Okay, I think I've figured out what the 1 - 5X on the macro lens actually represent in magnifications, but I could be wrong. I took a picture of one of the samples that had an obvious object (a lump of white, organic material) in it. I placed the white object as close to the center as I could using the grid on the viewfinder and took a "gross" image. Then I switched to the macro and took a 1X - 5X series of images placing the organic material at the center. Then I looked at each of the images in GIMP and measured the length of the white object in pixels and calculated the magnitude of the change in pixels as the magnification. I hope that's right. If you go to the "Photography" page you can see all of the images with a spiffy red border around the edge to show the actual coverage of 1X-5X.
Clear Skies,
