Thanks to all for comments so far.
I appreciate that the flash unit can be set to 2nd curtain sync. However, I am interested to know why it can’t be set via the camera menu, as it is possible on other Canons, even the 350D. Do I have a malfunction, or am I in need of a firmware update? It would be great if someone could take a look on their 40D with a 430EX and see if they have any joy.
Go to menu ‘Spanner with 2 dots’,
down to ‘Flash control’,
down to ‘External flash func. setting’.
The top 3 selections are greyed-out on my machine (second one down being the needed ‘Shutter sync’
, with only the bottom 2 being active.
Many thanks if anyone can confirm success or failure with their 40D – 430EX combination.
