Bill –
does not work with the original FJ400 strobe.
Its a great battery option to effectively double your strobe number for the new FJ800 and FJ400 II, DOES NOT FIT THE old FJ400. So another reviewer dinged it because it didn’t fit their fj400, unfortunately it was not designed for that older model.
