Why Upgrade?
If you frequently shoot action, sports, liquid/splash, or need very fine power at low levels for close-up work, the Freeze durations, 1/512 output, and bi-color modeling lamp are the biggest practical gains. Multi-light users will also appreciate the faster setup with X3 one-tap sync and the group color indicators.
