K&F Concept SN25T ND1000 Square Filter 100x100mm + Metal Holder + 8pcs Adapter Rings For DSLR

It’s actually not too bad for this price. Everything works fine but it’s a bit loose. I have to put some tissues in between to make it tight

Really good filters. For the money and got quality

 Been looking for a filter that I could do long exposure with water scenery to capture the silky look. Because of the lock down I haven't been able to fully test it but from some fountain picture I took in my backyard the quality is amazing. When ever the beaches reopen where i'm at ill update the photos I have.What I really like about the kit is that they provide you with so many lens adapter. I have Nikon lens and trying to transition myself into the Sony size so having that option is fantastic. For example I have a Nikon 50mm lens that takes a 58mm ring. My Sony 50mm takes a 49mm ring. This kit provides that to you and so you don't have to buy multiple filter for different lens. Whats great about the kit is that you can easily remove and install the filter with the quick disconnect so after you focus at what ever you want just reinstall the filter with a snap.The rings seems to be made of high quality aluminum and the finish is flawless, sames goes with the adapter plate. the Glass itself is simply amazing. For the price you cant beat it just starting out in photography. K&F photography line has improved so much over the years.My only complaint is that the filter doesn't sit flush against the filter housing there is a slight gap very small, though it hasn't had any issue with it and not sure it will unless the sun hits it in the right spot I guess. Overall i'm very happy with the purchasePros:• Variety of lens adapter• High quality glass• Quick disconnect for removing and installing the filter on the camera• Well packagedCons:• The filter doesn't sit flush against the adapter letting light inIf you found this review helpful please hit the helpful button, it lets me know my review might have helped you out.

This is the second one I have bought. Both have been great! And the customer service was excellent!

Came really well packaged and a great value. Filter seems good, no noticeable hues, adapter rings for most size lenses and the metal holder seem durable

Not terrible but you do notice a little bit of degradation in image quality. However for the price it's fantastic.

I have been looking for different ND filters before made a decision to buy this one. After several shots, it seems perfect for me as the following reasons:1. I got 2 different prime lens (and one more new is coming) with different diameters, so this square filter can applicable for all. It seems a quite economic solution. With a low budget, it seems a better deal than buying separately circular filters.2. The set includes all kind of diameters and easy to set up with typically clip and adapters. That is really helpful when focusing. It saves a lot of time than working with circular filters.3. The optical quality is great, especially at the corners. The pictures are clear and shaped.In conclusion, I believe that is a great deal for beginners and professional as well.

Although I'm an avid photographer, and have used several different types of filters, this was my first time experimenting with a square filter like this one. The quality of the glass seems high, with no noticeable distortion, and the filter holder keeps the glass close enough to the lens that there weren't any strange reflections or flares visible. The photograph I've posted was taken using the ND1000 filter in bright daylight at ISO 100, f/2.8, and 1/4 second. This is a very dark ND filter, and will block a lot of light. I do notice vignetting at the outside corners of the image, but this is likely due to my lens (Olympus 12-40mm Pro f/2.8) rather than the ND filter itself as the darker image would naturally draw out those flaws in the lens that diminish with brighter exposures, and the consistency of the vignetting is congruent with a circular lens element rather than with a square filter.Here's what I liked and didn't like:Positive:1. The filter itself is of high quality glass with no noticeable defects or inconsistencies2. The adapter rings provide a wide range of lenses to be attached3. The mounting system allows for two filters to be mounted simultaneously4. The mounting system can be quickly attached and removed with the press of a button5. Filters slide in and out easily, but fit securely in the mounting system6. The case for the ND filter and the overall packaging is nice7. The ND filter is clearly labeled on one edge so you know what filter you're working with8. The instructions are clear and helpfulCons:1. The mounting system doesn't always clip on easily. This may just be something I need to get used to, but I wish there was a clearer *CLICK* when it locks in place2. The mounting system is secure, but it is released completely with the press of a button. While convenient, this could lead to an accidental release of the mounting system and whatever filter you have attached. In my case, I accidentally bumped the release button, dropping my ND filter onto pavement where it shattered. Some sort of sliding lock in addition to the button would be idealPreferences (These are things that I don't prefer, but that may be a better or worse fit for you):1. The mounting system spins freely on the front of the camera. This may be helpful for some people, but I would prefer that it was fixed, or at least allowed me to set it to fixed and then unlock it to rotate2. There are no mounting points for an eyebrow, barn doors, hood etc. These aren't essential in every situation, but you would need an additional matte box in some situations. Making these accessories available would be a great upgrade

The pack looks premium, the glass is high quality. Love it for less than $100.

Simple to swap out filters as well as adapt to a wide range of lens diameters.
