Hi!
I've decided to use optical triggers instead of radio triggers as my first step into flash territory.
I have a 580EX which works well with my 420EX.
I also have a Nikon SB-28 and SB-28DX (too bad they weren't SB-26 with built-in optical triggers!).
What are good optical triggers for those that can be bought at Adorama or B&H?
Thanks!
