    Re: Need Holes Drilled for Lens Flange

    Good idea but as a piece of additional info: I have not and haven't (yet) had any reflections.... or any other detrimental imaging effects.

    Maybe no reflections, but perhaps there might be some loss of contrast?

    If you shoot into a VERY bright white overall area, you can sometimes see a round flare on film from internal reflections, reflecting from film to ring...

I also had a generous offer from a forum member to drill them for me as well.

    Thanks, all!

    You are set, if it slips put a piece of good tape on the ring and board. If it works leave it. Then you still have a virgin board.
    Looks good, Mike

    Very good work. People that shoot digital won't get pictures like that. Looks like you are set

    I have mounted ass many rings with bolt & nut as with bot and threaded hole.It is fast and secure. If concerned, add Loctite to the bolt threads before putting on the nut.
