Need Holes Drilled for Lens Flange

[BrianShaw]

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...

BrianShaw's simple idea seems to work like a charm. I took the flange off the original board and screwed it into the back of the new board. Haven't tested for light leaks yet but I don't expect any. I still might go to ACE and look into having the screws properly tapped etc. But this may just work. 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

Thanks, everyone! Finally got to use this lens on a camping trip this weekend.

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

Do you think making an unthreaded hole backed up with a nut might work? Perhaps with some thread locker on it to keep it secure?
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.
