I have a Canon EOS 550d. I use as
- Canon EOS 550d + TT520 flash speedlite = works OK.
- Canon EOS 550d + off Canon shoe cord 2 = works OK.
But, when I use
Canon EOS 550d + TT520 flash speedlite + off canon shoe cord 2 = doesn't work
off canon shoe cord 2 cannot send signals to speedlite.
Is there anyone who has the same problem?
How can this be solved?
Camera firmware update is required?
