B+W 65-072247 overview

  • 1Description

Dedicated to infrared photography, the 40.5mm 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.

    B+W 65-072247 reviews

    40.5mm IR Dark Red 092 Filter is rated 3.5 out of 5 by 2.
    Rated 4 out of 5 by from not as dark as my r72 Nice filter, its not as dark as my R72 (but very close), so it allows slightly more light to pass through (this is not necessarily a bad thing as it helps add more artificial color which can be very artistic). The R72 is the Hoya comparable filter, so if you use the R72 note that this one allows slightly more visible red through. It fits the lense of my IR modded Olympus C-5060 without the bayonet adapter (saves space when traveling).

    Rated 3 out of 5 by from good and bad things The quality of the product is great. but the in-stuck information is not always up-to-date. Because of this reason I got one of my orders after 2 months. But mostly on-time.
