converter/adaptor ?

[nwyman]

Recently bought Powershot s1 at very good price from disreputable dealer, who enticed me into buying generic telephoto and wide-angle converters at a BOGO price.
The salesman told me they would fit the S1 and included an adaptor.
Camera came and I am very pleased with it - converters are another story.
When I use them at maximum zoom, I usually get a "clunk" noise, occasionally followed by an E18 message. (I think this means the zoom is hitting the converter?)

I next purchased a proper Canon teleconverter, which seems to work fine.
Am still getting the "clunk" with the wideangle off-brand converter.

When I look at various sites, I see the Canon adapter for these converters is a two-piece product, involving a hood as well as an adapter.
The adapter I got from the disreputable shop is a one-piece tube, labeled "for Canon S1".

So, my question is - should I just go ahead and buy the wide-angle converter from Canon (after saving many more pennies), or will I be able to use the off-brand converter if I spring for the official Canon adaptor/hood set?

Thanks in advance for any advice.

nwyman:

I had a quick look at some adapters on the web, is it one that looks like this?

It is possible that this converter needs another adapter ring to inset inside the adapter. I know that my old s45 needed this.

If it is one like this try giving Tom at CKC power an e-mail and describe your problem. He is very friendly and might be able to suggest an solution.

Good luck,

thanks for the advice, John.
My adapter came in box labeled "Bower", and is black metal, but looks very similar to the one pictured on the site to which you referred me.
I'll try contacting Tom.
