Nikon D90 and SIGMA EF-530 DG ST SUPER
I consider myself as a novice photographer and I'm looking for an external flash for my new D90 (+18-105mm). Since my budjet is limited, I was wondering if Sigma´s EF-530 Super is a good choice? Price for that flash atm. is 199€, whereas Nikon SB-600 costs about 250€. The feature I'm looking for is high speed synchonization (FP flash), and it seems like Sigma has this feature. Also using it remotely with the integrated flash should work. So, any recommendations? Should I buy the Sigma or save a bit more and go for the SB-600?
