Just to be clear I
am not a camera expert or dealer, I'm just helping an elderly friend
clean out his house so he can downsize. This is one of several
photography related items on offer.
Up for
auction is this nice used Vivitar Auto Thyristor 550FD N flash unit for
use with Nikon cameras. While I have not shot any photos with it, I did
try putting batteries in (it takes 4 AA's) and when I turned it on I
could immediately hear it power up. After a short time the ready light
came on and I pressed the test button and it flashed, so it appears to
work correctly.
Please see the photos to judge the condition for yourself.
