We will be taking an Alaska cruise and land combination trip this summer, and I really do not want to pack my 430 EXII Speedlite, as my camera backpack will already be quite full. I am considering adding a smaller flash for interior shots of the ship, and shots of my wife and I on board. I would be using it on a 5D3.
I was also looking at the less expensive Speedlite 90EX, but that unit does not have a swivel head for bounce flash capabilities.
Are either of these smaller flashes worthwhile for my intended use, or should I just live with my wife's Canon S100 and my 7D's built-in flash for shots of us? I am planning on taking both the 5D3 and 7D anyway, along with 17-40L, 24-105L, 100-400L and 40mm f/2.8 pancake. My serious shooting is outdoors -- landscapes and wildlife -- and the interior shots will be more of the snapshot variety.
