B+W 65-072240 overview

  • 1Description

Dedicated to infrared photography, the 39mm IR Dark Red 092 Filter from B+W is a specialized filter for both digital and film photography. It has a nearly opaque, dark purple appearance when held to light, and is designed to block all visible spectrum light up to 650nm. To produce surreal effects, the 092 filter allows only 50% of light pass just below 700nm, and from 720-2000nm more than 90% of IR radiation passes. Since most infrared films are sensitive up to 1000nm, this transmitted red portion of the spectrum still affects the exposure. Due to the nature of infrared photography, the filter factor for this filter is highly variable and depends largely on your film sensitivity and lighting conditions.

This specialized filter is uncoated and uses high-quality Schott glass for its construction to maintain imaging integrity and optical clarity. It also features an F-Pro brass filter ring for durability as well as jamming prevention.

Used for infrared photography applications with digital cameras and specialized IR films.
Blocks all visible light up to 650nm while allowing greater than 90% radiation transmission between 730-2000nm.
Variable filter factor depending on your film sensitivity and lighting conditions.
Constructed from Schott glass for optical clarity.
F-Pro brass filter ring helps to prevent jamming and provides additional strength.
Plastic case included for storage and transport.

    39mm IR Dark Red 092 Filter is rated 5.0 out of 5 by 6.
    Rated 5 out of 5 by from A must for Ilford SFX200 I bought this particularly for use with Ilford SFX200 in my Voightlaender R2 with Color Skopar 35mm II lens. The TTL metering functions fairly accurately even with the filter in place. I do feel about a +1 exposure compensation is necessary with the R2 to get the optimal infrared-like results with this combination of camera, lens, filter and film. Without the +1 compensation the exposure is correct it just doesn't yield the infrared effect as nicely.I also tried this with my Fuji 60mm on an XPro-1 and I could achieve the infrared-like effect though I wasn't as satisfied with it as I am with the SFX200.

    Rated 5 out of 5 by from The Best Available This filter has produced great results on my M6 with Rollei IR400 film (exposed at ISO 25). I can hold the camera and shoot at f/4 without a problem. I hear it work just as well on the M8 and M9. I had the 093 which is too opaque to hand hold, but regardless when you buy a b+w filter you're getting the very best.

    Rated 5 out of 5 by from Great filter if you are an IR lover I use this filter on my Leica Summicron 35mm F2.0 with M8 which can easily take IR picture without any alteration on the camera and even no need for Tripod.Here is the sample:@
