polarizing filter

rabblefrabble · 11-28-2014, 08:34 PM

I keep seeing people mention polarizing filters and wanted to know if they were worth it and any brand recommendations?

They're among the few filters that can't be replaced by post-processing, so yes, they're worth it IMO.

Adam, Thanks for the link. The article mentions that pentax cameras don't need a CP filter. Would you still recommend a CP over LP?

CP's are mainly used for DSLR's, LP's are used for Film SLRs.

Would recommend getting a CP. It'll even work on film SLR's also

Thanks! Any recommendations on brand that is good quality but not the most expensive?

Tiffen is one brand to look at, especially right now since on adorama.com seems to be having a clearance on some of their Tiffen CP's (http://www.adorama.com/catalog.tpl?op=itemlist&cat1=Lens Filters&cat2=Polari...iffen&sf=Price), a majority of them are under $50 bucks (depending on what you're need is, filter wise).

Great, Thanks for the help!

What you choose to buy depends on your budget and what lens you intend to use it with,putting a cheap glass filter on a high quality lens doesn't make much sense.If your using a wide angle lens you'll want to look for a slim filter to avoid vignetting.I own a Marumi CP filter that i am very happy with and reviews say it performs as well as some costing twice as much.It's your coin but my advice is do a little reading on the subject and make an informed choice based on quality and price.

Don't be fooled by warnings against "cheap glass." I used to buy CPs from B+W, an expensive German outfit. Two of them literally fell apart! Whereas the Chinese-made "Agfa" filters are solid and very inexpensive.

Yeah, cost is no longer necessarily an indicator of quality. But the problem is that so many brands make multiple series of the same kind of filter, which makes it difficult to give accurate recommendations. I suggest mostly that you buy it from a reputable store, so you don't get an internet fake. And research the specific brands that are available for you, within your budget. No need to look at dozens of tests if none of those filters are available to you anyway.
And I do recommend you get a polarizer. A good one. If you have lenses with different filter thread sizes, you can buy step up/down rings to bridge the gap, so you don't have to buy as many filters. Pentax mostly uses 49mm and 52mm, but there are other filter thread sizes as well.
Also, using a polarizer with ultra wide lenses (wider than 20mm or so) can cause parts of the sky to be blotchy, dark. Just letting you know.
