Have you ever gone on an insulator collecting trip, and could tell what CD you're seeing, but can't tell the embossing? Too many times it's happened to me! Unsatisfied with the 12x power of my digital camera/binoculars, I searched the ePlace for SLR camera lenses and found exactly what I wanted! a 500mm telephoto lens to fit my Minolta Maxxum 600si film SLR. Contrasted above is my original 28-300mm lens fully extended vs. the new 500mm lens. Retail is normally ~$200 for this size lens, factory new; item cost, shipping and insurance: $35.50. If we could only find insulator deals like this! :-D
