I have not run into any problems with any diffuser. Use it with soft boxes and umbrellas (72"). Works just as easily with my modifiers as the Canon flash. I wish I could afford two more. I should probably sell my Canon flashes to get them. I really am that happy with the Streaklight.LDS said:While very portable, such units may limit you in the diffusers choice, especially the larger ones. Unless you need easy portability and outdoor use, I would use a studio monolight.CanonFanBoy said:Honestly, if you plan to use flash at all I would get the Flashpoint Streaklight from Adorama. The non-ETTL version is going for $299 right now and = 5 or 6 Canon 600s as far as power goes. The light is very good. I have 7 Canon 600s and have not used a one since getting the streaklight. Very good for outdoors too.
On sale right now for $249. wow.
