Related Questions and Answers

Q: 1. Would the 124mm -114mm be the best size for use on Rokinon Xeen lenses with an outer diameter of 114mm?

A: The SHAPE Flexible Adapter Ring for Clamp-On Matte Box (124 to 114mm) BH #SHCFR114 would be an excellent choice for your Rokinon Xeen lens with an outer diameter of 114mm.

Q: 2. Will this adapter work directly with 77mm Rokinon Cine lenses? The outside diameter at the front of my cine lenses appear to be approximately 80-83mm, where the lens hood would mount. Does this adapter clamp onto the outside of the lens thread where a lens hood would sit?

A: For my understanding, this particular Genustech Clamp On adapter 80 mm ring is a 'stand alone' clamp on adapter that will only work with a modified lens type or those Duclos Lens, in which I never had used one before. It will not work with any type of screw in adapters or screw on lens. I had ordered this adapter once before and hope that it would work on both my Canon lens and Samyang (Tokinon South east asia title?) with a screw on adapter lens for various size. But it doesn't work. So i had to order screw on adapter ring instead to be able to fit on my Genus Tech matt box.Hope this help.
