    :confused: I have the opportunity to buy secondhand the Sigma 1.4 and/or 2.0 TC lenses. Has anybody any experience of these lenses? I will be mainly using it with the 70-300 G lens.

  2. Hi David,

    I have a Sigma 1,4 TC.

    1.- I don't know if it will work with the Nikon 70-300mm. With the 70-200mm and my Tamron macro lenses, it simply don't fit.
    2.- From my experiences with the Sigma 100-300mm, there's a slight degradation of image's quality when used wide-open. Stopped-down from f/5.6 (on the lens), there's no noticeable degradation.
