OK i will rephrase it... it is very well documented that the sigma lenses can be much more unreliable in the AF especially in the outer AF points than the alleged unreliable AF system on Canon DSLRs with canon lenses however its well documented that on DSLRs sigma lenses AF works much better in LV on DSLRs and on canon MILC as do canon EF lenses ..

That’s incorrect. It’s not documented that sigma lenses are less reliable than canon lenses.

The same problems were widely reported with canon lenses as well.

it dont matters what the reason is for it ..... whether its the body's fault or the lenses' fault or canon's fault or sigmas fault or whatever...

It does. If someone is saying that third party lenses are not reliable, but in fact it’s canons af that is not reliable, the blame is not on the lens.
And I know this because I shot canon for almost a decade and was using the same canon lenses on a 5DII and on a 1Dx, and they performed differently on those two bodies.

Saying that reverse engineering EF didn’t produce reliable lenses is a myth. Those lenses work perfectly with that EF protocol when used in a mirrorless camera.

That is the best part of the movie Gaslight. Now do it for the EF 50 f1.4. Make the EF 50 f1.4  AF drive reliable.
