Have a look at the Hoya Pro 1 Digital filter.
The older I get the faster I was.

I would recommend you buy a larger CPL filter and a step down ring.. As quite a few Pentax lenses now have a larger filter size,,

That's a UV, not a CPL.

Try a camera shop somewhere and see if they have something suitable in their clearance or S/H bin.
You don't actually need the circular variety for Pentax cameras though if shared with other brands you might do.

This might be worth a punt: https://www.ebay.co.uk/itm/62mm-Genuine-HOYA-Circular-Polarizer-Filter-CIR-PL-CP...

I bought a new one this summer from a local company - SRB Photographic in Dunstable. It is well-built from anodised aluminium and multi-coated glass, and its movement is smooth and suitably damped. Not having used one before, its effect of deepening the blue of the sky was pleasantly surprising. This is Castle Pomeroy, a ruined castle in Devon:

The problem with this is that the lens hood will probably no longer fit over the large filter and stepping rings.

I have a 49mm Marumi CPL which is superb - I use it on my DA Limited lenses with no visible image degradation. I think mine is the smaller version of this one (Super DHG): https://www.amazon.co.uk/Marumi-Super-circular-polarising-Filter/dp/B001F7BFMY/r...

But there's a cheaper "slim" Marumi CPL here which has excellent reviews (though not many of them): https://www.amazon.co.uk/Marumi-Slim-62mm-Circular-Filter/dp/B00NXT41VO/ref=sr_1...

I also use the Hoya Pro 1 and I'm very pleased with the performance, although I expect that any of the premium brands would work just as well. However, in my opinion it's just not worth while buying a cheap 'knock off' version.

The point about the benefit buying a larger version and using step-up/down rings is a good one, but don't forget to also buy a lens cap of the same size. But note Jonathan's point about the lens hood not fitting - that can be a real pain.

I have a cheap CPL (67mm I think) I used on the first day in San Francisco a few years ago on my Tamron 17-50mm. The pictures were awful: poor contrast, dull colours and a slight drop in sharpness (though that could have been my perception due to the first two issues I mentioned). I took it off and pictures were much better.

The most noticable thing I've seen with cheap ones is that they can give an unpleasant colour cast.

Unfortunately SRS weren't discounting the one I mentioned above at the time I got mine...

With the non-slim filters, chances are that you will notice vignetting at the widest focal ranges.

It was for this reason why I always purchase the slim models (dearer but better).

To date I have a Marumi Super 72mm and a Hoya Pro 82mm, equally as good.
