German Mec 16 SB

The next technological advance came in 1960 when the German Mec 16 SB subminiature became the first camera to place the light meter behind the lens for more accurate metering. However, through-the-lens metering ultimately became a feature more commonly found on SLRs than other types of cameras; the first SLR equipped with a TTL system was the Topcon RE Super of 1962.
