The 77mm #21 Orange Filter from Tiffen is a filter designed to build contrast in black and white photography and creates separation between the tones. The filter absorbs blue and blue-green colors, rendering blues darker such as for skies in landscape or aerial photos and water in marine shots. The filter has a filter factor of 4.5, so you must increase your exposure by 2 1/3 of a stop to compensate.

Tiffen filters are not dyed, but are manufactured by using ColorCore technology. This process laminates the filter material between two pieces of optical glass and grinds down and polishes the glass. The glass is then mounted to the metal ring, which after that can be screwed onto the lens for the desired effect.

Q: 3. What is the filter factor of this?

Q: 4. Can I mount this on top of a circular polarizing filter? Is there a downside to doing that?

A: The Tiffen VND filter consists of two circular polarizing filters...two CP filters together create the VND effect. Mounting this on top of a circular polarizing filter may cause some undersired effects such as cross polarization, vignetting in addition to difficulty adjusting the two filters as both turn and are adjusted by hand... if you mount the CP, then the VND it would be difficult to control both as they are turning. We recommend using a straight ND and then a CP instead.

Q: 5. Does this filter have a front thread?

A: Yes, the filter has a 52mm front thread.

Q: 6. Are these a good solution for using with Rokinon cine lens (which don’t have a filter thread to screw anything into)? Trying to work out how I use fixed ND and polarizer filters with the Rokinons without a matte box (when using on a gimbal).

A: It entirely depends on the Rokinon lens you are speaking of. Virtually all the Rokinon cine lenses take filters (on exception would be the 14mm) whereas the Rokinon Xeens cannot and you would most likely use this: NiSi 114mm Shatter-Proof Protector Filter B&H # NIR114EXP Generally on a gimbal, a matte box is not used and only one maybe two screw on filters would be considered for obvious size and weight issues. In order that we may further assist you, please write telling us in more detail of what you wish to do. sales@bhphoto.com.
