Bob,
Those cheap adapters basically always need shimming. I use 0.05mm copper tape. It sticks in place nicely, and can easily be stacked to the right hight and trimmed to fit.
Christian,
I remembered that I have mucho high strength shim material that is called "Havar." It is the same material that watch springs are made of and it has an incredable stength to weight ratio.
On my Cyclotron in my lab we use thin foils to isolate vacuum from targets, a jet of refrigerated Helium cools the foil so we don't burn a hole throuh it with a proton or deuteron beam while atomically transmutating materials to make them radioactive.
The following thicknesses are available: 0.0015; 0.00025; 0.0005; 0.000125; and 0.00095.
GEAR ALERT: I just bought a 50 R Lux known as an "E60" to use on my SL2-MOT. This is the last R 50 that only comes as a ROM version that will not mount on my SL2 unless I convert it to 3-Cam which is what I am currently doing. This is a rare lens, and only 2700 were ever made. Very highly rated and reguarded. Many people convert this lens with a Leitax adapter for use on Nikon, Canon, and Pentax DSLR's, so I kinda justified this purchase as not so crazy knowing that this lens could be easily used on my SL2-MOT, F3P, F3HP and perhaps a future DSLR like a DF or D4.
For a new lens mount and a set of cams I found three 3-Cam Macro Adapters at B&H to select from. Funny thing is that the least expensive one was acually the one in best condition. I paid $49.99 for the Macro Adapter. The Leitax sight had enough info via photos to show me that the holes are already tapped for mounting the 3-cams. "E60" is the filter thread BTW and that is how it is most easily distinguished.
