I tried using my f/1.7 CCTV lens for this one. It was a real pain due to the lack of auto focus. But the focus hunting on the 14-42 Panasonic Lens was unwanted as well. I think I’m going to have to teach myself how to manual focus on the fly. Thing is the 14-42mm lens does not have a smooth focus at all. So I’m thinking I need a handle, like some sort of jar opening device that I can clamp on. Or get a better lens, which is an option.
