By maddoc2003jpHello Forum members,
I am hoping to get some information about the Leitz BELUN 1:1 copy stand for the Leitz Elmar 5 cm lens in combination with a macro-tube. The BELUN set that I just received contains the three rods imprinted "ELMAR" and a macro (extension) tube imprinted "ELMAR SUMMAR 1:1". I have seen photos of similar setups a couple of times online so I thought it should work for 1:1 reproduction (I want to digitize film using a SONY A7"). Testing the setup yesterday with my SONY A7 + KF Concept E - M-mount adapter + M-mount - LTM adapter + BELUN macro tube + Elmar 5cm lens + 3-leg copy stand setup, I wasn't able to achieve any in-focus image with the Elmar lens in any focussing position and aperture f/9. I only get grain resolution (or sufficient sharp images) if I push the Elmar halfway in. My question is now if there are any variations in the setup or settings required?
Any tips or info is very welcome.
I'm tackling the following issue since ages . I would like to use my 82 Apo Televid as a lens , for various purpose : nature , and possibly astrophotography.
A) i'm chasing the leica 42306 adapter (no longer in production, but available in some places)
I have a question with this adapter , it's offers a T-mount interface in the back (camera side) but i've seen a female thread. I'm puzzled because I would have been expecting a Male thread, because all the T-mount camera adapter I have seen have F thread in the front.
Anybody having experience of such adapter would be welcome.
B) even more difficult question: my ultimate idea is to use the Televid as a "deluxe" guiding scope in astrophotography: for that purpose, I would like to use its native focal length of 440mm, that is to say bypass the 42306 that works as a focal multiplier .
I have seen that when one removes the eyepiece of the Televid, there is a Male thread (in parallel with the Leica "bayonet" mount (translation from French). This thread looks like 42x1mm or 42x075mm . I just wander if it would be possible to adapt an eyepiece holderr to this thread, to use standard eyepieces or a camera.
Any help, comment, advice, would be highly appreciated
