About B + W 40.5 Infra-Red Filter

B & W offers three filters for infrared photography, each with its' own unique features.

• This dark red filter is primarily for black and white infrared films.
•It filters out light below 650 nm.
• With color infrared film it produces pictures of a pure red image while making good use of the relatively low sensitivity of infrared films.
• Filter factor is approx. 20 - 40.

• This black infrared filter will filter out the entire visible spectrum.
• It is used with black and white infrared films with a sensitivity up to 1000nm.
• Filter factor is determined by the film sensitivity.

• This orange colored filter blocks the blue and blue-green portion of the visible spectrum up to 500 nm.

Questions about this item:

Roo A  Will this fit a standard 35mm camera lens?
Andrew R  That really depends on the lens. Most lenses for 35mm SLRs have filter diameters that range between 49mm and 82mm. You'll need to check the diameter of the filter ring on your lens to confirm fit.
