Thom's Mini Review: An expensive, dedicated macro lens. I wanted to like this lens, but I kept finding that it didn't live up to my expectations in a couple of areas. Optically, it's excellent, exactly what you'd expect from a Leica-designed lens (and unlike the 25mm f/1.4). I had no problems with it in the optical arena, and it produces excellent macro results, too. The problem is focus. It's a slow-to-focus lens in my experience, and a temperamental one when used with continuous autofocus. Manual focus on the current crop of m4/3 bodies doesn't exactly excite me, and for macro work, getting precise manual focus is also high on the list of desired traits. Generally, I felt I was often fighting to get the focus point I desired with this lens, and that struggle increased the closer the focus point. So the question becomes one of price versus expected performance, and I think this current iteration fails. Perhaps with the GH3's faster autofocus I may change my opinion here, but for the current crop of m4/3 bodies I just felt this lens under delivered on its promise, especially considering its price. Excellent build quality. Not Recommended
