    I wonder what is the difference between the Tamron Sony mount 28-75mm f/2.8 lens and the Tamron Canon or Nikon mount 28-75mm f/2.8 lens? The price difference is significant at B&H ($879 for the Sony mount and $499 for the Canon version).
    Is the Sony mount that much better than the Canon mount version or is Tamron just squeezing the inflated price because all Sony lenses are IMO overpriced...

    I think it's just supply and demand. There's a smaller pool of E-mount lenses compared to the boatloads of Canon and Nikon. The Tamron 28-75/2.8 also has very good reviews and word-of-mouth among Sony users.

    Remember... the Tamron FE 28-75mm f/2.8 is a native Sony FE mount lens. Even Sony's eye focus works natively with the lens. So they are not identical to the Canon, Nikon et al versions. Not sure about the optical formula. But there's no doubt the firmware is different. And the mount, of course.

    Does the Eye-AF work with this lens using AF-C?

    Yep, on my A7R3.

    Looks like the price of the lens has gone up to $879 from $799.
