Mainly, what are the settings for my Canon 30D and Sigma 12-24mm?

How about on the EOS500N film SLR?

I just got all my stuff and used to do my stuff hand held and normal tripod, so am new to all this.

edit: All my other lenses I plan on using with this is an Adapted Olympus G.Zuiko 50mm f/1.4, E.Zuiko 135mm f/3.5, and Tamron Adaptall-1 M42 200mm f/3.5
