AF200T or AF280T are what you need. ($20 or $50 are good prices) Either one works with the Super Program to give TTL flash, ie flash is measured IN the camera by a sensor not in the flash. It gives great flash photography as you change lenses. The AF280T is really nice, tilt, swivel, & bright. The AF200T has no bounce head and is a bit less powerful. Regards, Bob S.
