Jesse....I am going to give you way too much info....but here it goes...:z04_whis_gummikau02
I shoot Sony and Sigma....I have 8 Sigma flashes....
1 x 530DG Super
2 x 500DG
4 x 500DG Super
Differences....500DG Super 28-105mm and 17mm with defuser down...530DG Super 24-105mm and 17mm with defuser down.....the 530 seems to cycle faster...and I can get three consecutive shots off with it...vs the 500 at two....you can push the flash to 4 to 6 but they will overheat...:z04_headbanger:...I have done that to one...LOL...I still have it...and keep it just a reminder...
I use the DG as cheap flashes when I go out and about...they work well but only on camera...I have all the Supers due to the fact that I can use them as off camera flashes and have them all communicate in CO SL mode...which lets all the flashes communicate...and fire...I have had some miss fires every now and then...but nothing bad...I looked into getting a large Bantam Battery for them...but found a good set of NiMD's and a Maha-Charger work better....I keep two sets of NiMD's for each flash and get between 175 to 250 flashes on each charge....2300Mah
Usually I use the 530 as the commander and the 500's as slaves....I also use a Coco Ring adapter on the 530 when shooting this way...
Either works good...and I have enjoyed both...
Ok I know your gona ask why do I have 8...LOL....
This diagram is not mine I took it off the internet..and made it work for my needs....

Strobe C & D are on 4 foot stands either pointed at the wall behind the person or up...with defusers on them..white/blue/yellow...depends on what the person is wearing...usually 1/8 speed f4 or f6...flahses set to CO SL mode
Strobe A & B are on the floor....pointed up at the shoulders...usually 1/16 f8...flashes set to CO SL mode
Then camera has the ring flash adapter..and it is TTL...also the commander...
Like I said way too much info...hope it helps....with two flashes...I would put one on the body..commander and one with a defuser to the person Right or Left....just behind them...pointed at them...to kill shadows...
