    Will extender work with macro lens?

    I have a Canon EF 100mm f2.8 macro lens (non IS), and a EF 1.4 mk3 extender. Can I use them both together to give extra reach for macro shots? I have a EOS 90D DSLR camera. I could try of course but am afraid of damaging the connectors if wrong.

    Canon EF 800mm f5.6 + 1.4x III extender with 1DX Mark II

    Hi Basic question - would an EF 800mm f5.6 with a 1.4x extender retain autofocus at the centre point with a 1DX Mark II? I can find this article here (https://support.usa.canon.com/kb/index?page=content&id=ART174703) that "1 series bodies" retain centre point AF, but 1DX is not mentioned? Thanks

    lens extender compatibility on RF mount

    I have an EOS R with the RF mount on the body and was wondering if I could use Canons 1.4x or 2x extender to place in-between the lens and the EF adapter?? has anybody done this and does it work with autofocus? if not does it still work with manual focusing? I want to use Canons mki 100-400mm...
