I've been looking around a bit more at flashes. The real world has hit me pretty hard so I'm not in a hurry to buy anything, but I want to have some idea what I'm looking for when I get that straightened out.
Some flashes have TTL modes but no manual mode. What exactly does that mean to have no manual mode? It won't work on a K1000? There's no way to turn off TTL metering when used with my ZX-L, even if I have the camera in manual mode? I fear that sometimes light reflected from foreground objects will throw off the exposure, and manual mode would be best then.
