    Whats the difference between the Sigma:
    70-300mm F4-5.6 APO DG Macro
    and the
    70-300mm F4-5.6 DG Macro? (NON-"APO")?:confused:

    I recently bought the APO version for my Canon rebel then saw the Non-APO for $50 cheaper... Whats the difference and did I buy the right one?:meh:

    The APO edition is the newer of the two lenses and is an upgrade of the older lens. The APO coatings on your lens give an overall improvement to the sharpness of the shots you can get, this is very helpfull at the longer end of the lens (200-300mm) where it generally goes abit softer.
    You made the right choice - no go forth and shoot :)

    This is what Sigma define APO

    "In order to attain the highest quality images, the APO lens has been made using special low-dispersion (SLD) glass and is designed to minimize color aberration."

    In other words, it is better than the one without. Whether it worth the extra $50 or not. For me, I will go with the one with APO if I need to choose between the 2 now.
