Bought this for Sony Nex 5 camera. CPL works and managed to reduce reflections on shots and change saturation for shots of sky etc.
Wouldn't bother with the UV as a protective filter unless you plan on throwing your lenses around. Suffers from some problems with light sources, not sure of the technical explanation whether its refraction between filter and lense. See the customer image I've put up of a cava bottle in a cooler. You can see the blue light on the front of the cooler is somehow being shown the bottle when the UV filter or CPL is attached. Cheap and cheerful, might invest in higher quality ones when my photography is a bit more advanced. Plus with modern cameras auto white balance and choices of white balance options means FL filter is pretty much useless and the UV doesn't really do much other than being a protective filter. Would recommend instead investing more in a single CPL or UV filter.
