Title: Excellent macro lens.
Review: This is an awesome macro lens. Optically, it's amazing. And the ability to focus so close at 180mm allows you to capture some amazing macros. Or, if you prefer, you can use the focal length to shoot from a little further away and still get pretty good close ups.I haven't had the problem that a few other reviewers have had with focusing. It doesn't have its own autofocus motor, so it depends entirely on your camera's screw drive. I've used this lens on three different Sony alpha cameras (A550, A77, and A850), and have had no problems. (Perhaps the other reviewers were using very old cameras? I have no idea.)I find Tamron lenses to be amazing values generally, and this lens is no different. Highly recommended!
