This camera will not finish it. A single-pin \/ X-sync gun still pops \u2014 you set power, the leaf shutter does the rest. HSS exists to pulse a tube through a focal-plane slit. There is no slit here.

Lux Junior (GN 12, 7 steps, 28 mm fixed, 130 g, 2\u00d7 AAA, S1\/S2). Skip TT350P as the automation pick. Skip a V1S-class head on 32.7 mm of camera.
