I am asked if I am willing to accept a 30% reduced performance. I would if it means a reduction of 30% or more in pricing.

Wow. That's quite a comment.

If I cant afford a Ferrari then I dont go around expecting a Toyota to be at par with it.

If I paid $750,000 for a Toyota, I'd expect it to perform.

Hasn't it been more than a decade since any third party lenses have been made incompatible?
And even if Canon were to try something like that again, these lenses are all designed with upgradable firmware now.

Its going to happen!!

OOPS, it just did. A whole host of Sigma lenses were incorrectly reverse engineered and have issues on the T6i. Sigma is offering to fix the ones still in production, but any older ones that won't work are just throwaways.
