G12 Bug: Self Timer Shutter Delay with Wireless Remote

.
Another flash related bug has shown up on the G12. Previously, I griped about the “screen blanking” that occurs when using a (non-Canon) wireless remote to trigger an off-camera flash. Even though the screen would go dark (indicating the manual exposure) with wireless remotes, at least the flash would be triggered. A recent discussion forum thread pointed out that the flash will not be triggered if the internal self timer is used to produce a shutter delay.

I tested my own G12 using Yongnuo RF-602 wireless remote triggers connected to off-camera Canon flashes. The RF-602 triggered the flashes (although the screen went blank) as expected unless the G12 self timer was used to delay the shutter.

The problem was also reported to occur with CyberSync CST remotes.

Apparently the mis-fire does not occur with Canon’s own STE-2 transmitter and Canon flashes.

A work around for self portraits is to add a second RF-602 transmitter and receiver (set to a different channel) along with the Yongnuo shutter connnecting cord LS-02/C1. I did this to get some Halloween pictures.

The G9 does not have this problem – something has changed in the G12 firmware. C’mon Canon, fix our G12s!
