I recently purchased a used DSLR with multiple lens and wondering about the use of filters. Only used point-an-shoot till now.
I've read that "always" permanently install UV filters on all lens, and always use a circular polarized lens outdoors.

Advice I may consider? Lookinf forward to your comments and thanks in advance.

There's no such thing as 'always', but we instead use "most of the time"...:) Outside, in bright sunlight, with reflections from non-metal surfaces (e.g. water, etc) a circular polarizer will help cut glare, and allow you to darken the sky. Usually highly recommended. Not needed inside, for portraits, night, or infrared photos. Buy quality. Match your lens' front element diameter. Use SEARCH function here to see dozens of similar threads.

2) UV filters can be used as 'protection' against flying dust, grit etc outside but are not needed for UV filtration. Sensors are not film.

3) Other filters are not needed at all, as nearly all their effects can be duplicated in post production, without the attendant image quality loss that glass filters may introduce.

4) Neutral Density and Graduated Neutral Density are other types usually recommended for outdoor shooting in specific situations. SEARCH is your friend.

Thanks for the information, and I will keep the UV filter on the lens, if nothing else than to protect against accidental scratches and dust. I wonder why UV filters are recommended in DSLR ads?

To sell filters. Big markup on them. Ever had a car dealer recommend undercoating?...same concept.

Thanks, good analogy.

Currently, there is a thread directed to the use of a UV or Skylight filter on your camera.

It is good reading even though I am set in my ways and will not change. It gives you various opinions about using at least one of those filters.

Casmire, I have had good luck with ebay filters from china. I seriously doubt that any filters are now made in USA and that specifications vary a great deal. Some suggest multi coatings are only on the "expensive" name brand lenses.

Because a previous camera used 58mm and I have already invested in a wide variety of 58mm filters; I have standardized to that size. So, if a Lens is 52 mm, I use an adapter step-up ring.

Regarding most of the time and always as stated above... well if a UV or Clear filter is damaged, throw it over your left shoulder, if your good lens is damaged, shed a tear.
