K&F XV37 82mm Fader ND Filter Neutral Density Variable Filter ND2 to ND32
Received item tested it, but will not keep it
I received this product and was excited to tested on a GMaster lens. Unfortunately, the image coming out were not what I was expecting to see.1-) Lost of image quality. I did a couple of shots with and without the lens filter and results always show the image without the filter to be clear.2-) In between the two glass of the filter there seem to be some sort of liquid. Maybe reason why the image do not look clear. It appear to be oil applied to the rotation of the rings2- Quality, the product looks and feels decently made. But, do not expect similar quality of the other higher brands. I am sure K&F will improve their line of filter in the future.3-) Stops, the filter have a a rotation mechanism which prevent the rings move further the lower or higher stops. Which also void the X mark. Corner to corner look pretty good.Overall, is a good filter for those who are looking to protect their lens from the elements. For professional use there need to be some improvements.
