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.

Personally I only buy a filter if I need to filter something. A lens
shade is likely a better idea for all but places with stuff like blowing
sand. However frankly any of those filters are not likely to cause you any
problems. Most of the issues are all so slight that very few people will
ever be able to see them. Also I have been in photography for almost 50
years and I have never heard of a sunlight/daylight filter.

Don't worry be happy.

That's a bit more topic than can be handled in a single
post to Usenet.

http://dpfwiw.com/filters.htm
http://www.bythom.com/filters.htm

The first one is probably the best, as it is aimed
directly at filters for digital cameras, while Thom
Hogan is still talking about filters used with film.
There are some very distinct differences, but perhaps
reading it with the intent of learning those differences
is worth doing, just so that in the future you can
distinguish between the two when random friends or
Usenet trolls give you short snippets of worthless
advice... ;-)

I have heard of a clear glass "filter" that is just a lense protector.
Try Adorama.

I have UV filters on all my lenses except the longest where I keep a
circular polarizing filter. If your camera has auto exposure any
"darkening" due to the filter will be compensated for.

Just remember that the more layers of glass you have on the front of
your camera the more likely you are to have flare and glare.

good things and evil people doing evil things. But for good
people to do evil things, that takes religion.

You should place the filter on something white, like a sheet of paper. A B&W
UV filter will show pale yellow. A 1A skylight intended for colour
photography or digital will show pale pink. I don't know if they have
developed something different in the meanwhile (since I had a SLR...).

Then which would be better a skylight 1A or a UV. When looking at a printed image will you really see any difference?

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?
