I have a different question about an M42 bellows.
I have an M42 bellows the female end of which takes an M42 lens, as it is intended to do and I want to attach another lens to the other end (the male end) which by rights is intended to screw into the camera body. Ideally I want an adaptor ring which is M42 female on both sides so as to convert the male end to a female end.
Another possible solution would be a ring which is M42
female on one side and has a male 49mm filter thread on the other. That could be used to attach the lens to the bellows by the filter thread. Does anyone know of such an accessory [I know rings are readily available that are M42
male on one side and have the male 49mm filter thread on the other]?
I would rather have a proper manufactured article but failing that I wonder if glueing two M42 extension rings together back to back i.e. male to male would be sturdy enough? Anyone had any experience of this?
I also have Leica thread enlarging lenses which could be used if I can get an M42 female on one side and Leica female on the other. That would perhaps be the best solution of all but I doubt that such a thing is made.
PS BTW
yeatzee your insect pictures are really impressive. Did you set up the pictures or stalk the subjects?
What lens did you take them with and what lighting did you use?
