mechanism automatically closes the
diaphragm at the time of shooting and makes
the Bellows FL almost as easy to use as a fully
autorrtatic lerts. Focusing is performed with a
bright field of view. The bellows has a built-in
strut to prevent blur. The Slide Duplicator FL
for duplicaiing slides can be attached to the
end of the Bellows
The use of a macro lens especially cor­
rected for close-up photography is particularly
recommended for photography with the
bellows.
