Well, these 2 lenses will be in my kit as soon as they're out. I had the ZD 7-14 F/4 and wanted another stop and a smaller lens so I sold it. Now I can have that F/2.8 lens and my hope is it will be smaller. And a 300/4 was always one of the MIA lenses in the ZD lineup (who could afford the 300/2.8???). I do agree that a 1.4X for the m.Zuikos would be nice, however, I've been experimenting with the digital in-camera doubler and, while it gives only a jpg out, it is a really nice jpg which, with this lens, would be a 1200mm (35mm equiv) focal length.
