Does everything I expected it to.

bought the rectangular filter set directly from K&F. Since I have worked with screw filters in the past and had the problem with vignetting when screwing several filters on top of each other, I have wanted to buy a rectangular filter set for a long time. Since the sets from NISI, Haida and other well-known manufacturers are very, very expensive, as a hobby photographer I was looking for a cheaper alternative. When I saw several reviews on YouTube, I decided on the K&F set, which is half the price of Haida and CO. I have absolutely no regrets about my decision. The filter holder is very valuable and well thought out. I particularly like how the polarizing filter is attached to the holder and how it can be adjusted using the small wheel. The filters themselves are made of optical glass and show no color cast and are also well coated. Another positive aspect is that the filters have a plastic frame with a tab. This allows the filters to be inserted and removed without annoying fingerprints. A bag is included to store and transport the holder and the filters in it. Also included are various adapter rings for different filter thread diameters. As a landscape hobby photographer, I no longer want to do without the advantages over screw-on filters. I give a clear purchase recommendation for amateur photographers and professionals too! I wasn't expecting such excellent quality for this price. It's amazing what K&F delivers here.

I am very satisfied with the optical quality of this filter. Especially in comparison (e.g. with Cokin) stell

Scope of delivery: - filter holder for 100mm x 100mm filter - adapter ring 67mm - adapter ring 72mm - adapter ring 77mm - adapter ring 82mm - padded cardboard box for filter holder The set makes a very valuable impression overall. The adapter rings are made of black anodized aluminum - they are well made, not sharp-edged and the thread can be easily screwed onto lenses. Apart from the filter inserts, which are made of plastic, the filter holder is also made of black anodized aluminum. Here, too, the processing is excellent. Maybe the quality of the plastic inserts could be a tick better, but that's already whining at the highest level. The inserts fit all 100mm x 100mm filters with a thickness of 1mm - 2mm. packaging was impeccable; Adapters are individually wrapped; Filter holder is in a nice padded cardboard box. Full points and recommendation for a perfect rectangular filter system at a significantly lower price than some other manufacturers.

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

I've used the filter several times and it works great plus the mount works great and have already used other filters with it...

received the new X-PRO filter set today and have already tested its applicability in the apartment. I'll give you a verdict on the quality of the filter glasses and how they can be combined in one shot... The box supplied holds the holder + adapter rings + CPL + ND 8/64/1000. You can pull out the compartments on the drawstring and then remove the filters very easily. The plastic filter frames are discreetly sharp-edged, but not uncomfortable, and allow the filter to be removed and handled without having to touch the glass. Thanks to the tabs on the frame, the filters can also be pulled out of the holder very easily, especially in any order. I ordered two empty frames in 100 X 150 from the manufacturer's website, which are supposed to hold my graduated filters, which I have from another manufacturer, upon receipt. I'm curious how well this works. If it works, then I have a complete system for myself, with CPL, three ND filters and two graduated filters (Soft 0.9 and Reverse Soft 0.9). Sliding the filters in and out of the holder requires some force, but isn't awkward or imprecise. In this way, the graduated filter will also be easy to align. The handling of the CPL filter with the insert bracket is great, the turning mechanism is a bit rough, but precise. Screwing the adapter rings onto the lens works very well, the threads are cleanly worked, so nothing rubs. Attaching the holder to the adapter ring is also a joy and the presence of a set screw is very welcome as the holder rotates on the ring with relative ease. The handling of the system has already convinced me, I can live well with "only" two slots for my needs and I'm looking forward to the first use, in the next few days, in the great outdoors and with cold fingers. So far I've worked with round screw filters and dispensed with gradient filters, which I would like to change now. I also looked at the system from Rollei (Mark II), which cannot keep up with the handling of the X-PRO from K+F. Everything is very flat and fiddly, offers hardly any contact surface for holding and assembling the parts. Getting the polarizing filter or adapter ring out of the holder is no fun and almost impossible with cold fingers. K&F solved this much better. If you want to use gradient filters, the X-PRO set is a good choice. If you only need gray filters, I would recommend a magnetic round filter set with a diameter that is significantly larger than your largest lens, which is even faster to use, is more compact and should then do not darken with several filters in parallel.

Worth having it

First time using an ND filter and I’m really pleased with the photo I took. The quality is really good. Thank you!

Great ND with no color flair. Took photo vacation to Ireland.
