  • Mounting a 15mm rail block to the top 1/4-20(s)

    Hey all,

    I've recently realized that BMD used (as far as I can tell) a nonstandard spacing for the threads on the top of the camera. This means that none of my cheeseplates/offset rod clamps/misc parts will allow me to attach my top handle via it's dual 15mm rods. So I was looking at plates to adapt the holes to fit one of my rail blocks, but I'm not having any luck. The closest I've found is the redrock micro top plate, but that doesn't have enough 1/4-20 holes. Is there anything close that will allow me to easily and hopefully inexpesiveally attach a 15mm rail block (something along the lines of this) to the top of my camera?

    I can't be the only one having this problem, Peter went as far as having a custom plate machined (BMD Forum).

    Berkey sells a BMCC Top Cheeseplate, which, together with one of their rod clamps, properly positions rods 85mm from rod-center-axis to lens-center-axis.

    I wanted an even smaller & lighter top plate, so I had one made for me.

      So I place an order for the Berkey Cheesplate and rod clamp, but now I'm wondering if the far less expensive redrock version might work. The ultraplate in combination with their microclamp. Thanks for your help Peter, and I dig your blog.

      EDIT: Just spoke with Redrock support and that combo won't fly. They recommend a cold-shoe adapter which is unnecessary imo. I'm sticking with my Berkey purchase it looks like.

        Peter, you need to stop wasting your time with all these aspirations of becoming a cinematographer. Clearly your talents and future wealth lie elsewhere, in design and manufacturing. Take a look at how OConnor got his start and take the hint:
