The Praktica super TL of 1968 can be considered as a simplified Prakticamat, still based on the nova chassis. Instead of the elegant but expensive TTL metering arrangement as used in the Prakticamat, it uses a small metering cell reading the light bled off the front surface of the pentaprism, where an additional prism known as Light Concentrator is added: all M42 Prakticas with TTL metering except the VLC inherited this metering layout. Theoretically somewhat more prone to influence by stray light entering through the eyepiece, it nevertheless works very well, and with the added benefit of being centre-weighted in its metering pattern.
In line with the nova models, the super TL has its shutter speed dial returned to the conventional position, and its top speed reverts to 1/500s. At this time the customers were no longer likely to have to use early lenses with greater body intrusion, so the automatic diaphragm actuator is no longer disengageable. |
