Polarising filters can be difficult to muti-coat.
No filter is going to pass exactly the same mix of wavelengths as would no filter at all. Though with an ND the difference may be slight (as it should be) there will inevitably be some difference in the mix of wavelengths passes, and a consequent slight difference int he rending of some colors, and the darkening or lightening of some colors. This is much more pronounced and obvious the denser the ND, to the point where 10-stop filter and the like are likely to produce a color rendition that is difficult or impossible to correct during processing.
Hi-tech has high quality filters. They tend to be a bit warmer than Lee.
Just to be sure I understand ...If anything, they are better, but I think the effect is harder to recognize when it doesn't get darker at the same time. At half-press, the live view compensates.Have you seen any tests to verify the HT are just as effective ???A "standard" CPL can reduce the exposure by 2 1/2 stops, measured from with and without. That can be a lot at the narrow apertures used with landscape. That's the main reason for the preference for the high transmission types for hand-held use.But before that, why specifically are you thinking of buying a CPL? They can be useful in some situations, of course - but be sure you understand those situations before you buy.
Hi & thanks for your answer.
bearing in mind I have limited experience, & maybe over thinking things.
I had the idea that When we eventually get some good weather & are allowed out to take photos I would like to do some more landscapes.
I have a few subjects & ideas in mind.
In some instances I may want to eliminate reflections, in water, enrich colours & increase contrast particularly between clouds & sky.
I also had the idea that for early morning / late evening shots (though I do understand I could use Nd filters) that maybe using one would allow me to slow shutter speed down a little to create some movement in the clouds while still maintaining the desired effects mentioned above.
Hope I got that question right:-O
cheers. Marc.
I can accept more light loss IF it indeed is more effective.
A name brand linear might be better than a cheap, generic CPL, but there are no premium versions, like there are for CPLs.Just to be sure I understand ...If anything, they are better, but I think the effect is harder to recognize when it doesn't get darker at the same time.

Are you saying Linear or Circular polarizers are better ???
Are you saying Darker or High-Transmission polarizers are better ???
My choice of course would be that (cheaper) Linear AND High-Transmission are best and available multi-coated and hydro-phobic ....
My post was NOT an advice. I simply described MY PRACTICE which I FEEL MAYBE relevant to the OP's response my post.
1st off, great post!
I normally use leefilter, LEE100 System and Polariser are a great invention for a clear image. It is very impressive, I always recommend my friends to use it...
