The Cullmann flash unit CUlight FR 36F is specifically designed for Fujifilm cameras and supports the AUTO TTL function. It is a compact, handy flash unit that is ideal for compact system cameras. The CUlight FR 36F integrates perfectly into the existing range of flash units with its product features. The number in the product name refers to the maximum guide number of 36 at ISO 100. The illuminated high-resolution LC display makes operating the flash unit simple and intuitive. The swivel reflector of the CUlight FR 36F can be tilted vertically (from -7° to -90°) and horizontally (270°), allowing for indirect flash photography. The extendable wide-angle diffuser for 14 mm illumination and the reflector card enhance its functionality. In strobe flash mode with a frequency of 1 to 90 Hz, effects can be effectively achieved. The CUlight FR 36F features an integrated 2.4 GHz radio transmitter and receiver, allowing it to be combined with the CUlight FR 60 in TTL or manual flash mode. Alternatively, both flash units can be controlled with the optional CUlight RT 500 radio transmitter. The CUlight FR 36F operates on two AA alkaline manganese/lithium batteries or NiMH rechargeable batteries. The package includes the flash unit with a case, stand, and flash diffuser.
