I've got already 3 x 580EX but i'm wondering about purchase some strobes.
I've selected 3 possible choices that perhaps emblematizes 3 different approaches to the "need for power" (overpower the sun, large group or ambient, nightime formals...you name it).
Here there are:
3 x Qflash TTL X5DR
3 x Battery Module PB2
3 x 200 W/S Add-On Module
3 x QPAQ-X - 200 Watt/Second Power Pack and Command Module
Fast Charger for QPAQ-X
3 x 400 Watt Second Next Generation Power Pack
3 x 800 W/S Flash Head
3 x Large Battery Module
Quick Trickle Charger
2 X Elinchrom Ranger RX Speed AS Asymetrical 1100 Watt Second Battery Operated Power Pack Kit, with Freelight A Lamphead, Battery, Charger & Sync Cord
What would be your choice and why?
