Tamron makes a variety of lenses in a Fuji X-mount, so with any of those you'd be good to go. But I assume you already knew that and are instead asking about an adapter for a Tamron lens you already own, and presumably one that has contacts so as to maintain AF functions and lens EXIF communication, right? All the known and trusted outlets (B&H, Adorama, KEH, etc), as well as Amazon, eBay, and others have adapters available for whatever mount (Canon, Nikon, etc.) your Tamron lens happens to be, but many of those don't have contacts. Metabones (generally well regarded) and a couple of other makers do, though, but they do tend to be relatively pricey.
