I've just registered to tell how shocked I am with what is going on with those two lenses - tokina 11-20 f2.8 and sigma 18-35 f1.8 - not working for so long...
From my point of view Blackmagic Design was always a company, which cared about users a lot, adding new features and supporting products for many years. This is the reason we at my company have invested in couple BMD cameras, ATEMs, speed editors, color panel...
Blackmagic products are not the one and only on the market - my loyality came from belief, that BMD does the ultimate best job in customer care, and no matter how big my company will grow, we will always be taken care of.
I hope that this issue left unresolved for so long is just a silly mistake, someone maybe didn't notice it, and it will reach those who's job is maintaining this compatibility.
To the matter - I've just confirmed, that both lenses work well on BMPCC4K (firmware 8.1) with Metabones x0.64, however don't work on BMPCC6KPRO (firmware 8.1) - attaching Tokina 11-20mm F2.8 CF ATX-I is not recogined at all, Sigma A 18-35 displays wrong aputure values and 'jumps' back and forward while increasing iris value linearly.
This is a serious problem for those who use photo lenses without manual aputure rings and because those users are especially a target for all BMPCCxx cameras, it deserves attention.
