Know the feeling ... but the standard reply about flashes at the moment tends to be ... not Nikon (or Canon / Sony / etc) but buy Godox. Not the cheapest but a versatile system. Buy once, buy right...Not only would I like that zoom lens above, I would also love a flash gun. I borrowed a Nikon SB 900 and after using it, I wanted one. So many camera related stuff I want, but too many household bills and limited cash.
