This is a bit of a learner question. I just got a Tokina 11-16mm lens with a canon mount to go with my canon mounted scarlet. I would like to get a second Tokina 11-16mm with a PL mount to go with my RPPs and PL mounted scarlet but cannot find any. Question is how do I get a Tokina 11-16mm to mount on my PL mount scarlet ? What options are available to me ? Thanks in advance.
