The best features of this lens are the silky smooth focus and (clickless) aperture rings. Don’t expect clinical sharpness from this lens. This lens is all about character, from the wild out of focus areas to the wonderfully over the top and unique lens flare. The compact size means this lens often finds it’s place on the GH5 for night time walks in the city.
Although the lens sharpens up nicely by 2.8, don’t expect edge to edge sharpness at any aperture (there is some severe field curvature).
