10.2 Lens Support
Heavy lenses may require additional lens support. Using a lens support
guarantees that the weight of the lens will not influence the flange focal
depth and reduces stress on the lens mount.
To support a lens use 15mm studio or 19mm studio rods and an
appropriate lens bridge. 15mm studio rods require a bridge-plate with
15mm studio rod support, such as a BP-3/BP-9 + BPA-1, while 19mm
studio rods require a bridge-plate with 19mm studio rod support, such
as a BP-12 or BP-5/BP-8 + BPA-1.
Mount the lens bridge LS-10 for 15 mm studio rods by pushing it onto
the rods from the front. Mount the lens bridge LS-9 for 19 mm studio
rods by clipping it on the rods from the top.
