37mm Circular Polarizer Filter with 24 Multi-Layer Green Coatings HD/Hydrophobic/Scratch Resistant Nano-Dazzle Series

Item is delivered within time, product according to the description on Amazon, good. Tip: Do not overtighten the filter frame when attaching it to the lens, otherwise you will have trouble disassembling it from the lens.

I had been used to a Hoya Pro1D for years and wanted to try this Pola for my handyman (Nikkor 24-85 VR on the D750) because I didn't want to spend too much on it. What can I say... optically very good, I would say absolutely at Hoya level, stable construction, even too much as I find that the rotating ring is too friction for my taste (the Hoya will be much easier). Another Note: It's a little tricky to unscrew from the lens, but I've found that applying a slight force with your thumb and forefinger, as if "squeezing" and ovalizing it, is enough and it pops right off.

Eliminate reflections and boost color

These are well made filters, the ring is very small so they don't cause vignetting even on wide angle lenses. These screwed smoothly onto my lens and stayed on securely. These circular polarizers only reduce the light a little and once screwed on there is an outer ring that allows you to rotate the polarizer to get the best effect.

You can use these to reduce reflections from things like water, glasses, and windows. Because it reduces reflections, you can look down into the water, making it look clearer and cleaner. It also helps provide a clearer sky image when taking photos outside.

This is the “D” series filter, they also have a “K” series. I'm not sure of the exact difference between the two as K&F's own website doesn't really explain it. From what I can tell the "D" series (these) are a slightly more expensive design with more layers of coatings including water/oil repellent coatings on both sides. They describe these as "waterproof".

Definitely well-made filters that do the job.

It has been used for a while, you can see it in the picture, it is very clean, this price is really worth it, no worse than 3,400! ! Enjoy the early start!

I mainly do landscape and street photography. I don't use many filters, but sometimes I use neutral density (ND) filters and neutral density filters for special situations.

However, I often use a polarizer in bright sunlight. It can help tame unwanted reflections and is particularly useful for increasing saturation and contrast in the sky.

This filter snaps easily onto my 77mm Nikon SLR lenses. The outer filter ring rotates evenly. (You'll need to align the filter for best results.)

As with every polarizer I've used, this one reduces the light hitting the camera sensor. This reduces incident light by about one and a half stops.

As far as I can tell, the mechanical and optical quality is good.

This provider offers a variety of filters. The pricing seems very reasonable

I have other K&Fs and they have served well. Picked this up to go on my fancy 50, a "required" lens for "serious people". I use it occasionally but not the best for birds and other wildlife. I assume it will help in the bright sun for flowers and such, but there is neither at this time of year.

I was lucky enough to have the foresight to have a polarizer on my lens when photographing the geysers in Yellowstone NP. The difference was overwhelming. Since then I've always done my best to have a CPL for every lens, or at least one that could use a suitable adapter.

The quality is sufficient for the occasional use of a lens, and the price is right for it. Recommended.

I still shoot landscapes with a DSLR and one of the 5 filters I use most is a circular polarizer (CPL) as it helps filter out the scattered rays of light that cause glare on water, windows, wet foliage and the wash out the normal blue tint of the sky.

There's not really much to say about a filter though — is it doing its job? Yes.
Does it do its job well? Yes.
Does it do its job well enough to be worth the purchase price? Absolutely yes — the sale of one or two prints taken with this filter will cover the acquisition cost in profit.
Does it make it easy to take landscape shots that will sell? Dexterity plays a big part in this, but this filter helps limit some sources of glare that can (not always) ruin landscape shots. It also works well in light tents and other situations where you have multiple strong light sources coming from different directions.

Being multi-coated glass, they've been pretty careful to limit how much light this filter reflects and once installed on your lens, it's able to aim and shoot fairly accurately, even if you're still using the Use Green Box (Full Auto Mode) on your camera. This is my 4th CPL filter in different lens diameters; I've never had one so big or so bad that I felt either way strong.

Anti-reflective effect is good, ready to go

I purchased this 82mm circular polarizing filter to use with both my Sigme 24-70 f/2.8 E mount and my Canon 24-70 f/2.8L II lenses. It's just a perfect polarizer for these versatile zooms.

The lens is extremely well made and the circular effect is smooth as silk when attached to the lens. The high-quality multi-coating ensures details in photos and videos without artefacts or haze and ensures excellent focus accuracy.

Polarizing filters have many uses, including deepening the color enhancements of skies and landscapes, especially in bright light conditions. In addition, the circular settings can be used to shoot through windows clearly and without reflection, and to take pictures or videos through water. For example, this filter can be used to capture perfect images of Koi (Japanese Colorful Carp) in a pond without light bouncing off the water's surface. There are other uses as well.

To operate, all that is required is to point a camera at the subject and rotate the outer plane of the filter until the desired effect is visible through the viewfinder... or on a screen. Easy peasy.

I own a number of K&F filters of various types including UV, ND and diffusers. I trust the company's products. This is excellent value for money compared to much more expensive polarizing filters such as those from B+W and Hoya while offering virtually equivalent performance. Fantastic!

It's an unequivocally high FIVE STARS from me, along with my honest and very warm recommendation. Improve your photography and vlogging! get this!
