Hi guys, i need some expert opinion: i recently bought my first full frame DSLR D610. i am looking to buy a speedlight (flash) and confused between nikon, nissin & Yongnuo. Considering that i have no experience with flash photography, which brand and which model i should go for in your expert opinion? i mostly shoot my non stationary kids indoors / outdoors or in the malls.On the budget side, something around a 1000 aed would make me feel happy to see nicely lit pictures. Lastly, is there a proper photography gear shop in abu dhabi apart from sharafdg, emax, grandstores? Thanks in Advance. Syed
