The Praktica LTL is an East German 35mm SLR camera with interchangeable M42 screw-mount lenses and stop down TTL metering produced from December 1970 to November 1975 by Pentacon
It has a vertical-run focal place shutter with speeds from 1s to 1/1000 + B and a self-timer operated by a rotating lever below the front-mounted shutter-release.
The meter is operated by a button on the side of the mirror housing, which is pushed back to stop down the lens and activate the meter. Film speeds for the meter are set by a scale inset into the top of the shutter-speed dial. The meter requires a Px625 mercury battery or equivalent; otherwise camera is entirely mechanical.
