Lens mount
The camera has a breech lens mount not used from any other SLR. This type
of mount and the 50mm distance of the camera flange to film plane allow the use
of lenses of others 35mm cameras, via an adapter, for close-up only.
Diaphragm mechanisms
The control of the diaphragm is one of the main features in the lens specification.
It's important to understand the differences in the diaphragm mechanisms
to use correctly the Praktina lenses. Each listed lens has a code
that indicates the different diaphragm's feature.
NB (Normal Blende) Manual lenses
These lenses have a ring to manually close the diaphragm down to the wished
aperture. The diaphragm will remain close until it is reopened manually.
These lenses fit and work on all models.
BV (Blende Vorwal) Preset lenses
These lenses have a ring to set the diaphragm aperture to a preset value.
Before taking the picture turn the preset ring until it stops, which will
close the diaphragm down to the preset aperture. The diaphragm will remain
close until it is reopened manually.
These lenses fit and work on all models.
SB (Spring Blende) Semi-automatic lenses
These lenses have a ring to set the diaphragm aperture to a preset value and
a pin that engage with the internal mechanism of the camera. A cocking lever
opens the diaphragm manually to the largest aperture and set a spring mechanism.
The internal actuating pin of the FX-A model moves forward when the shutter
release is pressed, and the diaphragm will automatically close to the
pre-selected aperture.
The diaphragm will remain close until it is reopened manually.
These lenses work on FX-A and IIA-DA even if they fit on all models.
ASB (Automatic Spring Blende) Fully automatic lenses
These lenses have a ring to set the diaphragm aperture to a preset value and
a pin that engage with the internal mechanism of the camera.
The internal actuating pin of the IIA model moves backward when the shutter
release is pressed, and the diaphragm will automatically close to the
pre-selected aperture.
The diaphragm opens automatically when the shutter is cooked.
These lenses work on IIA and IIA-DA even if they fit on all models.
