So I'm sitting here looking at a fuji x-e1 with the 18-55 wondering if I should break the seal. If there was an M43 lens that was moderately fast and fairly sharp under $600, this post wouldn't be here. Yes I understand that both the Panasonic 12-35 and Oly 14-40 are pro class glass and weather sealed. Something I don't need. I still shoot Nikon DSLRs and am a huge fan of the Tamron 17-50 (non VR), in fact that lens has followed me through a couple of systems. Why oh why can't there be an equivalent in the M43 world.
