Congratulations on your choiceof the Zenza Bronica EC-TL single lens
reflex camera which offers the user tb quality performance, handling
convenienceand versatility required for professional-classphotography.
The Zenza Bronica EC-TL is a camera which you can be proud of and
which will justify your choice. It is a real "system" camera with a
very high degreeof interchangeability (lenses,finders, focusing screens'
film backs, etc.), 8s well as a built-in TTL (thru-the-lens) exposure
meter systemwhich can be used for fully automatic exposureoperations.
At the same time, however, there is complete manual override of the
automatic exposuresystem, as required by professional'users.
To get best results from your camera, ffi&y we suggest that you read
this instruction manual carefully, before you even touch the camera.
Thoroughly familia rize yourself with its r,vorking parts, before loading
' your first roll of film, and your pleasure in using the Zenza Bronica
EC-TL will be even greater. ,
