• The unique ergonomic design of the Profoto D4 Generator is a combination of accurate electronic technologies and encouraging feel of mechanical switches and knobs.  Hence enables accurate control in the increments of 1/10 f-stop
• Since the outputs are digitally controlled, it ensures that the color and flash temperature stays consistent always
• You can achieve highest power stability from flash-to-flash and without f-stop shifts
• Photographers would be able to adjust the light from the control panel without requiring the lamp heads to be unplugged and re-plugged
• This generator is highly compatible with a wide array of Profoto accessories and lamp heads
• The secondary functions like delay, intervalometer, and sequence of these generators can make even complicated lighting setups very simple
