These two images were shot seconds apart. The they show very well how much difference a circular polarizing filter can make in your images. The images were shot on a Sony NEX-3 at 18mm and I should have looked to the edges for the vignette but I still like the image. There are some companies which make thin filters and this would have helped so it is not a fault of the camera. Unless of course you cannot use a polarizer w/o a vignette at 18mm which may be the case with some wide angles.
