Q: 6. 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: 7. 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.

Q: 10. Will this filter fit my Canon serenar 50mm 1.8 ltm rangefinder lens ?

A: No, the Tiffen 40.5mm Skylight 1-A Filter would not fit the Canon Serenar 50mm f/1.8 LTM Lens. The Canon Serenar 50mm f/1.8 LTM Lens uses 40mm filters, so the Tiffen 40.5mm Skylight 1-A Filter would be too large to fit properly on the Canon Serenar 50mm f/1.8 LTM Lens. While we do not have a 40mm skylight filter, we do have a NiSi 40mm PRO UV Filter, B&H # NIRUV40, which may be used as a protection filter with your lens.
