Exceptions are environments that adversely affect the front lens. As at the beach or at sea, better salt water with a wet and then wipe with a dry cloth of the filter, as scratching the front lens or attack their coating. The same is true for drifting sand and dust.
Therefore prefer to use a tempered reflexionfsreien filter as a cheap shard that might still generate distortions or ghosting.
So my choice fell on the Hoya UV Pro1 Digital Filter 52mm.
Very well made, a quality filter. But be sure to remove the flash photography.
