Meeting expectation

I got mine yesterday and said I would test out the performance with and without this filter, I have a vintage Minolta lens which was my grandad's so it is quite precious to me and I wanted to keep it from getting damaged, As the title says there is slight yellowing, vignette and a barely noticeable loss in sharpness that I can notice while looking at it on my computer screen, although the compressed pictures I have added may not show the full resolution of the original images. Let's break down what I have found: The yellowing - There is a slight yellow tint to this filter which makes sense, it's a UV filter so the shorter wavelength light may have some trouble getting through, This is no issue to me as it can easily be tweaked and fixed in software after to add a little extra blue, or this might give you better results in the field depending on your conditions The vignette - This is ever so slight but noticeable when looking at the same picture with the filter on and off, this again is no problem to me as it can be fixed or tweaked in software so that it is indistinguishable The loss in sharpness - The loss in sharpness is barely noticeable even at 400% which is great, simply adding 1 percent more sharpening afterward makes this a complete non-issue for me. You have to be looking at the photo at 200% or above to notice any kind of loss and even at that, you will have to look hard. For what I paid for this filter I am happy knowing that it is not degrading my image in any meaningful way and that it will act as a shield and protect my glass from scratches and dust, I will be adding more of these for my lenses and will not be compelled to remove the filter to take a photo as I would be with others, Great product, Highly Recommend!

I have attached this filter at the front of 20x80 Binoculars they gave me a warm color and removed Chromatic Abberations to 80%. The glass is clear and have high transmission of light. I will try more of their filters. 😎 I have purchased alot of different products from this brand and always got amazed by the premium packaging and quality of products.

Have more coating, good quality, but if you have a variable nd filter then it's a waste of money.

Excelente desempeño. No pereciera interferir con la claridad y nitidez de las imágenes captadas por mi objetivo. Muy recomendable.

Passt perfekt und tut was es soll. Es ist primär ein Schutz für die Objektivlinsen. Ob es UV-Strahlen zuverlässig filtert, konnte ich nicht feststellen.
