    what does APO mean in reference to a camera lens?

    APO is short for the word "Apochromatic." With normal lenses, you can sometimes get what's called a chromatic aberration, which is basically a mess up in the photo that's caused by the fact that different colors of light focus at slightly different distances. An apochromatic lens is engineered so that all colors of light focus at the same distance. This is particularly useful with infrared and UV photography. Apochromatic lenses are invariably of better optical quality than regular lenses because of this, which is why they tend to be more expensive.

    It would be worth around $300 to $400 depending on condition (if you can find one 'cos there's not a lot about).
