As aprice for a single filter these would be cheap. For 3 filters they are VERY cheap and, unfortunately, you get what you pay for. I have not used the fluorescent filter as I don't have a use for it on a digital camera. The polariser is a waste of time as every image I have tried to take with it is blurred - and this is NOT due to camera shake. I know not all cameras suit circular polarisers but mine works well with my Cokin circular polariser. So that leaves the UV filter - this was the reason I bought the product -protection for my expensive lens. This works well without any noticable deterioration in image as far as I can see. If you need a polariser forget it, you are going to have to pay out a lot more money, but if you want cheap protection for your lens it is a good buy.
