Use of a filter I have just purchased the Panasonic FZ28 and noticed that Amazon recommends buying this filter. I am a novice and will be learning as I go along. What is the purpose of the filter? Is it necessary or just something nice to have? Thank you for your help.
UV protection filters became popular with film cameras, UV light could throw the colors off on film, so having a UV filter became a given. UV filters are not needed on digital cameras, however it was found that often the filter would protect the lens from damage, so people still use protection filters on their lenses. I use protection filters, but, choose Hoya DMC PRO1 Clear Protector Digital Filter. The Hoya PRO1 filters cost about 1/10 the cost of the lenses I protect. They are DMC which stands for digital multi coated, which means they have the same coatings as the lens to protect against lens flare and ghosting. They are also optically better than cheaper filters so they wont distort your photographs. They are not UV filters because digital cameras don't need a UV filter.
The Hoya 52mm DMC PRO1 Clear Protector Digital Filter is the same size as the Tiffen 52mm UV Protection Filter. Yes it costs 7 times as much as the Tiffen, but, do you really want all your images going through a $5 filter before going into your $400 camera?
