I heard a lot about this lens from quite a few prefessional photographers stating it was the best lens in the Fujifilm arsenal. Since all of them couldn't be wrong, I had to purchase one because it gives a 52mm which I prefer over a true 35mm. My opinion, a very nice lens and all those other photographers weren't wrong. Very sharp, very nice rendition and balanced very nicely on the X-T1. I find the new m43 cameras tend to focus faster but that doesn't really bother me too much. The files are excellent and the X-T1 metering is simply superb. In the image above I was certain I was going to get some blown-out whites, but ina ctual fact there were none at all.
