Ultra16 50mm on Arricam LT

[Uli Meyer]

Hello All,

 

I recently got into shooting on film and am on a steep learning curve. I just tried to mount an Arri Ultra16 PL mount 50mm onto my Arricam LT but the back of the lens touches the mirror. I realize that the Ultra16s were made for S16 and they fit nicely onto my 416 but I didn't think there'd be a problem fitting them onto the Arricam.

Do Super35 lenses generally have a shorter back end?

 

Thanks!

Yes you want to avoid putting 16mm format lenses on a 35mm film camera, they can protrude further back than 35mm format lenses and potentially hit the mirror.

 

The flange depth (distance from mount to film plane) of all PL mount cameras is the same, but 16mm reflex movie cameras have more mirror clearance space than 35mm ones.

Thank you Dom! I'll keep that in mind, that's very good to know.
