This is either a Vivitar T4 or TX series lens. T4 and TX lenses are interesting because they were designed to be mount-agnostic; that is, they have interchangeable mount adapters, so you could move your lens to bodies with different mounts, just by getting the appropriate Vivitar T4/TX adapter.
As Gabe Krause's answer indicates, this particular lens has the Miranda mount adapter on it. You can get a Miranda lens to Sony E mount adapter pretty inexpensively.
Alternately, especially if you already have adapters to mount other lenses to your Sony E mount body, search sites such as eBay for Vivitar T4 (or TX) mount to (whatever adapter you already have). You can "convert" your Vivitar lens to that mount, so it will use the 3rd party Sony E mount adapter you have, meaning you will need to carry one less adapter with you.
