For unknown reasons Olympus US decided NOT to offer the new Olympus 40-150mm PRO + 1.4x Teleconverter bundle savings in USA. Such a bundle is or will be available in Asia and Europe (news via Photographicwanderings.com).
Here are the PRO zoom and teleconverter preorder links:
40-150mm f/2.8 PRO lens at Amazon, Adorama, Bhphoto, GetOlympus. In Europe at Wex UK.
MC-14 1.4x teleconverter at Amazon, Adorama, Bhphoto, GetOlympus.
