Thanks for the replies, everyone. Keep them coming. :P
Right now, for lenses I'm looking at a Nikon 5T/6T or a Canon 250d/500d. Both are two element achromatic close up lenses. I believe Schneider also makes lenses of the same design but they're even more expensive than the Canon or Nikon.
If I actually get this idea to materialize I'll try to keep this thread updated.
