I bought a
58mm GPE Circular Polarizer from DealExtreme. I wanted to use it with my current CPL to try and make a variable Neutral Density (ND) filter. You may notice that the picture here doesn't match the one on the website. The brand name is different. It looks like I ordered a Massa but got a GPL. I'm not going to quibble about an $8 filter with DX, I'll just assume that they are equivalent. Build quality is fair. My lens cap doesn't fit as solid on the GPL filter as it does on my more expensive Hoya. I haven't done any side-by-side photo comparisons between the two filters, but through the viewfinder they appear to perform the same with no visible colour cast. At least when used alone there is no colour cast. When the two filters are mounted on the lens to fake out a ND filter the colours tint from blue to orange. There is drop of about 3 stops but it's an awkward combo to use. It will be nice to have the extra CPL kicking around so I don't have to swap it around every time I want to change lenses, but I think I'll invest some money in a real ND filter.
