10 out of 10 points and recommendedSuper sharp, Versatile and weather proof.Slow sometimes difficult to focus.
I really like this lens. It is crispy sharp even with the macro tube, and at all apertures. The color cast is neutral and it can be used for almost anything where a 100mm EFL slow focus prime lens is an appropriate choice.reviewed December 22nd, 2008 (purchased for $500)
However the focus is slow and sometimes imprecise. Often you have to "feather" the shutter to get a clean focus and sometimes it misses the focus point completely.
However, if you invest enough time to get to know this lens, it will produce the best pictures that a given 4/3 camera can produce.
