I'm looking for a flash with the following specs:
- Compatible with the A7 and the A99
- Powerful (good enough to use with a large fast zoom at a wedding)
- Long lasting battery
- Can be triggered wirelessly if necessary
- If possible...not very expensive
I can see my options with the new multi-interface are kind of limited http://www.bhphotovideo.com/c/search...07+4043133129&
What would you recommend?
