Praktica LTL Instructions for Use
– 11 –
It the cocking lever – as described above – could not be fully cocked, this must be completed, and
the shutter released, after the usual rewinding procedure and before a new film is inserted.
N. Exchanging lenses
The standard lens of the PRAKTICA LTL
can easily be replaced by lenses of other
focal lengths or apertures. You take hold of
the lens body, as shown in the illustration
opposite, and turn it in an anti-clockwise di-
rection. The exchange lens is inserted accor-
dingly and screwed tight by clockwise rota-
tion.
All lenses having the international PRAK-
TICA screw fitting M42×1 may be used.
Only some of the older types of lenses are
not suitable because of their structural design
(please refer to Section H).
