Summary: I just wanted to mentioned that I'm just thrilled with this Sony lens. As some mentioned it's not professional quality nor is it made with the highest of construction materials. But so far this has exceeded my expectations.
Excerpt: A very cost effective lens and in my opinion a must have lens on a APS-C camera. My initial work with this lens simply impressed me due to its versatility in coverage and closeups. In fact it's macro capabilities are quite exceeded my expectations.
Pros: Consistent Output, Easily Interchangeable, Fast / accurate auto-focus, Lightweight, Nice Bokeh
Summary: It's really a fabulous little lens. I'm still learning how to use my camera, along with this lens. This was my first prime lens purchase and I know a real macro lens is a great thing to have so I've only just begun to scratch the surface of what I can do with it. But I'm definitely happy with it.
