Slr Lenses 101 Who Has Tried Using Olympus OM 101? (SLR)?

Who has tried using Olympus OM 101? (SLR)? - slr lenses 101

I had this very old SLR camera. In fact, my father. I have a class photo, why, because I do not have a digital SLR camera to use. I do not see the release button on my Olympus OM 101 I do not understand how the release button, since label, which says Lens 2 Lens 4 and target are 5.6. I do not know where the point of 3 smaller lines on the button.


And where can I find the ISO setting?
