My next lens purchase will be one of the macros. Not till October though, and in the meantime, I would like to try some alternatives. Yesterday, I almost purchased set of 12,20,36 Kenko tubes, but I've also come across Raynox DCR 250 and seen some excellent results, but most samples did not specify which lens was it used with. Since it fits 52-67mm filter size, and my only lens under 67 is the good old 18-55, I would like to see some results with this set and with other lenses as well or hear your opinion. Or maybe I should skip the Raynox and just get mentioned Kenko set? What will give better results with 18-55 (or any other non macro lens), and also, what will give better results with macro lens, Kenko set or Raynox 250? I would be most grateful for any input.
