OConnor Rosette Adapter

OConnor fluid head platforms carry four handle rosettes, and most of the time three of them sit unused. The C1249-1000 rosette adapter turns any one of them into a general accessory mount, which is a neater answer than clamping a rod or a magic arm to the tripod leg and hoping it stays where you left it. It fits current and legacy OConnor heads.

On its face it carries a 3/8 in 16 thread, 1/4 in 20 threads and a 60 tooth rosette, so it takes monitors, handles and lens drive controls from the usual accessory brands directly. It is small enough to leave fitted permanently: 1.25 in (32 mm) wide, 1.25 in (31 mm) high, 2.5 in (64 mm) long, and 0.2 lb (0.1 kg).
