I normally using my Panasonic G9 with an Olympus 60mm with extension tubes or/plus Canon 500D dual element filter for the small fossil images. However with many of the fossils I am finding using my stereo AMscope (at the 3x-45x configuration (.5 reducer)) with my Panasonic Gx85 produces really good results (have to use a 1 1/4" to .96 adapter (for telescope eye pieces) to mount the camera with a T-mount plus 1 1/4" adapter)). Here is an image of the setup plus an image of a 5mm gastropod that had some interesting dark lines in the fossil. These images out of the camera are 16 MPX raw files reduced to 300 DPI here. I can use more light but was very pleased with this first attempt especially since the Gx85 is my small travel camera and not getting much use. I use the electronic shutter with a 4 second shutter delay to have no vibrations in the image.
