43 Ltd, K100D, some strobist info... um... AF280T through an umbrella high left, cactus trigger, AF200T on a light trigger on the right straight on the cameras (you can see the shadow from the folder legs).
A clean studio/product shot. The only thing I'd offer is to maybe seperate the subjects phyiscally. THis may not play well with your DOF but could be worth a try.
