A high-quality brand is not only characterized by the quality of its products, but also by the range of variations that are offered. Especially in the photo market there's great competition, a large number of different companies are trying to sell their range of camera bodies, lenses, etc. Often it's not easy to find accessories for models other than the bestsellers - but not with NiSi. The filter manufacturer responds to almost every need we photographers can imagine; there is hardly a lens where the suitable filter holder doesn't exist. When I bought my new Samyang XP 14mm f / 2.4 ultra-wideangle lens a while ago, I knew that I could rely on NiSi, because even for this rather rare lens there exists an available solution already: the 150mm "Classic" filter holder from the Q-series.
How does the Q150 work? - Handling
The filter holder for my Samyang 14mm can be easily attached to the front of the lens using a rotatable lock. Due to the construction of this lens, there is a slight vignetting, which cannot be avoided with an ultra-wide angle and can also be reduced by correcting the lens distortion. The surface of the Q150 is coated in matt black to minimize unwanted reflections. In addition, it can be rotated flexibly in any direction, which makes aligning the filters very easy. It weighs 250 grams and can be easily stowed in any photo backpack.
The slight vignetting in the corners of the image is visible, but can easily be corrected in post-processing.

Conclusion
I have tested the Q150mm system and the two filters in the French Alps and my home in Bavaria. Given the usual high NiSi quality, I am not surprised when it comes to their performance. The system is robust and easy to use, which makes working with it in nature a pleasure. Although I had to get used to the handling, as the filters are a bit larger than my V6 100mm system, the changeover does not cause any difficulties. The already mentioned vignetting can be seen clearly at the corners of the pictures, but is easy to fix. I noticed a minimal green cast with the GND graduated filter, which I was able to correct just as quickly in raw editing. Overall, I am very happy to be able to use NiSi filters for my ultra wideangle lens as well!
