A B800 and a B400. The 400 has trouble lighting anything above F/8 at 100 ISO. Where as the B800 has little trouble going to F/13 on my camera. I'm completely new to portrait/studio lighting so this should be fun. I also got a Cokin Z grad kit, graduated blue, tobacco, and ND2. Got a 52 and 77mm adapter ring. After thinking about it now, I can't think of many scenarios I would even use these graduated filters on a 50mm prime. Kinda of stupid, oh well. A quick shot while runnning back to the office at lunch. And finally something to trigger the Alien Bee Slaves (that sounded funny) SG-3IR. Was just using a 58mm IR filter taped to the front of the built in flash before to trigger the speedlights. This works better and the Alien Bee slaves have not failed at all even with the camera placed in front of a 48" octobox.
