Instruction manual

The viewfinder extension is intended for use when
shooting from a bird's or worm's eye view, or when shooting
from the hip or over obstacles. The extension tube (a) is
fitted between the camera and the viewfinder eyepiece.
Neither the universal panning/pivoting feature of the
viewfinder unit nor the image compensation is affected. As
with the viewfinder eyepiece, be careful not to cross-thread
the large mounting ring when installing the extension and be
sure to seat the locating nipples before tightening.
CARE! The mounting ring has a double thread. If it doesn't
tighten easily at once, unscrew and start again. Do not use
force. The same care must also be taken when fitting the
viewfinder eyepiece.
