<p>[QUOTE="dougsmit, post: 7985970, member: 19463"]I hope you are not using both tubes. The 10mm alone is a lot on a 14mm lens but should get the whole coin at 42mm. The size tube you need is proportional to the focal length of the lens. I have never had a 4/3rds camera but I would suspect there would be a market for a shorter tube if anyone made one. If you have any longer lens (telephoto) the tubes would give more working distance and allow light to fall on the coin.[/QUOTE]</p><p><br /></p>
