  • Works as expected on my Canon 5D miii

    Do not expect it to fit every lens. However, it works great with my 70-200 f2.8 lens, cuts the f-stop in half - nice to be able to zoom up to 400.

  • Does not fit all lenses and cameras
    Verified Purchase

    It fit my DSLR, but not my two lenses.
