Product Description

Used for photography with infrared films. lnfrared film is also sensitive to ultraviolet rays and the shorter wavelengths of the visible spectrum so it is necessary to filter out all but the infrared rays. R72 passes only infrared rays above 720nm RM90 passes only that above 900nm. Often used in crime detection, medical photography, detection of distribution of vegetation, etc. In ordinary photography with infrared film or infrared color film, the Y(K2), O(G), R(25A) and other filters can also be used to change the contrast or color effect.

This review is from: Hoya 77mm R-72 Infrared Filter (Electronics)

this filter is exactly the same as the RM-72 filter which is only about $45. As explained on various sites "the RM72 and R72 is the same filter from Hoya. Named differently for different parts of the world". So don't pay the ridiculous price these people are asking
