55mm CPL Circular Polarizing Lens Filter for Camera Lenses – Optical Glass Lens Filter Suitable for Outdoor & Professional Photography by Fire Filters

A tenth the price of some filters I'd been looking at! I have not used this much yet; I bought it because the new Nikon 10-20mm ultra-wide lens I bought as a gift for my oldest friend (me) takes a very large 72mm filter. As I may not use this lens very much in comparison with my others, I decided to try this rather than a top-grade pro filter that costs nearly 1/4 the price of the 21-element lens itself.Surprise! Deluxe foam-in-plastic case in a classy box. Free large microfiber cleaning cloth. No defects visible in glass or metal. Fits lens perfectly; very easy mount/dismount, and the filter turns smoothly to adjust the polarization--yet holds setting well. Optical density seems a bit lower than my other filters, but the effect seems the same. Lower density can mean a smaller filter factor (can use a faster shutter speed or lower ISO sensitivity setting), but could mean less effective polarization. For now, I can say there is a good amount of sky enhancement and reflection reduction (like from a fishtank or train widow).Coming back to this, I see this item may no longer be available. Good Luck! You can find a decent CPL Filter from many other mid-range companies like for a reasonable price. I've bought about eight over the years for still cameras and camcorders, and only one (Vivitar 58mm) was improperly manufactured. Though marked CPL, it may have been the wrong type. Originally polarizing filters were linear type. These may interfere with automatic exposure and autofocus on newer cameras. Make sure which your camera needs (check what kind its manufacturer sells).Tips: ALL screw attachments can crossthread (jam). Lens-filter threads are very fine, so be gentle and NEVER EVER use force. Fingertips ONLY. And polarizing filters need to be held by the edge, not the top ring (designed to turn freely), to attach or detach. If I have difficulty at first, I turn the filter backwards (counterclockwise from the front) slowly until I feel a tiny click. This means the start of the filter thread has reached the start of the lens thread. You can then turn the filter gently clockwise to mate. If you have trouble, repeat this. The same trick works for all threads. Forcing jammed filters can require COSTLY out-of-warranty camera repair.Some questions I've seen posted indicate some users may not fully understand how to use a polarizing filter.* All lens attachments I've used affect the amount of light the camera sees. Sometimes you WANT to do this, but usually not. I never keep a CPL filter on the lens just for protection; use a clear or faintly colored UV filter instead: Cheaper, easier to attach, and maximize light.*The back of the filter attaches to the camera lens as described above; the rim at the front of the filter is supposed to turn easily so the filter can be rotated to get the best effect. The effects I've used are: * Darken sunny skies to improve clouds in outdoor photos. Most dramatic when lens aimed 90 degrees from the sun. * Minimize reflections: Scenics from tourist train windows had reflections of interior. CPL made videos usable. * Reduce surface glare. Change appearance of eyeglasses and glassware; help get professional-looking results.Experiment and enjoy!

I haven't actually used this polarizer yet, but the quality of the aluminum ring is very good, it turns smoothly with no gritty action.Made of optical glass in Japan, yet. I can remember when you wouldn't buy anything made in Japan.The tiny painted markings are clean and crisp. Having been involved in the marking of parts, I know how difficult it can be. If they pay this much attention to the markings, I have high hopes for the actual usage. I was a quality control inspector for 45 years. If I say it's good, it's good.I will revise post after I use this, But for now it gets 5 stars for quality appearance.

A good CPL makes a real difference especially when photographing through reflective surfaces like glass and water. The only concern is that any glass placed in front of your lens can introduce distortion. However, since I already dropped my Sigma 24-105 and cracked the $90 filter rather than the $900 lens, I feel the benefits substantially outweigh the negatives.

Got a chance to use it on the lake, it absolutely blocked the reflection from the water so the objects I was photographing stood out instead. Will update after taking out in bright sunlight, etc. Btw, comes packaged very well and they also include a very nice lens cloth w/it! Very happy w/ purchase!

At first, I thought it was not working when compared to my B+W linear polarizer. But then I noticed that my B+W circular polarizer was also not working. Then I figured out that I was holding them backward and that matters. Turns out this works well. It passes a lot more light than my older B+W.

Bought this to take on an extended outdoor trip. Its the first polarizing filter I have used, so maybe my expectations were too high, but it didn't seem to have much effect, and was also a bit difficult to adjust. In the end, I left it on to protect the lens. It was inexpensive and came well packaged considering its price.

Good quality for money!

Good CPL filter at very low price. However color seems turn yellowish. Next time I will set white balance before put it on my lens. Hope it gets better.
