Sigma EF-530 DG Super Electronic Flash for Nikon DSLR

Do yourself a favor...spend the extra $50 and get the Nikon SB-800 instead. I initially bought the Sigma EF-530 DG Super as a lower-cost alternative to the Nikon SB-800, and I regret it. I ended up buying the Nikon SB-800 after all.

Any way I use this flash, either standalone on-camera, wireless master or wireless slave, I have to make manual adjustments to exposure because it always over exposes. In addition, as a wireless master, it often miscommunicates with the slaves, resulting in slaves firing at full power, not only over-exposing the subject, but also wasting battery life.

To setup as a wireless slave, you must first attach the flash to camera, make your settings, then remove it from the camera. Then if you turn off the flash or accidentally press the "mode" button, you have to re-attach it to the camera and make all you settings all over again. Such a hassle. In comparison, the Nikon SB-800 or SB-600 can be setup as a wireless slave without having to attach the flash to the camera, and when you turn the Nikon flashes off and back on again, all the settings are the same a you left them, so they're always ready to go straight out of the bag.

One more thing, the menus on the Sigma are very cumbersome and not very intuitive.

Bottom line, if you're only ever going to use this flash as a standalone, and having to play with exposure settings is worth saving $50 to you, then you might be okay with the Sigma EF-530 DG Super, otherwise go with the Nikon SB-800.
