Viewfinder Eyepiece Selection - Hasselblad XPAN II User Manual

 If you open the camera back by mistake before you
have finished the film, you will only have lost the last
exposed frame and the unexposed frames. The exposed
frames have already been wound back into the cassette
as the XPan II starts by withdrawing all of the film first
and progressively rewinding it frame by frame.
 Make a habit of turning off the camera when not in use.
The power save function will put the camera in stand-
by mode automatically after three minutes of inactivity
but it may reactivate if something presses against it; in
a camera bag for example.
 Check battery status regularly and always keep some
spare batteries in your camera bag.
 At very low temperatures, the batteries may not provide
sufficient power for the camera. Keep some spare bat-
teries in your pocket, for example, to keep them warm.
These can then be exchanged and be used alternately
while the cold batteries are being warmed.
 The dependable working range for the camera is -10° C
– +40° C.C.
 The LCD's may look dark at temperatures around 60° C
and react slowly at very low temperatures. This is quite
normal and does not signify a fault.
 When using a combination of the 45mm lens, pano-
rama format and transparency film, the natural light
30
decrease appears as slight light fall-off for critical ap-
plications. This is quite natural and is not due to lens
vignetting for a stopped-down lens. To minimize this
effect use an aperture of f/8 or smaller and avoid un-
derexposure. The effect can be completely eliminated
by using the Centre filter XPan for 45mm (3054453).
 Remember that it is roughly the central 20 x30 mm area
that is used in light metering. This is particularly im-
portant when using the panorama format if the scene
contains a wide range of lighting or tonal, contrasts.
 When objects are very close to the lens, remember that
their position in relation to the background will also be
subject to parallax and therefore, dependent on dis-
tance, will not be exactly as seen in the viewfinder This
effect is mainly of concern with the 30mm lens.
 Landscapes can often include a great deal of sky in
wide-angle photography. If pale in tone or with large
white clouds for example, such skies can affect the
exposure meter sufficiently to cause under-exposure
of the image. Dependant on the desired effect, take an
exposure reading from a more appropriate part of the
subject, excluding most of the sky, or use an external
exposure meter.
 Do not forget to remove the lens cap when
making an exposure !

Viewfinder eyepiece selection

The table below provides the choice of correction
eyepieces available in connection with an eyeglass
prescription. Firstly, decide which eye you would nor-
mally use for viewing. Then check your prescription
bearing in mind that in ophthalmic terms O.D stands
for the right eye and O.S stands for the left eye. In the
table, read off the appropriate eyepiece that is along-
side your prescription figures.
If your cylindrical eyeglass prescription is more than
0.5 dioptres, it is recommended that you always wear
your eyeglasses for viewing and focusing.
Please note that the eyepiece, including the correction
glass holder, is constructed from a rubber coated plas-
tic material to minimise the risk of scratching eyeglass
lenses.
