 
139Q with the 45mm Tessar "pancake"
lens and replaced leather covers
The 139Q was the second camera that Contax produced. It arrived
in 1979 and had Quartz timed shutter speeds and other functions.
TTL flash was also introduced with this camera. A 45mm f2.8 Tessar
was introduced specifically to mate with the 139Q and provide
the smallest top quality SLR in the world. Other new features
included an AE lock which stored the metered shutter speed, and
a faster flash sync (1/100th sec.). It is a nice lightweight
camera for use as a backup body or even a main body for non-professional
use.
