I used to look down my nose at these "close-up filters" and "accessory lenses" until I got John Shaw's excellent book "Close-Ups on Nature" and then doing more research. There are some superb optical achromat lenses that you can get, but they are not the cheap-O +1, +2, +3 close-up filters you are probably thinking of.
See "SUPPLEMENTARY CLOSE-UP LENSES (FILTERS)" on this page to get you started: http://jimdoty.com/Tips/Closeup/closeup.html They offer some serious convenience advantages when used on AF zooms.
