I'm wondering what power flashgun people like to carry in their general gear bags: the bag you grab when you're heading out the door to photograph a bit of "this" and a bit of "that."
I have (Canon) 90, 430, and 600 flashguns. The 600s are a bit heavy. I'd rather not add one to my "on the go" bag. The 430 is okay, but still a bit more weight then is ideal. The little 90 is very small and portable, but I suspect it doesn't have enough oomph for bright and sunny days outside. It has been cloudy today, so I couldn't test them. My on-the-go lens is my 24-70.
I wound up doing an impromptu portrait session yesterday, late in the morning, and the sun was brutal. I would have given my eyeteeth for a flashgun.
Which size flash should I make sure I have in my bag at all times?
