With modern cameras, the use of a UV filter is actually no longer necessary. I therefore use the UV filter more to protect the front lens against scratches and dirt. I did not observe a frequently reported reduction in image quality (when using filters), so protecting the expensive lens is more important to me.

I could not detect any color differences thanks to the multiple coating. However, I could not observe any gain in contrast and sharpness, but this is more due to the good coating of my lens and the use on a modern DSLM. This will probably be different on an "old" analog camera. Unfortunately, I was unable to test this because I do not have a lens with a suitable filter diameter.

The filter can also be used on stronger wide-angle lenses thanks to its slim brass mount. I use the filter with a 24-70mm lens on full format. Due to the design, the minimum focal length should be around 17mm on full format. The mount is cleanly processed and fits well into the thread on the lens.

The filter comes well packaged in a sturdy leather bag. Once you have removed the filter and bag, the outer packaging can also be used as a picture frame. The delivery includes a stand and an additional cleaning cloth for the filter. Everything looks very high-quality and expensive.
