Anyway so i got my new camera and i have to say the quality is amazing and its so light! Anyhoo i have a question, in the accesories i got, i got a polarizer filter. Now I was reading up and they say for Auto-Focous its like a neccesity. Should I leave the filter on 24/7 or what??? Or should i only put it on while shooting under certain conditions. Thanks alot and Happy Holidays.
