The Sunpak Auto Zoom 344D is a classic versatile shoe-mount flash unit designed for use with 35mm film cameras.
It features an automatic thyristor circuit that allows for quick recycling and consistent exposure, making it suitable for various photographic situations.
This flash unit is equipped with an auto zoom function that adjusts the flash coverage to match the lens focal length, typically ranging from 28mm to 85mm, ensuring optimal illumination without wastage of light.
The zoom mechanism is manually adjustable, allowing photographers to tailor the flash coverage to their specific lens.
The thyristor circuitry enables it to regulate flash duration automatically, providing stable exposure and faster recycling times compared to traditional flash units.
It supports manual power control, usually from full power down to 1/16th or 1/32nd power, giving photographers flexibility in different lighting conditions.
Constructed with a durable plastic body and a tilting head, the flash can be bounced or directed to achieve softer lighting effects.
The shoe mount fits standard hot shoes, and the unit is powered by four AA batteries.
