[QUOTE="kanga, post: 1335342, member: 9270"]I had trouble with the whole coin NOT being in focus (okay in the center but losing sharpness out toward the rim). I had two problems contributing to that, both as a result of the camera being too close to the coin: 1. Depth of field - I stopped down the aperature but to compensate I had to lengthen the exposure time. That helped some. 2. I moved the camera further away from the coin. That improved the geometry of the exposure. The two adjustments corrected my problem.[/QUOTE]
