PDAF does work with the Sigmas, but only in the center.

I don't believe it does. My 30mm Touit does not support PDAF,

But Tomtom50 wa talking about the Sigma, not the Touit. The Touit needs a FW update that must be done (free of charge) by Zeiss.

There is no firmware update available at this time for the Touit.

No they will be in August, sorry confused it with the FW for the X mount

yet in AF-C mode with Wide focus area, I get flashing green squares in the Center AF area. Clearly this does not show that PDAF is available, because everyone agrees the Touit does not use PDAF. From your description, the Sigma acts the same way.

I've read a lot on this forum that Sigma lenses only use PDAF on the centre point...

Then I would say they are confused, as TomTom50 is, but the flashing green squares in AF-C mode, Wide zone focus.

PDAF ONLY works with the centre PDAF point, so it make sense it will not work in AF-C or Wide zone, as there you need all the PDAF points.

It the Sigma allows PDAF, then show me how it differs from the Touit, which clearly does not allow PDAF.

See above. Touit will after the FW update...
