"This objective is in a league of its own. Very well build, with weather sealing, a bit heavy due to the metal construction but nothing to worry about if you carry it all day with a K-1 or K-1 II. The focusing motor is fast and accurate, manual focusing is a pleasure, but the focus throw is a bit short in my hones opinion. From a optical point of view, this one of the best 20 something mm lens I ever used (and I used many in that range), shooting normally between f/5. 6 and f/8 getting very good results, mostly landscapes. But then it surprises too when used for short distance subjects, it renders them sharp and wide open it a pleasant bokeh is shown, keeping in mind that this is a ultra wide angle lens it a nice feature. This is what I can share after four months of use."
"Ein sehr leichtes und kompaktes Objektiv. Die Verarbeitung ist sehr hochwertig und die Abbildung sehr scharf. Ich benutze ihm immer öfter anstatt meines 15-30mm f/2. 8 Weitwinkel-Zooms. Der Preis ist zwar hoch, aber schon gerecht. (finde ich)"
