It has a nice look to the bare metal that gives it a softer appearance if that's the right term. Whenever I hear it, I think of space age materials, stealth jets, and race cars. It was supposed to be the material of today!!! What happened?!
    Expense, and manufacturing difficulties. Have a look at http://en.wikipedia.org/wiki/Titanium

    What happened is Titanium is as light as Aluminium, as strong as Steel but is as expensive as Silver.

    Yes, nobody has yet discovered a way to get metals to live up to advertising hyperbole. Sad, isn't it?

    I'm vey familiar with Titanium, I used to be an engineer with a company that made some of turbine blades for Rolls Royce jet engines with it, and I still have a ring I made for myself out of it.

    I have a passing acquaintance as well, I've used it to make connecting rods in miniature engines. The strength/weight ratio allows the rod to be made lighter thus reducing vibration, there is no way to properly balance a one cylinder engine. It needs a bronze bushing to wear well, and machining requires a light cut, fairly high surface speed, and plenty of coolant.

I have heard some people have an allergy to this metal, so it may have a down side.
    It should be clarified: cameras are made of an aluminium alloy casting, many parts of various materials such as steel, brass, plastic, etc; and are covered with brass covers which are either painted (usually black) or electroplated with either chrome , nickel, "black chrome" or, if you're an aspiring pimp, gold.

    The metal you see when you look at the camera's top and bottom plates, (or a lens barrel), is an electroplated (or anodised) layer.

    I think metal camera bodies are made of magnesium alloy.

    Some of the nice things about brass.

    o easy to machine
    o does not rust or corrode
    o strong
    o dimensionally stable
    o brass on brass threads will not seize
    A rock pile ceases to be a rock pile the moment a single man contemplates it, bearing within him the image of a cathedral.

    Some undoubtedly are. Many are aluminium alloy. Some were cheaper metals/materials.
