    I have a Oly 9-18mm, used it recently for a shot near the sea, and afterwards found that there is a bubble of water inside the lens.

    ANy advice on how I can fix this?

    Not powering on the lens. Then sending in for repair.

    If you want to try this you can place it inside a plastic bag with some new silica gel packets or dry common salt (dry it under the sun, on a heater, oven, not in microwave they say), close with a knot and wait a few days. But even if you can drain the water out of the lens some residues will probably remain around (salt, dust, etc.). So I think it will need a disassembling and cleaning anyway. It really depends on the bubble size.

    EDIT: obviously do not cover the lens with salt, place the salt in a cup

    Wow, unlucky.
    When I take my 9-18mm near the sea this does not happen...

    IN the sea would be another story.

    I would steer well clear of salt, It's quite corrosive.
    If you don't have silica gel to hand, raw rice works remarkably well, and may be a better option than the small silica gel packs most places supply anyway.
    Airing cupboards work well for the gentle heating needed for drying kit.

    A bag of rice works well for drawing out moisture out of phones and pc components, so I imagine it will work for lenses as well. I have a gallon size zip lock bag about a quarter filled with rice which I have used in the past with great success. To avoid direct contact with the rice and reduce the possibility of replacing the water bubble with dust, I would set it up with the bag draped around an upturned coffee mug on a table with the portion with rice on the table. Then you can place the lens on the mug and close the zip lock.

    Good luck in any case. I have only had the lens for a couple of months, but I really like it. Hope you can get yours sorted out.
