Narowed down my on-camera flash for the A7RII to either the Nissin i60A or Godox Ving V860II. Nissin is extremely easy to use, but the Godox has super fast .7(?) sec recycle to full power due to it’s Li-Ion battery, vs 4, AA’s for the Nissin. Would need the Nissin external pack to reduce recycle time, negating the smaller footprint of the Nissin. Both have similar GN’s. Don’t have an information on the build quality of either. Any opinions would be beneficial.
