I recently started digiscoping with my Panasonic Lumix G1, the kit lens, and my Swarovski ST80 HD scope, using the Swarovski digital camera adapter and Swarovski 30xW eyepiece. There is some vignetting up to about 16mm and beyond 21mm or so, otherwise the combination works well. A sample is attached, shot at 18mm, f/4, 1/15 sec., ISO 400. I would guess the effective focal length is about 1000mm. I've ordered the 20mm 1.7 pancake lens which should be about ideal for this setup.
