Tamron 70-200 2.8 for Sony S mount. It's an overall great lents, it has small dust specs inside but never affected my images. You can hear the gears moving inside I don't know if this is just my copy or all of them do this. Vary clean glass no fungus or scratches. I'm selling because I moved to E mount, if you have any question please feel free to ask. I personally used it to shoot weddings pair with a Sony a77 fantastic combo.
