Summary: Want to light up a room? This is the flash. Unlike these add on flashes that are barely better the the on camera units, the HVL-F32X is a real flash with power to spare. The only drawbacks are nobody has made an adapter to use a Quantum battery so you can shoot all night without changing batteries and sunpak doesn't make an cord that will allow you to hook this flash up to a stroboframe. Shooting verticals causes the dreaded side shadow due to it's on camera mounting.
