you must be referring to the SL960 - look mom, no D
it doesn't come with an optical cable and its brightness doesn't seem to be adjustable. otherwise, for 1/2 the price of a SL960D, i don't mind cutting the diffuser plate. i think it may be a good 2nd strobe to light the background with though - for e.g. as a slave to a SL960D or YS15.
i wonder why the distributor doesn't bring in the D version...? for less than usd300, it should still be a good competitor to the YS15. unless of course if the same distributor also sells the sea&sea...
please kindly PM me details of the company. thank you.
