Tiffen Variable Viewing 0.6 to 2.4 Filter (2 to 8 Stops)

The Tiffen Variable Viewing 0.6 to 2.4 Filter is designed to be held over a cinematographer or photographer's dominant eye and allows the primary effect of a neutral density filter to be conveniently previewed. By turning its rotatable front ring, this filter's 0.6 to 2.4 density reduces apparent exposure by 2 to 8 stops. Within that density range, different amounts of exposure reduction on a scene or image can be conveniently compared. The most desirable density can then be chosen, and using separately available lens filters, applied to a camera system with exposure settings that initially correspond to the amount of brightness perceived by the unaided eye.

Separately available, 49mm screw-on filters can be connected to the rotatable ring's front threads, providing the ability to preview a wider variety of filter effects in combination with an increase in density. For easy, repeatable control over density settings regardless if a 49mm screw-on filter is connected to it, the rotatable ring is also visually demarcated with dots that represent different density values.

This filter is constructed from Water White glass for increased optical clarity, and its aluminum-alloy filter ring assembly is durable while remaining lightweight. A 1" handle behind the rotatable ring enables comfortable, two-handed operation when adjusting density settings, while a detachable, 20" nylon lanyard allows the Tiffen Variable Viewing 0.6 to 2.4 Filter to be worn around one's neck, helping to ensure that it stays within reach during use.
