Praktica's common budget M42 SLR — the MTL3, stop-down CdS TTL, manual exposure, 1978.
The Praktica MTL3 is a 35mm film SLR made by VEB Pentacon in Dresden, East Germany, from the late 1970s as part of the MTL branch of the L-series. It was a simplified, cost-focused metered body sold in very large numbers, becoming one of the most common East German SLRs on the UK second-hand market and a familiar entry point into M42 photography.
It is an M42 screw-mount SLR with a vertical-travel metal focal-plane shutter offering speeds to 1/1000 plus B. The MTL3 has a battery-powered CdS through-the-lens meter operated stop-down, matching a needle in the pentaprism finder after closing the aperture with a lever. Exposure is manual only; the shutter is mechanically timed and works without a battery, while the meter requires a cell to give a reading.
The MTL3 suits students, beginners and anyone wanting a robust, cheap manual SLR to learn exposure on. Its handling is basic but dependable, the body is heavy and solid, and the vast supply of inexpensive M42 lenses makes it economical to expand. The dim finder during stop-down metering and the lack of any automation are the usual limitations to expect.
Buying used, confirm the meter responds with a fresh battery and be aware it was designed around a mercury cell of about 1.35V, which affects accuracy with modern replacements. Test all shutter speeds for capping or a slow curtain, and inspect the foam light seals and mirror-damper foam, which routinely perish on these bodies. Check the prism for desilvering, the advance and rewind for smooth operation, and the stop-down lever and focusing screen for correct function.
