Lenses; Parts And Components; Shutter Speed And Aperture; Exposure - Hasselblad 501CM User Manual

Lenses

500 series cameras are compatible with
lenses that have an integral leaf shutter,
namely, all C series lenses. F series lenses are
compatible only with cameras from the 200
series.
CFi / CFE lenses are the latest developments
and are mentioned and illustrated here as
the conventional choice.
C, CF and CB lenses, although differing in
specification and appearance to CFi / CFE
lenses, are operated in a very similar man-
ner but please see the relevant instruction
manuals for complete details.
Parts & components

Shutter speed and aperture

The shutter speed selector ring is the ring lo-
cated closest to the front of the lens. To set the
speed, turn the ring until the desired marked
shutter speed position aligns with the central
lens index.
The white scale shows the shutter speeds, and
the orange scale the exposure values (EV).
The orange 'F' setting is used only when the
lens is attached to a Hasselblad camera in the
200 or 2000 series with a focal plane shutter.
The operation of the diaphragm is not affected.
The 'F' setting can only be engaged/disengaged
32
when the orange lever is pressed.
If the F setting is used, exposure errors will
!
occur since the shutter remains open.
The aperture setting ring is the second closest
ring to the front of the lens. The aperture value
is also set against the central lens index. The
diaphragm is automatic and stops down to the
preset working aperture at the start of the ex-
posure sequence.

Exposure

As a general rule for all shutter speed settings
except B, you should keep the release button
depressed until the lens shutter has opened and
