    Default Camera lens filters for projector aperture...?

    I KNEW I would forget to ask at least SOMETHING on the list while at SELEM !

    Anyway, for those of you using camera lens filters for the beam aperture on your projectors, could you recommend a specific low-loss filter that seems to work well for your projector?

    Thanks!

    Pretty much any multicoated UV filter is good. I can recommend Hoya ones as their coatings seem particularly good.

    That depends on how far away your scanners are mounted from the aperture, but I would say 55 or 60mm would probably be sufficient. I use 55mm.

    I second that
    These are very impressive in how much they don't reflect I have a 77mm one on my projector and it's brilliant however a tad expensive ($133.00 Australian)

    You won't go wrong with one of them

    Also make sure it's the Super Multi-Coated (I had difficulties finding one and I had camera sales people try and sell me the generic Hoya filter)
