The 2 things that make me miss my Olympus MFT experience were the 75/1.8 and the revolutionary 5-axis IBIS. While I am (for now) fully a Fuji X user, I'm still hoping to someday again pick up an OM-D as my second body. Judging by the MFT charts that are up on the Olympus website, this new standard zoom lens is truly deserving of its PRO designation. Heck, it's even sharper than the 75/1.8 and it's a zoom. And from what I can tell, this looks to be an all internal zoom. Can anyone confirm that? My mouth is now watering at the prospect of how good the 40-150/2.8 will be. Hope they continue with this PRO lens lineup --- would love to see a lineup of 1.4 (or 1.2 primes) that are even sharper than their existing primes.
