I've been shooting mostly with my GM5 w/ 12-32 kit lens and a 35-100 for zooms. Most of my shooting focuses on our daughter (16 month old), indoors, maybe a visit to the park or zoo, or some sightseeing in a city in that order, eventually leading to some nice portraits of the little one when she decides to stand in one spot (fat chance). I think I am ready to move to the next step and start using primes. Here are my choices PL15 O17 Sigma 19 PL25 (Maybe the new P25/1.7?) Panasonic 42.5/1.7 I would like to have a set of 2 at most, could pull off 3 if required. I am also thinking if switching to a GX7 will open up the Oly lenses for IS?
