I bought this polarizing filter to my Canon PowerShot SX 10 IS. Contrary to many reports, the different verlautenden Hama polarizing filter can indeed screw on the lens of the Canon camera. Although the camera has no real objective thread, the filter is nevertheless securely and firmly. The polarizing filter is made in the known Hama quality and can be operated smoothly. The filtering does very well noticeable and can thus effectively eliminate the disturbing light reflections from glass and water surfaces. Windows and car windows are thereby formally invisible and water gets either a color-rich surface, or is transparent so that you can see in shallow, clear waters well up to the bottom. The color of an image can be displayed by vigorous use of the polarizing filter, because you can be hide the disturbing light reflections. All this at a very good price, what more could you want. I am pleased with my purchase.
