I am thinking about upgrading my 430EX flash for my 5D Mark II. I am looking for something with more power and the ability to control my 430EX off camera. I am an enthusiast who shoots portraits and a few weddings.
I was pretty sure I was going to get the 580EX II until Canon announced the 600EX-RT.
option 1: Buy a couple of used 580 EX IIs
I know the 580 EX II can drive my 430EX. I read one user say that they keep one on the camera and one cooling in a bag and just switch them out when one overheats. Seems like a good idea. However, I wonder if the money is better spent investing in the radio technology of the 600.
option 2: Buy a 600EX-RT
I have read several posts on this forum talking about the 5D Mark II's limitations with the 600EX-RT and I am confused. I think the 600 will work with the 5DII for basic on camera flash and basic off-camera flash, is that right? I understand that I can't use "in camera" controls, but I don't think that is very important to me. Can I still control a group of flashes with it on the 5DII using the flash's menu? Can I trigger some flashes optically (like my 430EX) and some through radio like the 600 (or 440EX)?
Thank you very much for any help you can give me.
