I am buying the Canon 28-135 lens and am looking for a filter to protect it.
I had a friend says do not buy a UV filter as it will darken the images. I
have HOYA UV's for my other lenses. He says I should buy a
sunlight/daylight filter. Any feedback would be appreciated. Thanks.
The terms "daylight" and UV are a bit squishy. Silicon chips are less
sensitive to UV than most films, so there is not much of an effect due
to either, but one needs to know the actual spectral transmittance of
what each filter mfg means by those terms. However, for most, with a
digicam, the effect is little different than clear glass. By the way,
I am more familiar with a "skylight" filter than a sunlight or
daylight filter. Is that the one you mean?
