                    My D2 is acting weird after updating to firmware version B1, what should I do?

                    Why is the D2 the world's fastest monolight with TTL?

                    How much power do I need?

                    Can I change the orientation of the display?

                    Is the D2 suitable for packshot photography?

                    I normally travel to various places in the world, does the D2 work globally or do I need a special version?

                    I have weak electrical power supply in my studio and sometimes I use the BatPack. Will the D2 kill the fuses since it has super-fast recycling time?

                    Can the D2 monolights freeze motion? What recycling time is required?

                    What are the differences between B1X vs a D2?

                    Why should I choose the D2 instead of the D1?
