Hi! I have a Nikon D7200. I have never bought lighting equipment before (all I have is my camera). I shoot dance action shots and different types of portraiture. I am looking to buy some lighting equipment to better my photography & take photos inside in a studio setting. I am also looking to expand the types of photographs I take to more editorial portraits and high fashion portraits. What lighting equipment should I buy to get started? I am looking at buying these products...What do you guys think?: speedlight attachment for camera & a portable softbox for the flash standing speedlight or stationary light ... umbrella or softbox diffuser? 5 in 1 round reflector Flashbender reflector Thank you so much in advanced!
