When I start using SLRs back in the late 60s, someone told me to get a UV filter or a Skylight filter for my lenses. They weren't going to affect the quality of the photo as much as they would prevent the expensive lenses from scratching. "Scratch the filter," they all said, "not the lens." I've been using them ever since, with an occasional colored filter when I was shooting black and whites, to polarizers and the rare usage of neutral density filter. My lenses have stayed scratch free.
As to a direct answer to your question, I'm sure some 'geek' somewhere has tested the filter vs. the non filter image. I personally doubt that using a UV or skylight filter would have an effect that the naked eye could determine.

I have a question to you since you have been using the filters since the late 60's have you scratched any of your filters and if so about how many? Do you use a lens hood too?
When I first took up photography seriously I always had a filter in place. I never scratched a filter but I always shoot with a lens hood. I have high dollar lenses but have never scratched a lens or filter. Ken Rockwell says to ditch the lens hood and always use a high quality filter to protect the glass.

If that quote is correct, then Ken isn’t (correct) in this case. Not only does the hood protect the lens, but its primary purpose is to prevent flare. Except when shooting Macro, I always have a hood on my lenses - why would you not?

Guarantee it is a quote from Ken. He states get rid of the hood and get a good UV filter when reviewing the Nikon 28-300 mm lens. I agree with you TriX, it prevents flare and protects the lens.

I don't about Stoshik, but I have filters from 1975. Except for a very cheap red filter, they are all in very good shape with no scratches. But then I use a lens hood all the time, so that is not a surprise to me. Except for the red filter (one of the first filters I bought), all of them were mid cost or better. My profesional photographer teacher told me not to skimp on quality. On the polarizer I didn't skimp but on the red filter I did. Even though that red filter was bought back in 1975, I still consider it as one of the worst decisions I have ever made in photography. It was a very cheap single coated filter. It never seemed to stay clean and then some of the coating started coming off. The polarizer that I bought at the same time, multi-coated and expensive at the time, is in excellent condition and is used on my 90 f2 macro today.

I know the testing may show marginal reasoning for buying an expensive filter, but my experience has taught me there is no real substitute for quality. And, unfortunately, in the camera market, quality usually means cost.

And as far as Ken Rockwell's suggestion, I guess he has money to burn. Or the lens and filter manufactures want him to promote such an action to sell more.

To all those who say a lens hood is for lens protection,
and not to use a protective filter:

How does a lens hood protect from dust, dirt, liquid splatter,
salt spray, or anything else? The only thing I can think of is
protection from something that is bigger than the front (eg.
your hand, brushing up against things) of the hood making
contact with the front of the lens (if it is a deep-enough filter
as on a telephoto lens).

..... a lens hood is to eliminate/reduce flare.

In my fifty plus years of photography, I have replaced two UV filters. In both cases the filter was a lot cheaper than the lens would have been. I do generally remove them when shooting indoors or in very genial conditions, but it's a pretty cheap insurance policy obtained at the cost of some possible aberration and flare. I almost always shoot with a lens hood on every lens though.

Personal choice, but I got the UV habit early, and the first time I needed it, the lens saved was a fast 200 mm Super Takumar that I could not have afforded to replace. YMMV, as with anything. I do think Ken Rockwell is crazy to avoid lens hoods. Yes, they're overpriced, but there are so many times you need one. Seems a foolish savings to me.

I use that lens. Ken is quite correct. The rest of you
clearly know nothing about it.

The hood comes with the lens, and it is rather bulky.
And acoarst a lens hood for a 10X wide-to-tele must
always be 99% decorative, or a codpiece. So, hoping
to ditch the hood, I ran verrrry complete tests, and I
found it nearly impossible to create any ghosts, flare,
or veiling that the hood has any effect upon. The lens
is nearly immune to those problems anywho.

BTW, the my test results are WITH filter in place.

This is quite true, although I wouldn't go as far as 99%. However I don't generally use long zooms, and when the quote was initially presented, the lens was not mentioned.

But even a hood sized for the shortest setting on a high zoom ratio lens serves some purpose. I wouldn't throw it out, but just recognize that it's not of much use in many situations.

Assuming your statement as to its lack of usefulness in reducing potential flare is correct (which I doubt), how about the loss of potential protection? Maybe a little “bulky” (most hoods are), but you’ll appreciate it if you drop the lens or hit it on a sharp object. But hey, it’s your lenses, do as you please - I’ll keep using those bulky hoods.

I do studio shoots for youth sports clubs where on occasion a team will be wearing "glow" shirts, which have a neon glow. I use mono lights and I use UV sheets attached to the umbrellas. I understand that the glow shirts have a chemical in them that glow when in contact to UV light. The UV filters work to some small degree, but I still get the blown out hot spots no matter what the light outputs are or the aperture settings! I have tried moving the lights further away from the subjects also. Any photographers have any suggestions.

Perhaps polarizing sheets on your lights, and a Polarizing filter on camera. Maybe able to adjust one against the other to control the 'Glow'.

With digital, filters are not generally needed. I just use one to keep the lens clean

That's because the shirts that glow in response to UV light are glowing in visible light which a UV filter will not cut out. Phosphorescence converts a high energy photon (UV) to a lower energy (visible). Phosphorescence is not limited to UV wavelengths to excite the glow. Blue light will work in some cases also.

.......

I think you missed that he's filtering at the light source to
reduce phosphoresence. He did not mention lens filtering.

Not sure what the actual light source is, but hopefully it's
not strobes. Filament lights, or perhaps tungsten balanced
LED, would put out far less UV in the first place than xenon
tubes !
