I had planned on setting this up after my vacation where we were going to visit Luray Caverns in Virginia but ran into a small snag. I reached into my trunk and pulled our my GX1 and realized I had left the battery in the charger back at the cabin an hour away. Luckily I had my emergency camera, my LX5, with me so all was not lost but I had really hoped to shoot the cave with my GX1 and the 14mm. I debated about showing these as they are not m43 but, what the heck. I highly recommend Luray as one of the best commercial caves anywhere - they have more formations per square inch than any cave I have been in (and I have been in dozens of commercial caves and dozens more wild caves). All shots were "natural" light :tongue: - no flash. Notice the 4' railing in the lower left corner to get an idea of the size of some of the rooms.
