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

I think someone should kickstart this.  I think combining a helicoid with a focus tunable lens would really be quite useful.  You wouldn't have to trade off between depth of field and working distance.  Though, it would probably only be feasible in the 35-80mm range due to conventional constraints like aperture and sensor size.
