I haven't used the 250D or 500D. I have used a Sony M3358. As far as I know those are the only high quality achromatic close-up filters, and they each produce a different level of magnification. The 500D is 2 diopters, the Sony M3358 is 3 diopters, but only 58mm, and the 250D is 4 diopters. Like extension tubes, they can be stacked to increase magnification. ie: If you had both, you could get 2, 4, or 6 diopters (the more the higher the magnification). Unlike extension tubes, closeup filters increase magnification more the longer the focal length, so you'd want to use these on longer lenses.
Currently the only long lens I have is mediocre quality, so I can't tell what sort of image quality degredation the M3358 gives me.
