The
standard lens
of
MIRANDA
Sensorex
gives sharp focus
up
to
45mm
(17") (roughly
21
X 14cm fills up the entire viewfinder field).
But to shoot
at
closer distances, the extension
tubes become necessary.
• Extension tubes are available in four lengths,
one AU Adapter and three intermediate
rings.
The
AU Adapter
is
equipped
with
a screw and bayonet
mount;
the rings use
the inside screw mount.
•
The
AU Adapter has the same length
as
Tube
No.
1.
•
The
tubes are
of
lengths
8mm,
16mm
and
32mm, and can be used separately or in
combination to give close-ups
of
o.15~~
1.23
time magnification.
• Magnification ratios and exposure factors
are shown on the next page (for
50mm
lens
at
infinity).
• These are handy to use in copying photo-
graphs or taking pictures
of
insect specimens.
