First stab at macro using tubes and an older nikon 35-80mm zoom. I had purchased raw amber rocks that I broke up and polished and found some insects inside.

Nicely prepared and shot.

If I recall correctly, amber has the same refractive index as glass, or thereabouts.

Not sure but it was tough to get good focus. Just using an small led flashlight to illuminate. Most of the other shots were too back lit. But I was just seeing what kind of results I could get with the tubes. They are a cheapo set and I had no aperture control. I think it just read F_ _ . I will try again with a different lens and work on the lighting for the other amber fossils.

Thanks for the feed back.

Your amount of extension/magnification will give you effective aperture control. I am currently experimenting with a 4/3 lens on full frame, using manual tubes. The diaphragm remains fully open but use of tubes and/or TC increase magnification and decrease effective aperture and increase DOF in proportion.
