Rokinon 35mm F1.8 Auto Focus Compact Full Frame Wide Angle Lens for Sony E Mount on Amazon for $263

Have been watching this lens in the past few months. I hovered around $329 and today, it lowers to $263.

I plan to use this on my A6500. I read that it will become 50mm on my camera. I know it is cheaper just to buy 50mm APS-C E-mount lens but I plan to upgrade to an Alpha 7R III or newer in a year or two and be future proof.
This seems to be a good price.
