I would not personally trust those to degrade image quality. Probably fine for a casual user, but somebody who pixel peeps may notice. You are, after all, putting more glass in front of the lens.

Other than that, CPLs are great to have.

I wouldn't trust no name glass in front of my lenses. Sounds like a good deal but too many things will go wrong - diffraction, chromatic aberration, color shifts, flares etc. Especially if you're shooting with fast high quality glass, this CPL will definitely degrade the quality.

>4.5star over 700+ reviews on those.

Do you have a review that says it has any problem or is it just brand snobbing as usual? I can understand avoiding cheap Ebay no names, but these really aren't that bad... obviously no B+W, but 95% of people aren't shooting with professional lenses either.

Even cheap no name CPL's go for $20-30 usually... so <$10 is good for people who only want to tryout a CPL.

I mean by that metric, even the most expensive filter is still "more glass" in front, so no protection is best then and hope your lens don't contract STDs..?

You're not wrong.

I invested in B+W UV filters for a lot of my lenses when I was first starting out collecting gear. I eventually stopped using them, as the shooting I do generally is pretty low-risk and additional protection beyond the lens hood wasn't worth it for me. Now, the only filters I carry are CPLs, and they don't stay on the lens after I'm done shooting. I'm of the adage that if you do insist on UV filters, at least stick to a known-good brand. I don't necessary endorse (your use cases may differ) buying the best quality, most expensive stuff (law of diminishing returns), but something from a known filter glass specialist is a good place to start.

But, $10 to try a CPL is a good place to start.

I have one of these Platinum CPL filters from a previous sale at Bestbuy and decided to test it.
Below you can find 3 sets of pictures of the same subject with and without the filter.
Please note that i didn't care about the polarizing function, just the quality degradation caused by an extra piece of glass.
Shot on the tripod at ISO 100, F 7.1, shutter speed adjusted to match the exposure (2-3 stop)

Thanks for post, but pic links seem to be broken.

Was there degradation in the pic with the filers?

I didn't notice much degradation and I posted it for other people to share their opinion.
The links work fine for me....not sure what's going on
If you can suggest a free hosting more friendly for RFD I will repost them

The filters have good reviews, with the exception of the 77mm CPL. Ordered a couple of the 58mm filters. Thanks for the tip.
