The Foba TURAN-B Fitting for Broncolor Ringflash is an adjustable fitting that hosts a ringflash from Broncolor. The fitting is an accessory for Foba's TURNA turntable.
TURAN-B attaches to a steel shaft (either TURSA or TURSU), whose inner shaft turns (for example) a TURTE acrylic plate while its outer shaft remains stationary, keeping the ringflash in place. This ensures even lighting during the rotation of an object that is being photographed.
Note: All mentioned items besides TURAN-B are available separately.
