Elinchrom steps into the TTL arena with the introduction of the ELB 500 TTL battery-powered pack. Measuring 6.4 x 7.12 x 3.6" and weighing just 5.5 lb with its separately sold battery, the ELB 500 is ideal for the traveling or location photographer shooting fashion, portraits, or editorial work. Using an optional Elinchrom Skyport Pro or the Phottix Odin II transmitter, the ELB 500 TTL greatly reduces setup delays, shortening the time between inspiration and execution by using your camera's flash exposure system. With asymmetrical power distribution over 7 stops to 2 ELB flash heads, photographers can make TTL power adjustments at distances from 328 to 656' depending on the transmitter they use. There's also a Manual Lock mode that allows you to get a TTL initial exposure "lock", and subsequently switch to manual mode to fine-tune exposure.
While the ELB 500 TTL outputs about 10 times the power as a speedlite, it has features that you'd only find on an advanced on-camera flash. The pack is High Speed Sync compatible, for example, allowing you to trigger it at shutter speeds as short as 1/8000 sec to control background brightness, freeze action, or to use wide lens apertures.
These advanced exposure features are backed by solid performance specs. Recycling is a very fast 0.05 to 2 seconds and flash duration is 1/3400 sec in Normal mode. There's also an Action mode with flash durations as short as a lightning-fast 1/20,000 sec - ideal for freezing water spray, splashes, and other effects.
The ELB 500 is powered by a separately sold removable lithium-ion battery that will give you 400 full-power flashes and an impressive 28,000 minimum-power flashes on a full charge. Convenience features include Active Charging, which allows you to charge the battery while shooting with AC power for an uninterrupted workflow. Power, performance, and TTL exposure control make the ELB 500 TTL hard to beat.
