I've no concern with angles, time of day, or light intensity.
I prefer an LP vs. CP, but my camera focusing system dictates which I need to use.

I have a new Zfc with a 24-200 full frame zoom. I have been keeping the polarizing filter on, however I wonder if there are times when it is better to not utilizie the polarizer. Pardon if this is a basic question; I am a serious amateur and still learning about mirrorless. My main topics are dinner parties, sunsets, and landscapes. Thanks.

I'm "almost" new to photography, just a couple of years and do mostly landscapes. Here is an example where I used a polarizing filter to reduce light reflection from the water. This way I was able to show the objects below the surface.

Use it only when you are going to be using it. Why would you keep it on?
A polarizer works at 90º to the sun, for maximum effect. Also, it can reduce some reflections.
If it is not helping you, why would you use it?

An excellent example of a shot you couldn't have got without a polariser :)

No need to look it up I've done it, several times.
It works as long as the front filter is linear, and the CPL is the right way round.

Thaz exactly why I said that about HALF of those who attempted it would fail.

Without that specific advice, its a 50-50 crap shoot which way any user would stack their filters. Important specific advice, better late than never.

Acoarst there will be those to whom ALL PLs are CPLs (helloooooo Hawgsters ...) and for them failure is 100% assured regardless of how they stack their filters :-(

One thing I've noticed with UHH posters is it that if you say something is "White" there will always be someone who will say it's "Black". I look to the science. As far at this discussion is concerned, Please, do what you want.

What's worse is those who can't make up their minds and call everything grey!

Polarizers do cause a bit of light loss, roughly about one to two stops depending on the polarization intensity.

Also, you may need to remember to rotate the filter based on light direction

Light loss depends on the type of polarizer. A stop or two is accurate for a standard CPL, but less than a stop can be had with a high-transmission CPL.

I've moved up from standard CPLs to the high transmission flavor. I own several because I, like the OP, keep one on my outdoor lenses most of the time. I don't like moving them between lenses. Most of my shooting is outdoors where a CPL is useful. I don't keep a filter on my 16mm lens (a CPL wouldn't work well) or my 24-70mm (I use it only indoors).

Heliopan, Breakthrough Photography, B+W, and K&F Concept are my brands (yeah, I'm as loyal as a two-bit hooker). My K&F Concept True Color Nano-X Series is the best bang for the buck -- it's a surprisingly good filter for around sixty bucks.

There are inexpensive filters out there, but whatever you do, don't put a low-quality filter in front of good glass.

Thank you for granting Grace and Permission.

I doubt many people measure. I would assume they simply put on a CPL and twirl it to see if it helps. Still, he DID take the time to establish there was a specific angle for complete polarization - so let's give him credit for adding a his drop to the catalog of human knowledge.

IIRC from third grade, measuring can involve numbers. Hawgsters and numbers do not get along, except acoarst for numbers having no mathematical values, serving only as names, such as "150-600", "ISO 12800", or "ND3.0".

They DO have mathematical values, just not in feet, meters, or furlongs per fortnight.

So when you say standard are you referring to circular? Clarification.
