Since this lens is commercially available, I have read a lot about it in the camera forums, which has also helped me in deciding. I wanted a immerdrauf lens for my Fuji X-E2. This wish I fulfilled with this lens. It is small, light, fast AF and in "Rattenscharf". Traut you this "pancakes" really not. The only thing that is perhaps disturbing, is the loud focus in quiet situations. The camera fits with this lens in a small waist bag and can take it everywhere. Unfortunately, there is no lens hood to, this one has to get himself, but this is not so simple. We must find a suitable first. The front cover is to be enjoyed with caution, the purchase and take them from this time can quickly snap out of his hand. Is just too small to be able Zufassen properly. What we must not forget, there is also no aperture ring. The aperture can be adjusted as in the XC lenses on the camera control dial. But you get used to it quickly. About these small imperfections can look over it, because the really good picture quality makes up for it a. I can put this lens to anyone fond. The image quality is outstanding even at maximum aperture.
