The 95C with coarse thread Tiffen #12 Yellow Filter 95C Coarse Threadfrom Tiffen #12 Yellow Filter 95C Coarse Threadis a filter designed to increase contrast and tonal separation for black and white photography. The filter absorbs blue colors, rendering blues darker. Haze is minimized for aerial photography and excessive blue is removed for astrophotography. The #12 Yellow Filter is recommended as a basic filter for use with Kodak's Aero Ektachrome Infrared Film. The filter has a filter factor of 2, so you must increase by 1 full stop to your exposure 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. What do they mean by coarse thread , and how is this different from the other Tiffen 3-stop ND filter at the same price?

A: Lenses with 86mm filter threads use a coarse thread which is 1.0 pitch. This is different than smaller filter thread sizes (82mm and lower), which use a .75 pitch. Based on the information you provided, we are not able to determine which filter you are referring to. Please provide a link or a Tiffen Mfg #.

Q: 2. Will this reduce or remove Purple Fringing from Night Shots? What about Chromatic Abberations?

A: This is a specialized UV filter for blocking UV into the violet region of the visible light spectrum. It helps to prevent unsharpness during ultraviolet fluorescence photography caused by chromatic aberrations due to intense UV lighting situations.

Q: 3. what is the definition of coarse thread ?

A: Coarse thread would refer to a lens filter with a pitch of 1, instead of the standard 0.75 pitch. Most filters between 39-82mm and 127mm use the 0.75 standard pitch. Filters sized 86-112mm and 122mm are typicially 1 pitch, or coarse thread. In any case, you simply need to purchase the filter that is designed for the filter thread size of your lens. The manufacturers concern themselves with making the correct pitch or thread size for the designated filter size.
