Opinions Wanted on 77mm Polarizing Filter

I'm looking to buy a 77mm polarizer for my EF-s 10-22. Does anyone have any opinions on the Kenko version? They seem pretty reasonable.

Any known Ebay scams or knock-offs one should be aware of?

Any other reasonable brands to look for?

I suggest a more expensive "slim" polarizer. You'll avoid nasty vignetting at 10mm.

I have two polarizers. One cheap one expensive. The expensive one is delaminating. Cheap one is three hundred years old and is just fine. Spend your money accordingly.

The B+W 77mm F-Pro Kaeseman Circular Polarizer works great on my Canon 10-22mm. Absolutely no vignetting at 10mm.

I am certainly no expert, but I was told many years ago that if the CPL works it was made correctly, and price has absolutely no bearing on the outcome. I have an E-Bay CPL and it works great and no vignetting. My .02 for what it's worth.

Vignetting is hardly the only criterion for determining effectiveness of a filter. Multicoating cuts down reflections and flare that uncoated or single-coated filters are prone to. Not all polarizers are truly broad spectrum (work for all wave lengths of light), and less expensive filters frequently have uneven glass that introduces distortions. You get what you pay for. B+W MRC filters are optically flat, very well multi-coated, and have good broad-spectrum characteristics, as do Heliopan SH-PMC and Hoya S-HMC.

You get what you pay for. Call Adorama or another B + W authorized dealer and get a thin, multicoated filter.

If you get a B+W filter, skip the slim version...you don't need it for the 10-22 so no reason to spend the extra money. Either version of the F-Pro MRC polarizer (Kaesemann or non-Kaesemann) will not vignette on the EF-S 10-22.

Another vote for the B+W (MRC) F-Pro or B+W Kaesemann CPL filters.

Quoted for emphasis. The multi-coating is huge, and broad-spectrum helps.

I have a Hoya MRC, and it's beautiful - though I have to admit that it's difficult to get perfectly clean. Others have said the same thing, and the next one I get will be a B&W.

My Hoya is a Slim version, and it has it's pros and cons. Pro - no vignetting when ultra-wide. Pro - it has a knurled edge parallel to the lens, allowing you to turn the CPL without taking the hood off. Con - this knurled edge means that I can't stack another filter on top of it (though I can stack one under it).

I see little sense in getting a Kasseman, unless you really know you need one. That's just me.

Make sure you get step-down rings to fit the CPL to your other lenses. For $5 each they're well worth it. But note that putting a 77mm CPL on a stepd-down ring to fit a 67mm lens means that you most likely can't put that len's hood on.

Get a good CPL in a common size and you will use it for the rest of your life.

cpl + sky + 10mm = some funny effects

Very misleading info. Yeah it does happen but is very controllable. Never not once has it stopped me from getting spectacular results at 10mm.

And another.

I've got the B+W 77mm F-PRO and it's awesome! Pricey but worth it.

NO vignetting on my sigma 10-20 and 50d, and it is not the slim version.

I only see vignetting when I stack more than 2 filters.
