Kalart Automatic Synchronizer – Speed Flash

A classic piece of mid-century photographic hardware, this Kalart Automatic Synchronizer was designed to mechanically synchronize flash firing with a camera’s shutter — a clever solution from the pre-electronic flash era.

Housed in a solid metal body with its original identification plate intact, this unit connects between the camera shutter release and a flash, using an adjustable mechanical linkage to ensure accurate timing. It was commonly used with press cameras and early flash systems, making it an authentic period accessory for collectors or large-format / vintage camera enthusiasts.

Key details:

• Automatic mechanical flash synchronizer

• Designed for use with speed flash systems

• Sturdy all-metal construction with adjustable cables

• Made in USA by Kalart

• Visible patina and wear consistent with age, adding to its vintage character

Ideal as a functional accessory (subject to user testing) or as a collectible display piece alongside classic press cameras and flash equipment.
