Canon will tell you that compatibility with third-party lenses is no concern of theirs. You will need to contact Sigma to see if they have an update for the *lens*.

Sigma can update just the firmware in the lens, you don't need a new one. If you have the USB lens dock you can update it yourself, otherwise you have to send it to Sigma.

"I can write to canon support to inform and looking for a software update"

 

That won't help !  Canon doesn't support third party lenses.  I doubt it is a firmwasre issue but you might try calling Sigma.  Good luck.  I haven't used the Siggy in question but not all SIgma's can be updated by the dock.  I suspect your is one that can not. It's worth noting that lens correction options and other camera functions on the latest DSLRs generally don't work with third-party lenses.  You may want to return it and buy a real deal Canon lens, perhaps the very good EF-S 55-250mm f/4-5.6 IS STM Lens.

EOS 1DX and 1D Mk IV and several lenses!
