Thanks for all the comments. I do have the instruction/operation manual, but I think AgX has it right - you really need to study this manual rather than just read it!!
AgX - that's a big help. At least now I know that the viewfinder shows recommended aperture... I can work with that! Cheers!
I just tried out those exposure deviation buttons really quick as well... that seems like quite a handy method to use. I'll have to explore this further!
