X100 - Anyone using a Oly WCON-07 wide converter on it?

Hi, just wandered if anyone has tried using an Olympus WCON-07 on their X100?

This particular .7x wide angle converter seems to be of a high quality optical design, at least on paper - as it has 4 elements in 4 groups, whereas most other designs are either 2 or 3 elements.

Anyway, I have ordered a WCON-07 off Ebay and will probably only receive it in a month or so, so I am just very curious hence the question posted here. Also, I could not find any info on Google as to this specific combination.

If I do not get any response, I will report my findings here, if and when I receive my WCON-07
