Accessories (which ones)

Hello,

I'm looking to add accessories to my Pro90IS but i can't find any article about that, neither test.

Is anybody experienced any of these accessories :

WC-DC58 ?
TD-DC58 ?
500D ?
250D ? Really don't work with Pro90IS ?

And which others brand and models are compatible with the Pro90IS ?

Thanks for any help.

500D works well. The 250D will work, but you will be working at a very high magnification (lens will focus from 250mm away down to xxx). The 250D is good for very small subjects.
