I'm about to upgrade from my umbrella to a softbox, and I'm thinking about getting the 28" Apollo by Westcott. I'm going to be shooting with manual flash instead of E-TTL because I have two 580's and am using the Cactus wireless system. With the way this softbox is designed (flash is inside the box shooting toward the back), is it going to be a huge pain to have to reach in there and change settings? I can't change the setting via the camera's back menus because my camera hotshoe is actually connected to the Cactus (via a cable) instead of to the 580. Is this just what you live with when using a softbox? Is it not that big of a deal? Thanks!
