Circular Polarizer Thoughts

I occasionally use a Tiffen circular polarizing filter in my video work on a Canon lens, and my dad had a Hoya polarizing filter for his still camera when I was a teen.  Are there any opinions on these for the Q2…seems prices vary $19-$100 US.

I've had a number of CPFs.  I settled on this one, albeit pricey, it is of excellent quality.

Just FYI, we can't see the item you've linked because you linked to your personal order history.

Actually there is no need for a circular pol filter. There are no mirrors in the light path. A linear one will do just as well.

Exactly what I was about to say...

 A circular pol filter is a linear pol filter laminated with a diffuser behind it to depolarize the light.

With greatest respect, not quite true - it's a linear polariser with a quarter wave plate behind it to create a rotating polarisation.

This explains it far better than I can: https://www.apioptics.com/about-api/api-blog/api-news/how-circular-polarization-works/

Yes, that is quite right. I attempted to keep it simple. I doubt that quarter wave plate rings a bell with many…

bottom line is a CPF could be of use depending on what and where you photograph. The CPF will reduce/eliminate glare on water, pavement/street, flora, leaves, etc of course making object darker, so I would be aware of that if you also use any BW contrast filters. You may get more contrast than you want or expect.

I used long time ago pol filters to give the Photos more "Pop" during film times, or to reduce glare.
Today I use it anymore as more "pop" can be reached easily while editing and if there is glare/reflection i try to use it as stylish part of the composition.

I would consider to buy a pol filter only if I would shoot things I need to reduce the glare or reflections from shooting thru glass for example,
or intense macro work but for this I consider the Q2 not the right camera.

If so, I would get a B+W or Heliopan, however a high quality product.
