See the above pictures for an idea of how to attach the assembly to a standard Canon or
Fujinon lens, but please read the rest of the instructions before continuing.

-IF you have one of the smaller Fujinon lenses (Th16x5.5, S14x7.3, S16x7.3, S12x5,
A12x6.8), you will have to make one small change (see pictures below). The aluminum
bracket that screws onto the lens barrel (A) comes oriented to fit standard Canon and
Fujinon lenses, but to make it fit the smaller Fujinon lens you will have to remove it and
flip it around (note that one side of the bracket has a slightly smaller arc – this will be the
side facing the barrel of the smaller lens).

Loosen the black tee-head screw that fixes the bracket to the stainless steel rod and
slide the bracket off the rod (see picture 1 on previous page). Unscrew the black
knurled-head screw from the bracket until it comes out completely (A). Now insert the
screw from the other side, threading it in until it is captured (B). Mount the bracket on
the rod (with the smaller arc and screw tip facing the lens) and you will be ready to
attach the assembly to your lens.
