Monito's Filter Rules:
0) The best filter for protection is the opaque one commonly known as "lens cap".
1) Use a lens hood to protect the lens when the opaque protective filter must be removed.
2) Never use so-called 'protective' (clear) or UV filters for digital, except ...
2b) Use protective filters when photographing in the middle of a riot involving liquids (drunks, for example) or a sandstorm or a projectile fight (paintball) or close to ocean spray or other severe hazardous duty.
2b1) Some Canon L lenses only become properly weather-sealed when a filter is attached to the front. If the weather is that wet (strong stormy wind-driven rain), it counts as hazardous duty (see 2b).
2c) Clear or UV filters can only reduce colour contrast (never improve it) and sometimes introduce extra flare. These effects are almost never desirable.
2d) UV and 1A (pale straw yellow) filters have a place for film.
3) Almost always the only filters needed are Circular Polarizers and one or more Neutral Density filters.
3b) There are very expensive ($300 each, appr.) filters available that have very sharp strong cutoffs against both InfraRed (IR) and UltraViolet (UV) light. These may be useful for critical portraiture, catalog, and scientific work.
3c) The filter effects commonly used for film can almost all be easily done with White Balancing or Tint in Raw conversion or post-processing.
4) Use multi-exposure HDR techniques in preference to Gradated Neutral Density (GND) filters whenever possible which is almost always.
4b) Use the correct spelling for Gradated (derived from "grade" meaning slope or smooth change); not "Graduated" which means "marked" or "calibrated" as in a graduated cylinder for measuring liquids.
4b1) Do not fret when most people use the "graduated" term.
5) Screw round filters on slightly less than "finger tight" (nearly tight).
6) Don't bother with cumbersome filter holders for square filters unless the lens has no screw on filter mount.
7) Buy the best quality filters that can be afforded: B+W, Heliopan, top of the line super-multicoated Hoyas. Avoid Tiffen (gel sandwiched in two glass pieces), Canon, low-cost Hoyas, etc. Nikons are mid-range. Marumi filters are a new line and are developing a good reputation for value.
I've never had a stuck filter that I could not remove with ordinary means (no hacksaws or glass-breaking).
By the way, the recommendations to apply a bit of oil or grease are good and I may start using them. A bit of oil wiped from the top surface of the nose should work when better lubricants are not available.
