B&W 58mm UV Black (403) Filter - This filter should not be confused with a traditional "UV" filter. This specialized filter is opaque to the eye and passes UV A radiation from 320-385nm. It also blocks all visible light. When used with the appropriately sensitized film, it is especially effective when used in forensics or in certain flourescent photography.
The filter ring is made from brass yielding a stronger product. Brass filter rings are also less prone to jamming. In addition, the seal between the glass and filter ring is exceptionally strong giving the filter added strength and durability. The excellent Schott Glass used in the manufacturing of this filter is legendary and synonymous with the highest standards of filter production. It comes with a solid 10-year warranty.

Using the filter with an IR modified K7 (clear conversion with hot filter removed). The filter is very dark, but using live view allows for composition. Handheld shots are possible in good lighting conditions, though it did take a moment to find the proper combination for good exposure due to the file factor.
