| Well, the TTL means Through the Lens metering, which you can pretty much forget about since it's a 15 year old flash and only worked that way with certain cameras. M means manual, which is your best bet. ISO is where you set the speed of the film you're using. Then when you focus on your subject and read the distance off the lens you can match up the aperture setting using either the green or red line (I have no idea what the difference is).
I don't know for certain what the rest means. Does it even work? Flashes age, and that is ancient for a flash unit. |
