I'm hoping that the experienced people on this forum might be able to offer some advice.
I finally decided to replace my Canon G9 travel camera, and despite some temptation from the new Sony DCX-RX100 I have gone for the Canon PowerShot G15. There are various reasons but I think for me it has the right compromize of size, features, useability and image quality for a travel camera. I have been happy with the G9, not as wide as I would like but there is always some compromise.
I would like to add a small external flash (with my G9 I only ever connected an Elinchrom Skyport trigger for studio flash (before I purchased my A900)). I like the design and dimensions of the Sony HVL-F20AM I use on the A900 when I don't want to take a large flash. The Canon flashes look a bit bulkier and I don't know if the independents offer anything that makes sense. And of course I want more power than the onboard flash but still something small and balanced.
Also, in the Canon world what would I do to take the flash off-camera?
