15mm rods mount for HM700
 

The only rods mount currently shipping for the HM700 seems to be Zacuto's Zephyr 700.
Zephyr700 - Zacuto
This is what we had on one of the cinema rigs in the NAB09 JVC booth. The other had a solution from Arri that is compatible with a V-plate.

Apparently Cavision is working on a revised rod system as well, but I haven't heard about Chrosziel yet.

ADDENDUM: It appears Vocas has a HM700 compatible 15mm rods solution now as well.
