HoyaHD3 HRT Circular Polarizer - 67mm - Re-Certified for 100MP+ Cameras with Ultra-Hard Nano Coating Technology and High Rate Transmission Film - Stain Resistant and Waterproof Filter

This is an amazing lens! I’ve ordered several others before, but most of them affected the image quality or added noise. This one delivers a clear picture with minimal distortion or color shift. It’s by far the best lens I’ve used — highly recommended!

so great - clarity banging. best filter I have purchased.

First, this does what any good circular polarized is supposed to do. But there are a couple additional benefits---A-most CPL's block 2 to 2-1/2 stops to light but this one passes 2/3 stop more according to Hoya (maybe even a full stop per the metering on my camera. This is not trivial.B-the HD3 coating is advertized to be very tough and to resist fingerprints and dust. To my surprise I have found this claim to be true. It actually take some effort to leave a fingerprint and dust tends to simply fall off.

Does not block as much light as most polarizers but appears to work as well. Used extensively on trip on Danube and also used it some on a bus to reduce reflections in the window as we traveled. I have used polarizers for over 50 years and it works great. I was difficult to separate from the 67-82mm step-up adapter. I am replacing the adapters I use and will carry a lens wrench in the future. This is a rather common problem in my experience.

Found large swaths of dust and gunk in the corners/crevaces of this polarizer. No matter how many sensor swabs and microfiber cloths I used, they were very hard to clean. Not sure why or how this happened, but my next purchase will probably be from Bhphoto. The filter itself is great, so I still rated this 4 stars.

Simply the best filter.No colorshift.No flares.Really good coating, no traces on it.Only minus is a price.

The glass and coatings are 10/10. Clear and crisp with no colorization. Superb optics. Industry best coatings. CAUTION - the metal exterior ring is VERY thin and makes it difficult to mount and dismount. The polarizer ring is easy to manipulate, however, attempting to remove the mount-ring with fingers or a filter wrench is overly difficult. Would have been better a few mm's thicker. 100% purchase this polarizer if you don't intend to move it often.

This is the finest polarizer I've ever used, the only flaw is the high price oh, but it's truly worth it. The reduced light loss alone is worth the price of entry but oil and water resistant coating seals the deal.
