after doing some poking around on strobist I am considering the Sunpak 383 flash or the Vivitar 2385HV for our D40 along with the Cactus 4 channel flash trigger. what i want is a good on camera flash that will work with the D40 with little to no messing around with manual settings on the flash as well. of course i want the ability to manage the settings on the flash, but i dont want to have to every single time necessarily, so auto syncing with the cameras settings is a huge plus. i also want to start trying some off camera flash work, hence the Cactus. my questions are: will either or both of these flashes work with the Cactus 4/D40 setup? will either or both of these flashes work on the hotshoe of the D40 without having to manually adjust the settings on the flash? and finally, it doesnt look like the Vivitar turns left and right but the Sunpak does, can anyone confirm this? or should i just get the SB-600 instead? or am i really, really lost and confused on all of this?! tia!
