Hi Mark,
1, Its a kinor 16 lens from a kinor camera. I own two of these lenses never had
a problem very tack sharp with nice multi-coating, one problem is that on S16
it only works from 50mm up..so you loose a lot on the wider end of the lens
3, No, it is a Kinor mount,
4, I have had my Kinor and Kinor lens converted to S16 and PL mount so I guess
a arri mount is possible?
5, Of course! :)...Cheers
Sean
