Use of each of my Nikon lenses (at a D700 full frame) one of these filters. Those things are slim in design, so you do not even have to make the wide angle at maximum aperture over shadowing the filter concerns, especially something makes the full-frame sensor already rather striking times. I must never use more than a bellows through the nonexistent dust affinity to remove the speck of dust that off to show themselves and. The optical quality appears to be like the color fidelity without blemish, of course, does not seem a hindrance, depending on condition advantages, for images in the middle of the night from the moon hand in daylight, the light intensity of my lenses has not suffered. The scratch protection, I'll never have to try with all due respect, but in reality we assemble precisely why these things and not because they about sooo look good. Version = very solid metal, screwed his fill and wobble-free. Quality above all I would say unassailable and well. Price really affordable, fast delivery. Conclusion: A clear recommendation.
