Following one or two fairly lengthy discussions on other threads on this forum I approached Fuji on the issue of add-on lenses and received the following response from them:
The FinePix S9000 digital camera can use 58mm filters available from professional photo supply retailers. Unfortunately, you cannot attach adapter rings, telephoto lenses or wide-angle lenses to the S9000 lens. We are unaware of what Raynox has been producing for this unit and do not recommend using them until we have run tests.
We sincerely hope this information has been beneficial to you. If you should have any further questions or concerns, please do not hesitate to contact us again. It would be our pleasure to assist you.
Thank you for your interest in Fujifilm digital imaging products and services
Personally, I think this fact should be spelt out in the 9000/9500 Owner's Manual! But then again, I think they are marketing a camera that never needs a lens change(one-upmanship on the DSLR!).
