Yesterday I picked up a used Canon EOS Rebel X S at the Salvation Army for $10. It seems to work ok, but there was no instruction book. I know that many of you don't use film SLRs anymore, but I figured somebody would know how to use the feature on this camera. I have been using manual SLRs for years so I've got that stuff down. The thumb wheel on the left side is what I need clarification on.
M: shutter speed
Tv: Shutter speed and ?
flower: close up
On the right side there are two buttons, one is a star the other says Av +/- what does that do.
There are mode, select, and set buttons on the back, what are they for?
