The 72mm #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: 1. Will this fit a Nikon 80-400 VR AF lens?

A: yes, check lens specs, Filter Thread, Front: 77 mm

Q: 2. will this fit lens Sony 28-75mm f/2.8?

A: This filter will fit on any lens designed with 67mm filter threads, please check the specifications for your particular lens to determine the filter thread size.

Q: 3. Does this filter suit Canon 514 XL super 8 camera?

A: We recommend that you contact Canon for the filter thread specifications for this camera. This information may also be available labeled near the lens or in your manual.

Q: 4. Can/Should this be used in conjunction with a UV filter?

A: We recommend always having a Tiffen UV filter on your lens. The Tiffen VND can attach to the outside filter threads on the UV filter, however when shooting at wide angle you may experience vignetting. If so, you will have to remove the UV filter and just shoot with the VND.

Q: 5. Can these filters be stacked on b+W uv filters. Planning on using them for 58,72, and 77mm lenses I have with the uvs On.

A: I only stack this with an adapter to accommodate the smaller lenses. When I was looking at this filter, I chose the one for my largest lens and then bought adapters to use it on the smaller lens. This is the last filter I use in a stack and have used it stacked on my uv filter in 77mm.

Q: 6. Would this filter fit a Sigma 24-70 lens for canon?

A: This filter will fit any lens with a 77mm filter thread. Please check your lens to confirm the filter thread size before purchasing.

Q: 7. Can I use this filter along with a polarizer filter?

A: Yes, this filter will work with a polarizing filter. The Enhancing filter is designed for use when shooting scenes with warm tones and works best for that type of image.

Q: 8. can you get a filter cap to go on it?? thank you, linda

A: Forget using a conventional lens cover. Look into a LensCoat Hoodie.

Q: 9. Can this Tiffen 77mm Variable ND filter be stacked onto another nd filter to allow more stops while still using the variable? If so can someone add a link to a filter that would work underneath this one? I am trying to do slow exposure in bright sunlight and I cannot reach the desired results with this filter alone.

A: Not sure why you need another ND. This variable ND allows you to completely block all light even from full sunshine. I have this filter. Plus you never should stack these types of threaded filters as they can become permanently stuck. The threads are very thin.

Q: 10. Does this ND filter also act as a polarizer filter? Do I need another Circular Polarizer filter to cut out more haze or would that be overkill? Thanks for any inputs!

A: No, the NF filter will not take care of haze, but really, neither will a CP do that good a job on haze. I use the variable ND filter to control exposure time during the day for something like a capture of a waterfall or stream. To knock back glare from the water, or say shiny leaves under a forest canap, a CP needs to be added. As for haze(?)- that's best handled in post with the dehaze slider, IMO.
