Jokin, does PANOCPL come with filter and adapter? It looks ideal, if adapter screws on to camera (where?) and filter affixed magnetically can easily be pulled off for night use. A bit expensive for my taste, but then it is dependent on the quality of the filter. I'd rather do DIY on my new "G" that I got from Pier 28 if at all possible, but I don't want to buy the wrong size filters / adapters.
My dash and speaker grills / vents reflect heavily on the windshield, hoping a CPL filter will fix the problem.
