Not bad for a kit lens!
After 24 years shooting Canon, I sold my 6D body and seven lenses over last summer and bought an X-Pro 1, an X-T20, and several lenses. I kept my two Olympus EM5 bodies (for which I couldn't get much anyway) and three lenses. I have read many statements on the internet to the effect that any difference in image quality between Fuji and micro 4/3s is only marginal, but I will state unequivocally that I see the Fuji image quality as a LOT better. In fact, the files, even from the 16- megapixel X-Pro 1 are every bit as good as those from the 20 megapixel Canon 6D. Files from the X-T20 are even better.
