I seriously doubt you will ever get even close the quality of a 2000dpi scan of a full size super sharp 8x10 document/print with a camera and lens. It all depends on the dpi you use. For example at 2000 dpi, you get approx 4 MPixel per square inch, and using 8x10 print, that would yeild a 320 MEGAPIXEL image. Youll never get close to that with any current digital slrs even if you had a perfect lens. I have two epson scanners, one does 2400 dpi, and one does 3200dpi so at 2000dpi they are not even being pushed to their limits. Even if you only use 1200dpi nearly all scanners are capable, your still talking 115 MP image of an 8x10 with a scanner. The other factor to consider is when scanning photos or documents, they do not have nearly as great a dynamic range as film does, so getting a scanner to handle the dynamic range of the photo or document without clipping is not very difficult to do.

I have been using it for several days now making copies of old (50 years plus for some) 8x10 B&W and Color prints for which the negs are long gone. I am very pleased with the quality and convenience. The quality is several stages better than what my old Canon 660U provided, and I thought it was a great scanner. But 8 years of technology go a long way! I have also copied old prints using my K20, as Ken did. The results were quick and painless, and the resulting images are as good as with the Epson. It would totally depend on the situation at hand. If I didn't have a scanner I seriously doubt that I would buy one if I seldom needed or wanted one, especially when I knew that the dslr would do just as well.
