So the Gx85 is my light travel camera when I fly. That is not going to happen this year. So I normally use my Oly 60 with tubes or Canon 500D dual element lens for taking fossil images. But I am looking at a lot of Eocene marine fossils and many are very small (less than 10mm). Here is an image of my setup and a image of a small gastropod (5mm snail) showing interesting cracks that have filled in with some kind of organic sediment I think. This is "first light" and turns out I am quite happy with the setup.
