It appears that the standard Gary Fong Flip-Cage will not fit the Pen models or the GF1, judging by the compatible camera dimensions that are listed. They also make a Flip-Cage Pro that supposedly fits larger cameras, but the camera dimensions that are listed on the Gary Fong site are the same for both models. Does anyone have Flip-Cage Pro? If you do, have you tried it with a Pen or GF1? More to the point, if you do own one and have tried it, does it actually fit and work ok? I have a little table-top tripod from Kodak, and while it carries small and works well enough (stability wise), it's a bit of a nuisance to attach to a camera, like all micro tripods I've tried that use a screw attachment. And while it's small, it's still too large to leave attached to the camera all the time. The Flip-Cage seems like a pretty good idea, but it doesn't look like it will fit any of the micro four-thirds bodies.
