MAIN FEATURES

• The INON Z-240 is a high power strobe providing a guide number of 24 metres @100 ISO. 
• It combines this with wide angle coverage of 100 degrees which covers popular wide angle lenses for compact cameras including the INON UWL100 and UWL105 models or Nikon's DX12 - 24mm or Canon's full frame 17 - 35mm D -SLR lenses. This can be increased, officially, to 110 degrees using the supplied 0.5  diffuser. 
• Recycling time on full power is under two seconds.  
• It's this combination of power, coverage and speed in an ultra compact body that makes the INON Z-240 so remarkable.
• Three exposure modes are provided on the INON Z-240. TTL exposure operates with most compact camera systems and an increasing number of D- SLR housings using an INON fibre optic cable, renowned for their reliability. The TTL can be user adjusted to introduce deliberate under or over exposure for difficult subjects that can confuse some cameras TTL meters or for creative effect. Auto exposure uses the INON Z-240's built in light meter and can also be user adjusted for tricky subjects. Full manual power is also offered with 13 different levels of output available for very fine 0.5 stop adjustments to the exposure. 
• The Z-240 Mk4 is equipped with a newly developed ultra sensitive slave that can be used on auto, manual or TTL exposure.   
• A 3 Watt LED modelling light is built in with an auto shut off feature to prevent it appearing in your shot - it cuts out during the instant of exposure. 
• The Z-240 accepts a standard Sea and Sea Nikonos type synchronisation cord for connecting to most popular prosumer and D -SLR housings.
