In my opinion, the best standard zoom at all and thus actually the case for μft. Whether close-up, landscape or portrait, the quality of images is absolutely perfect even at maximum aperture. Of course, up in the corners and on the edges. Trailers other systems this lens has been up to the despair that they started as clowns div. Board to claim that the objective but is not f2.8 niggly :-)) Of course you have a different effect in the depth of focus, but the aperture is clearly defined and I want to mention only the margin. Haptic it fits perfectly with the E-M1. Switching to manual focus I find very convenient, the function key is an added bonus this Objetkivs. All other positively highlighted features of this lens in the product description I can absolutely confirm. For the performance offered, the price is fully in order. Cheaper us customers would certainly always prefer :-)
