Does anyone know where I can source a variable focus lens to play with. The ml-20-35, by optotune seems really interesting. Edmund optics carries the electrical versions. M12(s-mount) to c-mount to nex are readily available, but I can't seem to find anyone carrying the manual lens.

I think it would be interesting to play with because it seems to approximate human vision. I'm really curious what happens when the focal length of a lens is changed without changing the distance.

Sounds like a revolutionary new technolgy. If optical quality and durability of these lenses is good it could become a key fo a new generation of lenses.

Thank you for sharing!

Best regards
