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.

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

Hi I’m Sam Christie 80Years old had a triple bypass and I’ve now got lung cancer. I’m new to photography, struggling but having FUN AND ITS FANTASTIC. Thanks K&F.

I decided on this filter because it is easy to attach and detach from the lens, is thin at the front and rear, and includes a CPL filter
The CPL filter is simply dropped in from the top after opening the lid. If the front and back are wrong, it will not fit.
The rectangular filter has the right amount of friction and doesn't feel like it's falling off.
Almost all metal, but excluding the four metal adaptor rings and the CPL filter, the holder alone weighs 110g.
Design-wise, the overall impression is one of refinement.
The only drawback is that when I tried to mount it on my Canon RF85mm F1.2 L USM with 82mm filter frame, the orange knob that locks the adapter ring interferes with the thick housing of the lens and does not fit (if the knob was a bit more on the outside...). I solved this problem by inserting the 82-77mm step-down ring and 77-82mm step-up ring from the camera side and moving this holder itself forward by about 8mm. When a rectangular filter is mounted, there is no vignetting. If you are worried about vignetting, you can use the 82-86mm step-up ring and 86-82mm step-down ring.

Good Product and reliable one

Since I haven't worked with ND filters before, I don't know what I could complain about here.
Overall I am very satisfied with the glasses from K&F. You get a high-quality, processed filter with top optical quality and a good scope of delivery (artificial leather case).

I wanted a filter holder with these characteristics and an ND filter to start my first steps in long exposure photography. I chose this brand as I usually like what it offers (and quite adapted especially for the price it offers) A sturdy metal filter holder with safety trigger to put on the adapters and an ND 1000 filter that fits perfectly is to start with this type of photos even with light see in the photos, it comes with a faux leather cover with a soft velvety interior so that the glass and the filter holder do not suffer any damage, although it is presented in the box without a cover.

This is ideal for my photography as I only need one set of filters to fit all my lenses.

It's made out of really high quality leather and has a magnet to keep it closed. There's a belt loop that I'll probably never use, but there's a metal frame for clipping onto your bag that I'll probably use.

I don't see any appreciable color cast. So if you want to experiment with proper filters without breaking the bank these are a good buy. The filter cases are beautiful and the overall product presentation/packaging exudes quality.
