I have this lens as a supplement to my heavy, bulky 14 - gained 24 Wide Zoom. So far I used as "replacement lens" an old 20 MF 2.8. This was also light and small, but with respect to optical performance can not be compared with these Niko innovation. The new 20s is absolutely outrageous! With 1.8 maximum aperture, creativity knows no bounds. Would not physically normal for this focal length distortions occur, could you actually use more as a portrait lens, it has to. Unlike the zoom, this lens has an incredible Minimum focusing distance of 20 cm! At maximum aperture, it is already very hot, the bokeh is similar to the wide-angle zoom. In Focus range I can not see any weaknesses, in my opinion, it is the zoom least equal, but I must confess to be a pixel counter. The 14 - 24er pumped much air when zooming, a great advantage of Fixbrennweite is that longer without zoom function of the sensor is kept clean. From me there is an absolute buy recommendation! PS the two sample images I took with visor 1.8.
