CPL on top of a UV protect?

Long story short— I use clear glass protectors or CPL or ND filters. UV filters are for film and high altitudes.
Bummer.
Short story to begin with: I have a UV (or skylight) on the lenses for protection.
I don't notice any difference in the images acquired, so I'm not worried about it.
Still waiting for the filter police to show up....

Old habits die hard… But you probably won’t miss half a stop of light.

A different take, when I started in photography in 2019, I began with a heavy investment in lens. I made sure I had protective glass on each lens. Study, research and working with master photographers it became clear they do not use protective glass. I insured all of my equipment instead. I have never had a photography claim. Clear filter for blowing sand...OK, but that is not the same thing. Have I seen a person drop their camera and lens is saved by $200+ filter, one time. Why do not the manufacturers of expensive lenses not push one more piece of glass as a solution?

I had a 200 - 400mm F4 Nikkor, purchased new. For a long time I wondered why there was a 'filler' in the bottom of the case. Then I read the manual.
The front element was a protective piece of glass (filter) that came attached to the lens. The filler was actually a pouch to keep the front element when you didn't want to use it.
Most of my photography back then was on ocean beaches, so I seldom took the piece of glass off.

NOPE!
Not at all.
A UV really cuts a half stop?
Whooda thunk it, it looks clear.
Not a habit, simply not worried about it.
There's a difference.
I had three choices, skylite, clear, UV.
Eenie, meenie, minie Moe.
Lets pick this one,
and away we go.

Photography is full of self-taught practitioners. I have been in two classes (well...a workshop and a class) with a published photographer who also represents one of the "big three." He openly admits to being self-taught. I like his classes, and I like him. But I've learned to weigh what he says. Especially when he discusses complex processes. Because sometimes he becomes more procedural than logical. And...he admits that there is usually more than one way to do a thing, but he only teaches one way.
The same thing was true in the two photography classes I took many years ago. Most of the big ideas were taught spot-on correct. But some of the details were absolutely wrong. Usually because the instructor didn't understand the underlying mathematics.
No glass filter is going to reliably protect a lens from catastrophic damage. But it will protect from careless scratches or spills.
I fell with my camera a year and a half ago. Landed on the hood and pushed it back over the barrel of the lens. The filter ended up with some grass stuck to it. There was no damage to the lens or the camera. DO NOT TRY TO TELL ME that filters and hoods are useless for protection. (And yes...the lens cap was off because I was actually taking pictures.)

That's why I analyze each "statement" individually. So many are simply opinions. Many are based on erroneous interpretations.
I'll never tell you filters don't protect and are not worthy of using.
Back about 1975 a guy came into the camera store where I worked part-time with a camera that got caught underneath a power seat in a car. The filter was cracked and outer rim bent. Some work with a set of filter wrenches, a replacement filter, and he was on his way. Luckily the threads of the lens did not get damaged. Ever since I've used a filter for lens protection (plus the hood by default, but I use it primarily to keep out stray light.).

Half a stop of light? Wow that could mean hundred or even thousand of dollars worth.

Easy, take off the UV while using the CPL. Replace the CPL with the UV when done. Consider cleaning both during the processing.

Depending on the filters used, there is also a chance of losing a stop or two of light. I do not see anyone mention this but I have definately noticed it when combining filters. I agree with the statement that it could affect the AF. That makes sense if you are actually eliminating light hitting the sensor as it seeks certain details. Any of the "experts" on this thread agree with my hobbyist assumption?

Yes. Remove the UV. The CPL will give as much physical protection by itself. Using both adds nothing, and subtracts a little.
The screen-door analogy. If you are looking through a layer of window screen you notice that it is not as sharp as looking through just a glass window. If you had two or three layers of window screen you would easily see a tremendous drop off. Obviously additional layers only degrade things more. They never add any quality.
With filters the effect is nowhere near as extreme, but still, adding one on top of another never adds quality.

While true, I believe the original question was about leaving the UV filter on the lens and adding a CPL
Not combining filters in general.

In general, combining filters when there is no reason to is not recommended. It's not much effort to take off the UV filter first.

Real world ? No. Hawgsterland ? Depends on whether the viewer has been informed about the illegally stacked filters. Which holds sway legally, the confession or the evidence ?
