Nice filter for the price. I need to play around with it more, but had a ton of fun using it.

The filter is heavier than expected. Good weight and solid glass

Really cool filter for getting a little variety to your shots, t a really nice price!
Optics are clean and clear and the effect looks really cool when done right.
Threads are clean and smooth as well, and comes off the lens like it should.
It's not something that I'll use every shoot, but it's great for adding a little extra uniqueness to your shots.

I normally stay far away from weird filters that produce strange effects, mists or grades. But I'd not seen one of these before and thought I'd give it a go. I'm glad I did.

I thought it would be some kind of gimmicky plastic filter but on unpacking, was surprised to find it made of glass and metal. This is a hefty filter! Once screwed in place, it rotates easily for the kaleidoscope effect you want.

This is a niche filter that isn't for everyday use, but I have to say it's got my imagination going. I do a lot of light streak/long shutter night light photography, and gave it a try on a locked off camera and lens to capture cars passing at night. The resulting photos are insane. Very abstract and visually appealing (no, I'm not going to show you so you'll nick the idea!), I'll get a lot more use out of this than I thought. I'm sure other pro photographers will laugh at the sight of such a filter, but don't knock it until you try it! I'm very happy with the shots it's given me.

K&F usually comes through with great products, and this filter is more of the same.
The lens has a lot of glass and heft in the hand.
I was more than satisfied with center sharpness, but just realize the farther away you shoot...there are limitations. This would be for portrait work and even macro...both still and video. I put this filter on my Sony 135mm f/1.8 GM with the Sony A7RIV...center was very sharp.

This is a fun filter to use, and for the money...a great value.
Images look solid as does video...as long as you keep the distance down.
Comes with a nice case and some cleaning cloths...for that hefty chunk of quality glass.

This filter creates and interesting effect that is good for specific shots. I don't see myself using this a lot but, I would say this is the best kaleidoscope filter I have come across. The lens itself is made of quality materials that I have come to know from all the K&F filters I own. Fits my 82mm G-Master perfectly. Comes in a great protective case. I highly recommend this lens.

This is one of those special effects filters you can add to make ordinary pictures stand out a bit without the need for post-processing software (maintains picture integrity). This screws onto the lens and then you take the pic. Works with the auto-focus on my Nikon D3200 with no issues. Do note that because of the effect, light can get diffused a bit and colors *may* not be as sharp. Still, this is quite fun and another lens I can use to keep photography fun.

It gives a different look. I love the circular repetition effect that the filter gives at a distance of 5 to 15 feet. The look stands out very well. The distance will depend on the size of the object to be focused on. I used it for faces and flowers and it was very good

As a full time filmmaker I own several K&F Concepts products and they always deliver quality. This filter is no different. Great glass and the packing is top notch.
