The 50" Westcott Apollo Softbox is a great light shaper. Of all my light modifiers, I like the 50" Apollo the best. I use it with studio flashes and torches. Single 580EXII, I can get about f5.6 at about 40" and it gives quality window light! Love the control I'm using of this softbox, it's well recessed and makes it very easy to mix the light.The main downside to this Apollo is that you can't get a great angle on the box with a standard stand.I use an offset clamp from Paul C. Buff "BABY BOOMER". ] I would recommend this softbox to anyone who loves beautiful light!
