TAMRON A 09. 28-75mm 1:2.8. I purchased this used and have been using it for photography. It's a user-friendly lens with a bright aperture. I'm selling it because I'm scaling back my photography activities. It does not have image stabilization. It's an older item, so please consider it as junk (no returns, no claims). F-number (wide open): F2.8 Other features: Lens hood, filter included.
