Lenses and Mirrors

I'm having trouble getting this straight in my head, and am having difficulty finding what happens when an object and placed and different points around the focal length. I was wondering if any of you would be kind enough to help me document this in my head.

I have a good grasp what happens when the object is at infinity, or beyond the focal length in both lenses and mirrors. I also understand for concave mirrors, the image is formed inverted and real when the object is outside the focal length. And when inside the focal length, the image becomes virtual, upright, and enlarged.

Does that switch take place in convex mirrors, and concave/convex lenses as well when moving from outside to inside the focal length?

I'm know convex mirrors produce a virtual, upright image when outside the focal length (as do diverging lenses). Do they become real and inverted when inside the focal length? I feel like that could be wrong, but I'm having difficulty working it out.

No, the switch does not take place in convex mirrors. It is always virtual, upright, and smaller. Just use the mirror equation, except that focal length is negative for convex mirrors.
