No, the 40-150 is not a power zoom, it has a manually controlled zoom. That said you could add a follow focus gear to the zoom ring and use one of Kim’s Servo Zoom controllers to get a power zoom, but it will not be via Lanc. This lens was designed for sports and wildlife photography.
The only Oly power zooms are the Olympus M. Zuiko Digital ED 12-50mm f/3.5-6.3 EZ, and the 14-42 EZ pancake Zoom. All of Oly’s power zoom lenses have the “EZ” in their name. Panny uses PZ designation for their lower zooms.
That said, all of these are still camera zooms, and will not hold focus (parfocal) very well, if at all during a zoom change. The only MFT zooms I have seen that are parfocal are the Oly Four Thirds 14-35 f/2.0 Zoom (which requires a MFT adapter), an excellent lens with real manual focus option, focus is controlled by Lanc in auto focus mode.
The other is the new Panny Lecia 12-60 Zoom, a very nice lens, setup for still and videomwork, it also is parfocal, has very quiet focus and Iris control motors, Iris is cine style smooth changes, no stepping between f/stop EV values, and auto focus is very fast, even on BM cameras, I tested it on the Micro Studio Camera.
If you need a true, remote controlled Servo Zoom with a long reach, you need to use the new Broadcast camera with a B4 Servo Zoom lens. You can adapt one to the Studio Camera, but this is going to cost almost as much as the Broadcast Camera. You will need an optically corrected B4/MFT adapter (MTF and AbelCine make one, costmis around $1500, a power adapter cable and controller for the zoom/Iris (another $1500).
