Zeiss lkon ropid-exposure meter. First the exposure meter must be set to the speed of the film in use. For this purpose turn the inner disc by meons of the smoll knob (8) until the relevont speed volue oppeors opposite the block stroke of the DIN or ASA window. The disc con olso be set to intermediote film speeds (fig.a). lf o film monufocturer hos quoted the film speed occording to o roting other thon the DIN or ASA systems,the corresponding index con be found in the conversion toble on poge 7. Since the speed of colour fi lm connot be meosured in the some woy os thot of block-ond-white film, the colour film monufoctur- ers ore unoble to give exoct speed numbers but recommend their films to be exposed "os o block-ond-white film of X DIN or XX ASA", Generolly this odvice is quite relioble, but in 5 fig. 4View original page 8

order to be obsolutely sure the Nettox owner should colibroie
his own equipmeni by moking vorious test exposures of differ-
ent stops ond thus deiermine the octuol speed of the film in
question ond the correct setting of your built-in exposure meter.
To meosure the prevoiling light the flop of the exposure meter
should be opened by gently pressing knob (3) to the left. (To
close it, press the flop slightly to the left with the right index
finger). Point the Nettox iowords the subiect so os to frome it
in the viewfinder. The white pointer (4) will then be seen to
deflect. By turning the setting ring (9), the smoll white circulor
mork should be moved until ii is exoctly olongside the pointer
os seen from obove (see fig. 4). The exposure time io be used
(outer scole) con now be reod off from the setting ring (9) for
ony operture of the lens (inner scole) ond vice verso.
The exposure times or shutter speeds to the left of 1/z denote
froctions of o second (e.g. 25 - L/zssecond, etc.); the figures
to the right of 1/z denote full seconds. ln order to ovoid confu-
sion the long exposure iimes ore morked in green.
The volues found should then be set on the operture scole ond
shutter speed ring of the Nettox.

Diaphragm
The correct operture of the diophrogm or "stop", for short,
depends on the depth of field desired (see poge 9). The red

The flosh leod from the lomp should be connected to the flosh contoct (11) ond only then the floshbulb inserted (fig. l0). When the releose knob (2)is depressed the floshbulb will be fired in synchronizotionwith the shutter. The copocitor-floshgunsFolding lkoblitz ond lkoblitz 0 con be slipped into the occessory shoe of the Nettox (5).Both flosh- guns provide on extremely bright flosh.
