Hi everyone! I have just obtained a Mamiya 330f (what a beauty!) and I also have an old Graflex 22 (that my son has taken an interest in) as well as a few very old 35mm's that I like to shoot with.
So, I'm looking for a good but simple and cheap ambient light meter that I can I use with my old cameras and I'd like to teach my 8 yr. old son to use it too. Any suggestions?

Thanks in advance
