I know similar info has been posted about this, but for various reasons, Im posting it again. Sorry if this upsets anyone
I am putting together another Super point & shoot system. This one happens to have the 'standard' Optar 135mm lens, and as we all know, it needs a 38mm push-on filter adapter...
Well, I've been looking for one for a couple of years now with no luck (I hate auctions!)
So, along comes tonight, when I lose out on an auction for an 8x10 FP shutter which I've also been looking for years now (did I mention I hate auctions!). Being totally depressed, I decided to do something productive to make me feel better...
I look through my box of goodies for some kind of filter adapter. Some too big, some too small... Can't do anything with the small ones, but how about the big ones?
I find a nice Series VI to Series VII adapter. It's only about 5 or 6 mm too large... Now, I have strips of mat board cut here to make lens caps. I take a strip of that and wind it inside the adapter on the rear where the threads are. Comes to about 39mm. Not bad! So I cut the strip length-wise so it's the same thickness as the ring of the adapter.
I could glue the thing together, but I need that 1mm... I also have black 'gaffers' tape here in 3/4 width. I decide to cut a length that just wraps around the outside of the rear threads on the adapter, wrapped as tight as I can get it so it digs into the threads. Then I fold over the entire length inside the adapter and press it all the way around. It completely covers the threads on the outside, the mat board strip on the inside and has about 5mm left over to catch the inside of the adapter ring holding it all together. measure it up, just a tad under 38mm and a perfect fit on the lens! And since I used tape, I can always take it apart later...
This same idea would work with any ordinary filter (UV or Daylight type would be good), but I didn't have one laying around...
Since the push-on adapters are getting hard to find, modifying other adapters or filters this way can be a cheap & easy way to get a filter, hood, or place to hang a Lee rubber band filter system on front of a lens...
Now if we just knew the internal sizes of standard filters, we could easily make these things without a junk box
Just thought I'd share, and get some aggravation (and depression) off my chest...
Off to bed...
