I've been having a bit of a clean up and I came across this close up lens. Its hardly been used. You screw this lens onto the front of any lens to turn it into a macro lens. Its provides very good quality images for a low price. This is a high quality (made in Japan) double element, multicoated lens, not a cheapie like the 2x, 4x lenses on ebay. When you can find them new they sell for around $150 or more. I believe this close up lens is recommended for lenses in the 28 to 150mm range.
Not just for Canon lenses, will work on any lens with a 58mm filter thread (or a step up/down ring).
This lens also works on the Canon G series compact cameras (G1, G5 etc.).
Have a google around the place and there are many great images taken with this accessory.
Asking $80 postage included.
The lens comes in its original canon plastic case and is like new.
