SQ-A
Congratulations on your choice of the Bronica SQ-A single lens reflex camera that has been
developed to give you quality performance, simple handling convenience and extremely
useful versatility, such as required for professional photography.
The Zenza Bronica SQ-A has been designed to take full advantage of the square 6cm x 6cm
medium format. It has also been developed as a complete modular "system" camera, with a
very high degree of interchangeability in lenses, finders, focusing screens, film backs, etc.
To obtain best results from your camera, we suggest that you read this instruction manual
carefully, before you even touch the camera. Thoroughly familiarize yourself with its work-
ing parts, before loading your first roll of film, and your pleasure in using the Zenza Bronica
SQ-A will be even greater.
NOTICE
Although instructions following are based on a standard combination consisting of the
main camera body with standard lens, film back SQ 120 and waist level finder, the choice of
lens, film back and finder is left to the discretion of the photographer, who should choose
those items best suited to the type of assignments contemplated.

But, if winding is possible, rotating the film winding crank until it stops will automatically take care of the incomplete action, even if the shutter is uncocked or film is not advanced. Thus, it's always possible to choose the film type most suited for the shot, even midway in the roll.

  • Page 24: Care Of The Sq-A

    28. Care of the SQ-A Restrict cleaning of the reflex mirror to blowing or brushing with the blower brush or a soft camel hair brush. Don't touch the surface with your fingers or a cloth. Use lens cleaning tissue and liquid to clean the surface of the lens. Do not use silicon-coat- ed cloth for this purpose, as it will prove detrimental to the lens coating.
