I have a Hasselblad flash question or two.
For studio and location work I use Profoto D1's with my H4d-40. Pretty simple to sync at 1/800.
Now I am looking for a portable, lightweight high speed flash setup beyond the built in on-camera flash. Would be used for travel or as a lightweight option to my D1's and battery pack. I need recommendations on a flash unit and radio triggers to give me the highest sync speed possible. My understanding is there exist synch speed limitations with some triggers.
