Most C mount to NEX adapters are too narrow for lenses like the C mount Tevidons to mount properly. I already found one adapter, an Optix C-NEX adapter that also has a m42 thread, but it was relatively expensive and I can't find it for sale anymore. I like having a spare adapter so I could use the Optix for another experiment. I ordered a few cheap C-NEX adapters that I thought might be wide enough. I've just received a C-mount to NEX adapter from Roxsen Click here to see on Ebay.de which took only 7 days to arrive in the Netherlands, and it does mount the Tevidons correctly.

Near mount diameter in mm:
39.0 No Name standard C mount adapter (some are even narrower)
40.8 Roxsen
41.0 Optix C/m42

To mount a c mount Tevidon you need at least 40.0mm.

I'll report about the other C-NEX adapters when they arrive.

That is quite surprising. A year or so ago no adapters wide enough were to be found and even some sellers that claimed to sell adapters to accommodate lenses with wide near mount diameters were not telling the truth.

42.5mm is wide enough to match almost all c mount lenses. Have you got any that don't fit?

I have a Fujinon 50mm f1.4 taken from CCTV camera and it fits the adapter.
