I've got an E-M5 with my name on it on the slow boat from Japan. In the meantime, I've started to look at the lenses that I might need. I ordered my E-M5 w/ the kit lens and 40-150 ($150..can't beat that!). My daughter dances ballet and will also be starting karate this summer. On my Canon system, I used to use my Tamron 17-50 f/2.8 and Canon 85 f/1.8 for the indoor shots. I'm looking at the Olympus 45 f/1.8 (90mm equivalent) for this purpose. But a low light zoom, probably f/2.8 would be best for this. What would you all recommend for these types of indoor shots. Thanks!
