INON unique T-shape Twin Flash construction and optimally designed reflecting mirror/prism enable effective light distribution and produce powerful coverage without a diffuser.

More information

Minimum recycle time at full flash (how fast the strobe is ready to fire just after full flash) is approx. 1.6 sec. The Z-240 unique circuit components carries two sets of fundamental electrical parts (transformer and transistor) to achieve fast recycle time.

The Z-240 offers all advanced features including S-TTL Auto mode which supports TTL Auto exposure control by transmitting built-in flash light to an external strobe and compatibility with Clear Photo System. Optical connection system widely supports from transparent housing for compact digital cameras to a housing for digital SLRs with built-in flash regardless of make or model. Its sync connector accepts Nikonos 5 pin type cable to shoot in TTL Auto mode with a film camera or in Manual/External Auto mode with high end digital SLR not equipped with the built-in flash.

It is simple to fine-tune flash power in S-TTL Auto by dialing the EV Control Switch on the back control panel. Adjustable range is 3 steps to increase and 6 steps to decrease, to suit to personal preference or different exposure control characteristics among camera models.

The Z-240 Type 4 successfully amplifies receiving optical signal from the slave sensor 20 times more comparing to previous Z-240 Type 3 to provide wireless S-TTL Auto mode using a mirror instead of an optical cable. Attaching optional Wireless Connection Kit on the Z-240 Type 4 and combined with a housing via Shoe Base Set or Grip Base D4 Set creates a handy S-TTL Auto shooting set.
