    How to Filter Large Diameter Lenses

    I would like others input on how they use filters for extremely large lense. I am particularly interested in 105mm and 122mm. It would be easy if the other side could use a smaller filter but in this case Schneider Fine Art lenses this option is not available. Thanks for your help

    I use an Army surplus filter used for aircraft type cameras. There is a supplier on the east cost that may still have them. I have a red, orange, and yellow. Heavy enough glass that they have been dropped on rocks and only a small chip on the edge. (I don't plan on doing that as a habit).

    Technology is not a panacea. It alone will not move your art forward. Only through developing your own aesthetic - free from the tools that create it - can you find new dimension to your work.

    Gel or polyester filters. I usually use 4" Lee polyester filters or Wratten gels for lenses up to 105mm. You can get 6" gel filters for even bigger lenses.

    You can also mount a gel holder inside on the rear element, even if there are no threads. There are some gel holders that use a spring or clamp mechanism. For some lenses that are impractical to filter in front, I've epoxied a square filter holder to the back of the lensboard.

    Cokin X-Pro covers up to 110, possibly 120 - the filter size is 130x160 (iirc) and majority of Cokin filters are included. Tiffen makes a lot of 138mm filters and 6x6 filters, I'm sure somebody must make a holder ...

    I think a set of square (or rectangular) filters, even quality glass ones, is cheaper and easier to work with than an assortment of step rings and large circular filters.
