You mean less than 38mm...you can add a wide angle converter, the best being the Raynox DCR-6600Pro (I have a C-700 with this lens). This lens actually has a negative barrel distortion which corrects the existing barrel distortion of the C-7xx lens.
You can see the various lens options (including a 2.2x teleconverter) for the C-7xx cameras here:

Some of the Raynox lenses aren't cheap, but they are GOOD QUALITY!!! You can get cheaper ones through Ebay, but they are usually garbage (especially anything labelled "Titanium").
Also there are some from Olympus, but many C-7xx users prefer the Raynox lenses (especially the DCR-6600Pro for reasons I already mentioned).
