    Hi Brit!

    A macro lens is used to increase the focus of a camera.

    Considering this, does the focal length of the lenses have to be positive or negative for the camera's focus to be maximum? As a reminder, a diverging lens has a negative focal length.

    I'll let you complete the problem with these clues. :)

    Here's a sheet to review if you need more explanations or examples:
