Re: That "L" lens "look" - Canon v Sigma 35mm1.4

Because the AF data is proprietary and Canon does not give it away. It has to be reverse engineer by Tamron, Sigma, etc.. Every 3rd part lens I have used, and it was the best of the group, I notice always was a little slower, or not as accurate as the Canon lenses. (when compared to the L lens)

None of that is true. How is the communication between first party lenses better by far?  And how can something always be faster in most cases. Mothers are many third party lenses  that are just as fast to autofocus as first party.
