Since the lens extends from the body, I'm guesing that you will need one of the adapters that allows fitting of addtional lenses.
I have a CP 5000 and the part number is UR-E5, this gives a 46mm thread. The one for the 5700 is UR-E8, but I'm not sure of the thread size. It will almost certainly be a standard one that filters are available for, at least with a step-up/down ring.
You can buy individual filters in any branch of Jessops and they will also have adapter rings should you need to step-up/down the thread size. |
