Thread: teleconverters

    Default teleconverters

    I've read that quality is compromised when lenses are coupled with a 2X teleconverter, how true is this? Is it true then that a 1.4X converter will not compromise much of the quality?

    I'm using a Sigma 70-200mm on a 10D, would it be better to get a sigma converter or a canon one? Anyone knows the rough cost?

    Thanks!

    As complexity rises, precise statements lose meaning and meaningful statements lose precision.
