I own two G40s and one G30. I will be doing a multi-day video shoot, during which I will have little time to swap out SD cards. I always shoot using the second SD card as a full resolution backup, so I need to max out the size of my cards for this shoot. The cameras will be plugged into A/C power - so battery capacity is not an issue.
Does anyone know the "actual" maximum card size these camcorders can handle, without any issues?
