I leave this filter on all the time now - adds a sort of filmic gentle glow to highlights. I have the more expensive Tiffen equivalent on another lens and quality seems to be about the same. Great quality at a reasonable price!

Totally love it, good alternative for glimmerglass 1. It makes pictures a little bit moody, reduces the sharpness and gives me the look of the pictures that i want.

QUALITY 10/10
BOX 10/10
PRICE 10/10

STRONGLY RECOMMEND!

Good Value for money compare to other variable ND filters. I wish they make marking on both side but other than that, it works.

I reviewed this product in May of 2023.

I really enjoy K&F filters for the selection, the subtle effects, and the price point. This filter is another one that I'm keeping in my kit for adding some nice effects to my images. I like to refer to it as the shimmer/glimmer filter as it does a little of both in the right lighting.

To start off, this comes in a really nice case that you'll appreciate. Not the cheap plastic junk cases a lot of filters show up in. The filter itself is really well constructed and has smooth threads that slip right into the lens threads without issue. I used this for a few different shots and never noticed any color differences when compared to just a UV filter or a bare lens. I attached two images to this review, one with the filter in place, the other with a UV filter in place. There is a slight difference in the glow and effect that adds in some character to the shot. Very subtle in the images I uploaded but more pronounced in images where there's more lights, lower lighting conditions, or very direct hard lighting.

I enjoyed using this filter and can easily recommend it if you're looking for a softer look that has some glimmer effect to it.

Just beautiful.
Love this Shimmer Diffusion filter.
Is amazing

In a world where we chase the ultimate sharpness in images and video, diffusion filters are a fun getaway from that rat race. This particular filter is, in my opinion, fairly "low power" in most situations, so you can safely add it without causing an overpowering effect like many other filters, especially in the budget section. This can be used for portraits to give a slight glowing effect and soften up some of that sharpness while maintaining image detail, or for landscapes to add some glow to any light sources in the scene, along with any variety of scenarios you might come up with. If you have the time, I'd recommend trying it out any chance you have and seeing if you like what it adds to the image. These filters are very subjective and what may work for one person may not for another, and in reverse as well of course.

I found this to be most effective when there is some contrast and drama to the light. In the flat midday sun, it was actually difficult in my case to find any difference at all other than some mild softening of the image. However, in my night test, it added a wonderful glow to the various light sources, making the image much more appealing and less harsh.

One of the best things I noted about this filter is what it DIDN'T do. I didn't notice any color cast or discoloration caused by this filter. Many other filters struggle with this issue but in anything from midday sun to nighttime darkness, I didn't notice any color shifting (and to clarify, I'm reviewing these on my calibrated BenQ monitor).

Two side notes to mention:

I now own several different items from K&F and I've been increasingly impressed with this brand of photography products. This filter is definitely going in the camera bag and I will be trying it out as often as possible.

Additionally, this filter is packaged in one of the nicest hard cases I've seen. The smoke gray circular case stands amount amongst a sea of white square cases for my other filters, and includes a really neat rubber "mount" inside to hold a variety of filter sizes without it flopping around in the case.

I have become a great fan of K&F filters. They are machined well and easily screw onto my lens and other filters. I have a small complaint, I use smaller 58mm filters on my primes and this filter comes in a large box. Makes it difficult to put in my pocket.

The shimmer filter adds a slight glow around highlights much like a fog filter, however it does not interfere with focus. As seen in my photo the filter adds a romantic glow. Seems like a good value for a quality filter.

This is review is for: K&F Concept 72mm Shimmer Diffusion Filter Optical Glass Glimmer Effect Filter for Camera Lens Nano-X Series
Purchase price: $54.99 USD

I wanted the 72mm Tiffen Glimmerglass® Filter, but not at $125. I saw this K&F filter that appeared to have the same functionality. Upon receipt, I compared it to the Glimmerglass 5 filter I do have, and the patterns are virtually identical. The filter diffuses harsh light sources and creates a soft, pleasing glow.

The filter fitment is good. It screws on smoothly, and comes off easily as well. The packaging was good, with a protective case that is easy to open and has a silicone insert that prevents the filter from moving.

For less than half the price of Glimmerglass, this K&F filter is a good alternative.

The price compared to other brands is great. I bought them as I film racing and wanted to protect my lenses and bring some halation to my sharp lenses. The I has a subtle effect that works well to bloom out the lights especially car headlights to make them easier on the eyes. The II is definitely more of a stylized look and softens the image a lot. A good example for it’s use case would be if you film a flashback scene in a narrative project.

There should be a trial piece before purchase. I love the quality. It didn’t help much to understand the image quality unless proper editing. I love the quality of K&F
