I've been taking photos as a hobby for several decades, first analogue, then of course almost exclusively digital for 15 years, i.e. I've seen and tried out a number of photo accessories over the years. With the filter I bought here, three things were decisive. 1. The quality, I've spent too much money unnecessarily on useless photo accessories 2. The price, I don't see an point in spending more money which you don't see in the photos afterwards anyway 3. The durability and expansion of a plug-in filter system Attached Image with the graduated gray filter All points speak for this product. The filters are quickly attached, make a stable impression and are supplied in a practical case. The plug-in filter system is more than useful for the hobby photographer. In any case, I wouldn't want to be without it in my photo bag. I can't understand the fact that the filters are difficult to insert, which is often criticized here, on the contrary I even find this important because otherwise the filter could quickly fall through. After more than half a year and several sessions, I can only say about the durability of the filters, so far nothing has been scratched or even broken. Conclusion: Anyone who takes pictures knows that this hobby can sometimes cost a lot of money, and often with this hobby it really is so; "If you buy cheap, you buy twice". However, I don't have the impression with this product that the more expensive competitors, who also offer plug-in filter systems, do it so much better that the surcharge would be worth it here. That's why I can only recommend this system

the quality of these filters seems to be on par with others (more expensive ones). The course is clean and evenly straight. The very well thought-out pockets, with their pull-out tab, offer fingerprint-free handling. Clear purchase recommendation on my part...!!!

A mild light reducer. Can be easily plugged in together with other medium-strength ND filters. Quality like other manufacturers offer. Good optical glass.

I informed them of these issues even though they were purchases made 18 months ago. They have since sent me a completely new holder with the missing part attached.

Excellent service. It's still worth checking when it arrives in case something else slipped through the cracks during production.

Gap between glass filter and filter holder. Not ideal if the purpose of an ND filter is to reduce the light entering the lens. Needs some work.

Well presented lookswell made pouch is nice touch oasis, t tried it yet for color casting but for the price I don't expect Lee quality give one a try

As the title suggests... Great metal filter holder. Excellent packaging, K&f, proves that it is a company that paints materials of excellent quality, no longer an alternative to the most famous filters, but first class! Recommended

The gray filter comes in a sturdy protective case and fits exactly into my Rollei rectangular filter holder. The optical properties do not reveal any errors. A satisfied customer thanks you.

Something to complain about almost always, but in relation to the price offered, everything is really fine! Filters are good. I haven't had any discoloration yet. The insertion is a little heavy, but the glasses will keep it safe. Have nothing to complain about - fits.

I'm positively surprised. Nice that there is such quality at a fair price. The colour deviation is minor and can be easily adjusted in LR, PS or any other program. The handling is very simple, no fumbling action is necessary, which is particularly advantageous in the terrain. I prefer this type of filter especially in bad, humid weather. Unlike screw filters, no moisture can accumulate between lens and filter.

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