Canon 5D and the EF 24-105mm f/4 L IS USM Lens.
Canon 430EX and the Olympus fl-50 Flashes.
Smith and Victor stands, lights and umbrellas.
Reflectors big and small. I have a small one I made out of aluminum foil and cardstock that I fold up and carry with me everywhere for bouncing a little light if I need it for outdoor stuff.
