Manufacturer description: Canon Close-Up Lens 500D is a double-element accessory that attaches to front of lens. It changes closest focusing distance from infinity to 500mm (approx. 19.7" from front of lens).

Of all the others we've used over the years, this close-up lens set from UK-based SRB Photographic are what we recommend here at EOS HQ if you can't obtain (or stretch to) the Canon 250D or 500D close-up lenses.

當使用 500D 時，由於會有放大的效果，所以建議快門速度不可太慢，或是使用腳架拍攝， 而依 close-up 鏡片本身的特性，無限遠的對焦會無法合焦， 如果想要無限遠也能對焦，那該使用的是增距鏡，而不是 close-up 鏡片了。

The 500D is a small double-element lens that threads onto the filter threads on a standard (non-macro) lens. It allows that lens to be focused at a much closer distance- resulting in a higher magnification of the subject.
