Hey all,
I've recently bought the 50 AF-1 flash from Metz and I really enjoy using it. Since I am completely new to this I have a few questions that I hope you can answer to get me going. 
1. How do I trigger this flash with my 60D's internal flash?
2. When I set the flash to E-TTL HSS, will it then work with shutter speeds faster than 1/250s?
3. What is the lightning bolt button for? Upon pressed it just fires a long flash.
Thanks!
