recording with multi-stop neutral-density filters.
Does not require adjustments to exposure while in use.
Thirty layers of interference coatings on front surface limits light that falls on a digital camera sensor to the visible spectrum.
Multicoated rear surface prevents internal ghosting and reflections.
Constructed from Schott glass for optical clarity.
F-Pro brass filter ring helps to prevent jamming and provides additional strength.
39mm front filter threads allow use with other filters to protect front surface or combine with other effects.
Plastic case for storage and transport.

    39mm UV/IR Cut MRC 486M Filter is rated 4.8 out of 5 by 13.
    Rated 4 out of 5 by from cost-effective cut cost-effective cut of uv and ir, appears to have no density effect on light passage, metal retainer ring soft but workable

    Rated 5 out of 5 by from Perfect for Leica M8 I have never used a filter before on any camera but after color correction issues during an event shoot caused by the missing IR filter on Leica M8 I thought I would try the B+W 39mm UV/IR Cut. It is early days yet and I need to shoot a lot more in different lighting condition to form a firm opinion but for the moment I'm extremely happy with the product and the service provided by B&H. All my M lenses are 39mm therefore one filter will suffice.

    Rated 5 out of 5 by from Must have on every lens for Leica M8 The B+W UV/IR Cut filters are a must on every lens you own if you are using a Leica M8 (for accurate color balance), which does not have a IR filter on the sensor. I also have some Leica UV/IR Cut filters which are more $$$ but I must say the B+W filters are completely equal in quality! The B+W filters come in silver and black too so you can match your lenses with the correct color.

    Rated 5 out of 5 by from Professional-Grade construction I use this on my very best Leica lenses; specifically the 50mm Summicron. There is no question that the light transmission through this filter is the best that is possible, with minimal loss in image quality. Great photographers like myself deserve only the very best, and B+W is worthy of the elite few.

    Rated 5 out of 5 by from Best uv/ir cut filter after Leica's This filter does the same thing than the one made my Leica does, but it is less costly. I only use it on my Leica M8 to control colors. Great filters, very expensive, but still less costly than Leica's.

    Rated 5 out of 5 by from Great quality, does the job for Leica M8 B+W filters are superb: top notch glass in a a solid brass ring. This specific filter is a must have for use with the Leica M8, otherwise black fabrics tend to appear more of a magenta color.

    Rated 5 out of 5 by from Better and Cheaper than Leica's UV/IR I bought this to use with lenses on my Leica M8. It is very well made, works perfectly eliminating IR colour casts and is less expensive than Leica's own filters. Great filter.

    Rated 5 out of 5 by from Great alternative to Leica IR UV block This excellent B&W UV IR blocking filter is absolutely effective and the build quality is top notch. It is an affordable alternative to the very expensive Leica filter.
