The Tiffen 4 x 4" Double Fog 1/8 Filter simulates the effects of natural fog or mist by creating a soft glow around highlights and lowering the overall contrast of the scene. When compared to the standard Fog filter, this filter places greater emphasis on lowering the contrast while maintaining sharpness and minimizing the effects of flare. The 1/8 density provides less fog effect that the 1/4 and requires no exposure compensation.

Tiffen filters are made using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass and grinding flat to a tolerance of 1/10,000th of an inch. This filter measures 4 x 4" / 101.6 x 101.6mm.

Q: 1. Could the double clamp be used to attach a gimbal (like the Ronin RS 2) to an extension pole? I'm weary of trusting the 1/4"x20 threaded screw to support the combined weight of the gimbal and my heavy camera.

A: It is possible to clamp a DJI Ronin S2 with an extension pole. Whether it would be sturdy enough would depend on the pole you're attaching with.

Q: 2. Does this work protect the lense from liquid splatter?

A: The Tiffen 62mm UV Protector Filter, B&H # TIUVP62, would protect the lens from direct liquid splatter. However, do note the filter is not waterproof. In the event of liquid splatter, it is recommended to wipe off the filter (and/or lens) as soon as possible. If you plan to be around splattering liquid, you may also consider purchasing a rain cover such as the Ruggard Fabric Rain Shield Small (14"), B&H # RURCFC714, or the Ruggard RC-P18 Rain Cover for DSLR with Lens up to 18" (Pack of 2), B&H # RURCP18, in addition to the UV Protection filter, or an underwater housing compatible for use with your camera.

A: The Impact Baby Double Header (B&H# IMME110) is made of steel, so it's especially strong. However, the manufacturer does not list a specific weight capacity.
