I got the new Sony flash tonight. It works flawlessly with the 5D so ( in theory) it would work with the 7D. These may not be prime examples, but it was my first time with a flash (other than onboard). It seems to give good results. BTW, I got the 36 model.

and 2 more.

There are two flash for Sony, which flash did you get? I was going to buy one today.

Sony HVL-36AM. It's the smaller one.
