I bought an Olympus Zuiko Digital 8mm fisheye lens (arrived 2 days ago) for the E-510. Just playing about.
All images taken at 1600ASA, 8mm, f/3.5, all exposures over 1 minute. First one looking south (Sydney skyglow on the left), the second one looking straight into the Sydney skyglow with Scorpius rising, and the last one looking north with the glow from Oberon.
