Most any lens will get worse past about f/8 because of diffraction, and this is only magnified with macro type photos. So I'd suggest F/8. On your presumably very steady copy stand I would use ISO 100 and a longer shutter speed for better quality. The -3.3EV, which presumably you've had to dial in to adjust the exposure, is a result of using AV and spot metering on the coin. You can do it this way, or you can meter against a gray card, shoot in Manual, and be closer to right from the get-go.[/QUOTE]</p><p><br /></p>

It is taken with: AV f/20 1/60th sec ISO 250 -3.3EV While I agree you've got three larger issues right now: 1) Lighting 2) Focus 3) Practice, you should also look at these at some point.
