Square Filter Kit ND1000 + GND8 + Metal Square Filter Holder Set

A few years ago, I started beefing up my camera equipment. I had a Canon 5D Mark IV camera body, but didn’t have great glass. So, I started my gear journey by upgrading my lenses. I now have four amazing lenses including a 70-200, 24-70, 100mm Macro, and a Wide Angle lens. After I finalized my collection of lenses, I started looking at accessories I needed to accompany those lenses and came up with a short list of items that included high-quality filters. The problem I had was that I needed to be able have filters that works with all my lenses. Buying filters for each one of your lenses can get really cost prohibitive. So, one solution I found was to get a square filter with step-down rings. K&F Concept has a great option for this type of set-up so I gave it a try.

About a month ago, I shot photos at a wedding on a mountaintop in Tennessee. It was in the middle of the afternoon and the sun was super bright at the location of the ceremony. The venue was huge and I wanted to pack my camera bag somewhat light so that I didn’t have to struggle with tons of equipment. The square filter set from K&F concept was perfect for this type of work. The kit is lightweight and it makes it possible to use the one filter for several different sizes of lenses. During this wedding I was working with an 82mm lens and a 77mm lens as my primary glass. At the ceremony site, I had to quickly swap lenses and reapply the filter in order to get the shots the couple wanted. I found gaps in the ceremony where I could quietly and quickly change lenses and attach the filters without disturbing the event. It worked perfectly and even though some people might consider it cumbersome, I thought it was a lot easier than having to swap lenses and then screw filter into each lens.

When using these filters, I shot exclusively in RAW, but did not perceive any color cast from the filters. The mount is solid and the filter is well-protected by the soft lining in the case. It’s very easy to attach the mount to the lenses and in my opinion is actually easier to work with than individual filters.

I do feel like the lens adapter could fit a little more snuggly onto the camera lens, but I’m definitely not complaining about that and it is certainly not a dealbreaker. It’s just a tweak that could make the product even better than it already is.

One of the most appealing features of this product is its price. At £100, it’s much more budget-friendly than purchasing a single ND1000 filter. This is a great set-up for beginners and professionals alike.

DANGER!!! This review covers both the installation kit with the ND1000 filter and the GND8 soft filter that I bought together.

wanted a filter holder with these characteristics and an ND filter to start my Pinitos in long exposure photography. I chose this brand as I usually like what it offers (and quite tight especially for the price it offers) A sturdy metal filter holder with safety release to be placed on adapters and a filter ND 1000 that is perfect, to take such photos with light. Presentation and packaging with which they are delivered, the filter, as you can see in the photos, comes with a synthetic leather case 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 its case becomes. It's a filter holder for 100x100 and I think it's great, both in terms of quality and price, to start with this type of photo without having to invest too much. I know that for the picture to be good you need to invest in crystals of this type to get a sharp picture, but unless you're sure you want to spend that much (like me, that's a whim, it to try) seems the best to me.

Absolutely delighted! K&F did a lot of things right here! When I unpacked the adapter rings and the holder, I was already very satisfied. Metal case from 48 to 82 rings. But then the glass, it is packed in a leather case, very high quality! This is otherwise only known from very large brands and companies, which can also be paid well for expensive money, but the price is right here! Only the German translation in the instructions leaves something to be desired! Doesn't flow into my rating! I can overlook that! Dear K&F team, please keep it up! An absolutely overwhelmed customer that you won with me!

Great. Good quality and highly recommended

I thought long and hard about getting this filter. Ultimately, however, you have no risk with Amazon and can test them. Pro: Top packed. Glass filter that is evenly coated. leather pouch. I find the bag better than the bulky boxes such. B from Lee or Haida Negative: Slight but really very slight color changes at the edge. I'll get the other filters to test. #JAMPHOTO

I am a passionate landscape photographer as a hobby and have now switched from the screw filters to this rectangular filter system from K&F. The screw-in filters were all fine, but you don't have the option of attaching a graduated filter to the ND filter in order to achieve even nicer effects.
It is mounted on the lens using so-called adapter rings, which are included in the most common sizes for lenses.
After attaching the adapter ring to the lens, the filter holder is attached. This is secured by a small lever (spring-loaded) and later released again with this.
Now you can slide the filter plates into the filter holder. This lifts a bit severely but it should also hold and must not wobble.
It is also important to observe that the filter used is close to the lens so that no more light can penetrate between the filter and the lens, which could possibly ruin the recordings.
In terms of quality, the system makes a good impression considering the price. The only thing I noticed negatively is that the filter holder has some play after it is placed on the adapter ring and why there is no adapter ring for a 55mm filter diameter in the set, I also ask. 55mm is a common diameter for lenses.

I can highly recommend the K&F system for amateur photographers. The professionals will probably use filter holder systems from other manufacturers, but they also cost a lot more.

The adapter rings allow us to place the filter holder on any lens as we have a large number of different diameters. They are made of black metal and are well made. Labeled on each ring with the appropriate diameter. The filter holder is metallic with the part where the filters go made of some kind of hard plastic. Two 100x100 filters and 100x150mm gradients fit easily. The system of attachment to the adapter ring is via a very manageable metal tab. In several tests that I carried out under different lighting conditions, I did not notice the entry of residual light through the space between the filter and the filter holder. The photos have a slight magenta tint which is very easy to correct when editing, but it's not exaggerated at all. I am very happy and enjoying it very much. I recommend it!

This is the first thing I have and I'm happy

The filter pack is well made and designed to be protected. The filter removal system is practical, pleasant to use and useful for controlling the high-pitched sounds of the sky, etc. In my opinion, it will be very important to choose a metal filter holder that precisely blocks the mounted filters.
