durations: 1/400 sec. (full power); 1/800 (1/2); 1/1600 (1/4)
power source: Sunpak CL-3 battery, 4 ‘C’ batteries, battery pack
price: $197 (Adorama) $120-180 (eBay)
pros: powerful, different heads available
cons: bulky (huge with battery attached), expensive
overall: A very powerful and versatile flash, but probably too bulky for its own good. I would buy 2 Sunpak 555’s instead, they are half the cost and almost half the size, and when doubled up overpower a single 622.
