This is a Tamron high-magnification zoom lens for Sony A-mount. I used it with my α7Rⅳ and the genuine lens adapters LA-EA3/LA-EA5. As it's a high-magnification zoom lens, you probably won't need to change lenses, and can shoot in most situations with just this one. I'm no expert, but there's some dust, though I don't see any mold, and it's in pretty good condition. As a bonus, I'll include a Kenko Zeta protection filter. It's a somewhat old lens, but I think it's still perfectly usable. The dust seen in the filter photo was wiped off with tissue. *Price has been adjusted to include shipping.*
