    1.4x tc you lose 1 stop on the widest lens aperture
    2x tc you lose 2 stop

    Calculate yourself and only 1series canon body that can AF on f8 widest aperture lens

    Some photographers tried to fool the non 1 series camera by tapping the tc pins. It works but it hunts madly. You do it often, good luck with the AF motor

    You can use kenko tc. Use a TC1.4 else it is too slow.

    I have the Kenko Pro TC 1.4, and it works fine with Canon bodies and Sigma lenses, and you don't have to tape the pins. IQ is comparable to Canon ones.
