This 72mm Tiffen 85B ND Filter 72mm 1-Stopblends both an amber color conversion 85B and a 0.3 neutral density filter. The ND filtration provides a 1-stop exposure reduction for darkening the entire image in order to photograph with a wider aperture or slower shutter speed than normally required. The 85B filtration covers the entire filter plane and converts the color temperature to 3200K for use with type B (tungsten) film.

This filter is made using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass, grinding flat to a tolerance of 1/10,000th of an inch, and then mounting to precision metal rings.

0.3 Optical Density    ColorCore Technology    Amber 85B and Neutral Density    Warming Filter to Decrease Color Temp    ND Filter to Increase Exposure Length

Combination of both an amber color conversion 85B and a neutral density filter.

0.3 ND filter darkens the image, allowing you to photograph with a longer shutter speed or wider aperture than normally required.

85B filter converts the color temperature to 3200K, allowing you to use type B tungsten-balanced film in daylight situations.

Q: 8. What size lens cap do I need?. I have been told that a 82MM lens cap is the right size as the front portion of the filter is made bigger to insure the filter does not vignette.

A: The front thread on that filter is 86mm an 82mm is too small.The only type of cap that will work is a push on lens cap and in most cases it will be a bit looser than a regular snap on cap.This one should be about the best fit, a href= http://bhpho.to/1wBcCRN target= _blank http://bhpho.to/1wBcCRN./a

Q: 10. 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.
