I took for nex 6 in addition to the whale 16-50, to work in the conv. low light and portrait photography. In my opinion, these tasks are quite fulfills.

Working at small apertures is complicated by the complexity of focusing - I almost missed everything in soap (depth of field from a distance of 5-10 centimeters)
