The polarizing filter is a very useful accessory for photography and filming in the summer because it eliminates the blue cast and draws the sky in a bright blue. But also for shooting reflective objects such as showcase, car windows or water surfaces the part is simply indispensable. One sees oneself without mirroring what's behind the showcase and recognize clearly the fish underwater. A loss of sharpness, I could not tell. This is then securely to the camera. The filter can, however, be described as fair-weather filter, since he takes away quite a bit of light (in summer or snow may even be an advantage "neutral density filter"), he can not as a UV or Skylight or 486 IR-UV cut filter always remain on the lens. For filming the version is much more practical without nipples, as you the Polarizer anyway can not rotate during filming, without that one would either engage in the image or shake the camera. Especially with film cameras, where you always complained that the colors are not strong enough, this filter provides effective help and you do not want to miss.
