Other than reading articles, I do my own tests and with good quality filters (B+W, but the past year I tried Sigma WR, same level and less expensive https://www.amazon.it/gp/product/B00NIHDMMU/) don't impact the visible quality of photos in normal conditions. I usually remove them only with the sun in the picture. Thanks to filters I saved at least two front elements ($$$) and, considering that the filters mounted on the most used lenses are covered with slight scratches after a few years, they also preserve the commercial value of the lens.
I have been using filters like that since my analog days, for protection. My camera dealer, a frie4nd who owns a pop and mom store in everything photographic, swears by them. He also does small repairs etc., and he says that of all the accidents he has seen with cameras, other than warranty issues, when it has to do with the lens, he has never had a lens with a filter that got other damage than the filter itself, but without, it always had to be sent back to the manufacturer for expensive repairs, or replacement with another lens. The most common accident is people dropping it from relatively small heights, or bumping into something, and a filter is an excellent protection for those types of accidents.
The filter ring is commonly made of metal, and that with the extra layer of glass, which also increases rigidity and makes it more sturdy, prevents the lens from getting serious damage most of the time.
His favourite filter brand is B&W, but if people do not want to pay that amount of money for a high quality filter, he has an alternative as well, forgotten which brand that is, but it is also an on both sides multi-coated filter. He doesn't do Sigma filters, however, for a very simple reason: colour cast. If you put a protection filter of several brands next to each other, the Sigma has a yellowish colour cast, where the others he carries are neutral. We are talking UV and protection filters here, of course.
Kind regards, Wim
Sigma has gone a long way since the yellow cast days, that's something from the past, we are talking lenses here, it would be a pity if they didn't upgrade the coating for filters
