Bob, this is just a hobby for me too. The part about using reversed mounted lens (I believe) is in the 4th edition of the BTZS book. Phil talks about another used that did this. I guess the lens element he describes in the plans is no longer available. I loaned out my copy so I can't give you the page number, but it is in the edition I bought new about 1 year ago.Quote:

The 35mm lens has a 49mm thread and the meter has a 40.5mm thread, so I bought a 49mm to 40.5mm adapter then a 49mm to 49mm coupler I think it is called a reversing coupler.
I hope this helps please email me if you have any questions.
I would love to own a real one but the Ebay scene is too dangerous for me. :)
