Up for sale: LVF1 IS SOLD. HELIOS MULTIFINDER STILL AVAILABLE—SEE BELOW 1. Panasonic DMW-LVF1: in excellent condition. Used only a few times. Complete with box, case, manuals, everything that came with it when I bought it new six months ago. $85 shipped CONUSSOLD 2. Helios Multi-finder MK2: This fits in the hot shoe of any camera. It has lines for (35mm equiv) 35mm, 85 and 135. The entire field of view is wider than 35 and works well with a m4/3 14mm lens. The 35 works well for the Pana 20mm, and would surely work well for the Oly 17. The 85 works well with the Oly 45mm. And using a kit zoom, you get an idea of the wide and long ends. It's very versatile. It's an approximation, obviously, as it is an optical sight viewfinder. Looks great on the camera, too. In excellent condition, only used a few times. $35 shipped CONUS Helios on a GF1 (not mine, but a photo hosted on flickr). Notice they're using it with the 14mm lens.
