    Um whats the difference between these and UV filters?

    As not sure whether to get a UV filter for my brand new Sony A3000 or a Circular Polarising filter or does a Circular Polarising filter do both?

    Thanks

    Circular polariser will polarise and will also cut more light than a uv filter.

    so what would protect the lens more from cracking or being damaged from the sun etc?

    A bag.

    For a serious answer, a UV filter is probably what you want. They're designed to block UV and protect the front element (and since your digital camera doesn't actually care too much about UV, it's mostly the latter).

    Probably the lens cap.
    Some people put on a uv filter for "protection".
    Circular polariser might cut too much light to leave on all the time... depending on what and how you shoot.

    Polarisers are used mostly for removing reflections but it can also enhance them.
    it can do either way depending how you turn the polarizer.

    Like a car photographed with a polariser you will see more through the car windows.

    UV filters are only needed if you have crap flying at your lens. CP filters are good for cutting glare/reflections. If you had to pick one, pick the CP filter and only use it when necessary.

    UV filters are kind of a waste of money. You're better off sticking a hood on your lens than relying on a flimsy bit of cheap glass to protect your lens.
