Canon 500D close-up lens (72mm) brand_Kenko What we can say forThe Canon 500D lens is a high quality doublet lens designed to work with lenses between 70mm and 300mm focal length. Because this is a thread on diopter, you can use it on any brand of lens with a 72mm filter diameter not just Canon. Optics are in excellent condition; the outer rim of the filter has a small dent which may affect the ability to mount other filters to the front of this one, but does not otherwise cause any issues. Includes case.
