11.2 Lens Support
Heavy lenses may require additional lens support. This guarantees that
the flange focal depth is not influenced by the lens weight and reduces
stress on the lens mount.
To support a lens, use 15mm or 19mm rods and a fitting lens bridge.
15mm rods can be directly inserted into the camera housing. 19mm
rods require a bridge-plate with 19mm rod support (BP-12 or BP-5/BP-8
+ BPA-1).
The lens bridge LS-10 for 15 mm rods is mounted to the rods by
pushing it on the rods from the front, while the lens bridge LS-9 for 19
mm rods is mounted to the rods by pushing it on the rods from the top.
