BOLEX H16 SBM Instruction Manual page 47

Extension tubes. Used in macrocinematography to
achieve magnification of minute subjects, such as
insects, filmed at very short range. The reflex viewing
system of the H 16 SB and SBM cameras permits highly
accurate framing and distance setting. The tubes are
supplied with a calculator table.
RX-Fader. Automatically and smoothly opens and
closes the variable shutter, thus permitting professional
quality fades and lap dissolves.
Electric motor. See page 18.
Cable releases. Recommended for normal or single
frame filming when absolute steadiness is required.
Two lengths available: 21" and 40".
Bolex lightmeter. It is always advisable to use an
exposure meter, particularly when filming in colour.
The Bolex lightmeter is designed for motion filming
and especially calibrated for use with your camera.
