Excerpt: I use this lens for wildlife and kids sports. So far I've been very happy with it. It's fast enough for my needs, has very good image quality, and I would consider it light for its size. Not that it's a huge lens but compared to other lenses in my collection.
Pros: Consistent Output, Easily Interchangeable, Fast / accurate auto-focus, Lightweight
Summary: Tested and used this refurbished lens today in Sierra mountains. Performance was flawless. With integrated auto focus and IS on Sony a6000, this is a combination that is hard to beat, especially for total investment less than $800 for camera and lens. Yes, it sticks out.
