    Sigma Art Video AF with new Firmware

    Has anyone tried the Sigma Art lenses which have just received a FW update (I believe 2.0) from Sigma in video AF yet?

    Although not specifically mentioned in the FW update, there have been widespread reports/confirmations that this update fixed long-standing issues in Canon live view DPAF, so there is a high possibility it may have improved video DPAF too.

    I don't have any SA lenses to test myself, as I'd always been put off by possible AF issues, but this sounds very promising!

    [N.B., will also post this in the C-series forum, as it's relevant there also.]

    I never really noticed any issues with my sigma art lenses on my 5D IV. I've used the 20 1.4, 35 1.4, 50 1.4 and 150-600C All seems to work as expected.
