Not so fast. We don't know what filter the OP was using. Some polarize filters are real bad, whether linear or circular. I had a Kenko c. pol (gave it to the guy who bought one of my cameras at the time), which produced purple casts depending on the polarization. I do have both types and use them on my DSLR lenses. I never experienced such bad results with my linear pol filters otherwise I would not make the statement I made. I think the filter the OP used was bad (or of a very poor quality). If I have some time, I'll take a few shots with my G1 using both, a c. pol and l. pol. and will post the results.

OK but your results for a 43 camera are not relevant to this discussion - they do not use a mirror. I would expect a linear polarizer to work fine on your G1.

If that's the case, people would not recommend c. pol for all P&S as weel as DSLRs. The justification for recommending a c. pol vs. l. pol has nothing to do with the mirror but with the digital technology (as opposed to film). People claim that c. pol is for digital (not necessarily DSLRs). The other thing about the post you referred to is that you'd be surprised how many people don't realize that the front element of a pol filter turns. Many think that all they have to do is attach the filter to the lens just like an UV filter. The image will deteriorate depending on the polarization.

tullio, i respectively have to disagree with you on cheap filters, as i have used cheap filters in the past and have since switched to tiffen HT, & singh ray filters, and there is indeed a significant difference in "my images", there is visible softness,color shifts,and muted contrast when using cheaper filters, now the color shift and contrast problems could be fixed in post but the softness is unrepairable. the theory of putting cheap filters on cheap lenses "imho" is wrong because you are already starting with less than optimum glass in the lens, and cheap filters only degrades images further. again this is what i see in my images and is not scientific, others may have different results. i am however convinced there is no equal to the singh ray filters that i use, the clarity & colors of the circular polarizers & nd filters is stunning.

Jeeezo-flip, I thought the Tiffen HT filters were expensive until I looked at the Singh-Rays.

ted, yes they are very expensive, i was lucky enough to have a job where i could afford them, but at present, like a lot of people have been laid-off so they are way out of my range right now. but for me the singh ray filters was the biggest leap forward in the quality of my images. i have won or placed very high on several state park photo competitions and out of all my submissions only the images with the singh ray filters have won, even though i felt the composition & mood in other images(without signh ray filters) was better than the ones that placed higher.

tkurkowski Feb 28, 2010 8:46 AM

Charles, that's quite an endorsement. The images in their brochure are impressive. But they are out of my price range and I still have a job.

I hope you get a job soon.

PS: It surprised me that they said they don't believe multi-coating is a good idea.

I can see that multicoating a polarizer has the possibility of causing problems. Is it just that instance? I know of no one that believes that multicoating is the best way to increase light transmission.

I would only use C-pl and a Haze 1 as a warming filter.

They don't MC any of their filters.
