    I am new to photography and just purchased a Kiron Macro 105mm, f/2.8 Lens from ebay for $265.00. I found information on the lens at, but I'm a little confused.

    Can anyone tell me about the numbers (32,16-16,32) on the barrel to the right of the reproduction ratio?

    I'm guessing this is for Nikon. is it manual focus or autofocus?

    All that I can offer you is this Google Search

    And/or look around the Flickr Group: No metering lenses on Nikon DSLRs

    Edit: Depth of Field markings I'm guessing since after having a read/look at "since depth of field is so small at high resolution ratios, a lens opening of no larger than f/16 is recommended."
