The Einstein E640 is Paul C. Buff’s top-of-the-line monolight strobe. Key features include:
Dedicated function and adjust buttons
9 f-stop power variability
Two unique operation modes
Precision Controls. The Einstein E640 features all-digital control from a 2.4-inch high-resolution LCD. Gone are the days of the slider-bar. The dedicated function and adjust buttons afford you precise, 1/10 f-stop control.
Power Variability. This unit offers a welcomed 9 f-stop power variability that allows light adjustment from 640 w/s all the way down to 2.5 w/s. It has a quick recycle time of 1.7 seconds at full power, and dramatically increases recycle as power decreases.
Two Operation Modes. There are two operation modes that allow you to control what’s most important based on what you’re shooting. In Action Mode, the flash duration is minimized for maximum action-stopping capability where absolute color consistency is secondary to motion freezing. In Constant Color Mode, the emitted color temperature is held constant at 5600ºK (+/- 50ºK at any power setting or input voltage) and the flash duration fluctuates.
High-Quality Build. The frosted dome cover reduces UV emissions while protecting the bright, voltage-controlled 150 Watt modeling lamp and UV-coated, single ring flash tube. The strobe features both audible and visual recycle indicator alert options for shooting away from the unit. The built-in fan allows for cooling the unit during heavy use. It has a standard 1/8-inch sync-port and is fully compatible with all our AlienBees modifier accessories.
Mount it on a light stand and you'll be good to go!
