    I own a Canon Rebel XT and I've been looking at the Sigma 17-70mm DX Macro
    as an general lens. I've noticed Quantaray carries the same lens that is
    obviously made by Sigma for Quantaray. The Quantaray lens is $200 cheaper
    than the lens carrying the Sigma brand name. If Sigma is the OEM for this
    particular Quantaray lens is there a difference between the two? Is this
    difference, if any, worth $200? All listed specs are exactly the same (as
    expected) and they are identical except for the where the "Sigma" should be,
    it's blank.

    Thanks in advance.

    I'll tell you why the Quantaray is cheaper. Ritz Camera contracts with igma
    for these lenses the same way WalMart squeezes their vendors. Make it

  3. I noticed that the Sony 18-200 lens has identical weight, minimum focus,
    Aperture range & number of blades, elements and groups etc as the Sigma
    18-200. Makes me wonder if the Sony lens is made by sigma, or if they
    are both made to the same formula, or if it is just a big coincidence...
