I had it once, mounted to my Fuji S5. Great image quality in every respect, which means high sharpness and contrast, very nice bokeh. But AF via micro motor was very slow and not the most precise one. I think you will be better of with the Pentax version: from what I've seen on youtube, AF is markedly faster without the micro motor.
