Cute captures! Although it seems that there's a bit of blurriness on your grandson's face in the first one. I'm not sure if that's an AF "miss" or from handshake.
I've got this lens to, it's on my camera 80% of the time.
35mm is a good focal distance, but it's not quite as versatile as my 20mm µ4/3rds that i own. When i first got my GF-1, that's the ONLY lens I used for 2 years!
