I'm dog sitting...and trying my new 75mm 1.8

I got the 75mm the other day, and haven't had time to try it much. Today I tried to get some shots of my son's girlfriend's dog. He never held still, but I was still able to get a few shots off. Taken in my living room with only window light. These are jpeg's from camera with slight levels adjustment, nothing else done. I'm really happy with this lens (the E-M5, too). Thought I was shooing at f/1.8, but I guess not.

f/2.5, ISO 1600, 1/160sec.

f/2, ISO 1250, 1/160 sec.

f/2.5, ISO 1600, 1/100 sec.
