Excerpt: this is my first autofocus 35 SLR. i never knew this thing exist at the first time. until i did some research about which Pentax 35mm SLR has more than one selectable focusing point. Why? because at that moment i was thinking, maybe i can make a better picture if i dont have too focusing and recompose at shooting. silly right? but yes. that was thing which always bogging my mind when i have to shoot 35mm SLR.
