Macro ring light test
Another macro ring light test, this time with the Nikkor 18-55 VR and +17 diopter, handheld. Used aperture priority to f/9 to try to keep the whole coin within the in-focus range. This is the actual picture, not a crop.
What I really need right now is a reliable specimen stand that will quickly let me verify that the specimen is exactly perpendicular. The "helping hand" soldering stand that I use is handy as hell, but there's no way to position items with any kind of precision.
