I´m thinking about buying a close up lens just for the fun of it. Should be of decent quality nonetheless, though I do not expect wonders from these kind of things. Has anyone made experience with the Hoya/Kenko +3 achromats or Marumi +3 achromats or was able to compare them? Are there other brands I should put into consideration? I´m looking for a 2-lens achromat since the single close up lenses are not really good from what I´ve read.
