MZ10 with my new Pentax Ultra Wide Lens

I just recently aquired a pentax smc ultra wide lens 18-35mm fa which gives a full frame shot on my film mz10 camera. I just only taken a couple of shots with this lens but more will come, im still not convinced about the image quality of this lens only after I scanned the photos can I judge the lens.
One thing I really liked about this lens is that it can auto focus a very important feature on street photography. Focusing is pretty fast with my camera and got no problem on dark situation although sometimes it do hunts for focus. Here are some images taken with this lens and the lens photo as well.
