Bunch of M4/3 Oly Primes, time to ditch the 12-50mm?

I like it too, a little bit anyway. It is not too bad for a kit lens I think. Better anyway than the Canon kit lenses I once owned but never used. Real sharp wide open in the center at 12 mm, a little less sharper at 20 and worst at 50. But if you set your aperture to 5,6 it is reasonably sharp all the way from 12-50 also in the edges. It has a nice zoom length and it is weather sealed. So it is very practical, and IQ-wise good enough as a standard walkaround lens.
