Would like to get into flash photography
Start out with the strobist web site and go from there. You have to decide what you really want to do with flash to decide on a path.
With the on board commander and a dedicated Fuji flash you can do off camera flash pretty easily indoors, don't know how well it will work in strong sunlight. Tends to weaken the signal since the off camera flash is triggered by a series of flashes from the camera.
With some cheap Nikon or Vivitar flashes and cheap Chinese radio triggers you can work on manual off camera flash.
With Alien Bees and triggers you are now up to studio level working with models and such.
Do a little research before you drop any cash and see what will work for you.
