Effects of changing hue, color saturation and luminous attenuation with sunlight in landscapes.
This is a REVIEW REVIEW for the item sold on kf congcept with description:
K&F Concept Nano-K Magnetic Filter, CPL Circular Polarizing Filter with Nano Coating for 77mm Objective (Includes Cleaning Cloth).
This is a CPL filter (polarized light control by rotation on its axis) that is very convenient to use thanks to its two-piece threaded anchor ring and filter with magnetic outer ring, the threaded ring is installed and then it can be removed with a simple grip and pull of its contour (which has a ribbed texture for a better grip) and to fix it again, then present it to the ring and position it until you notice the magnetic pull and its anchor in a well-aligned position.
In terms of performance, they are noticeable outdoors with good solar lighting (indoors and artificial light is not noticeable) and very shaded outdoors, so it is usually useful when shooting landscapes, especially in which an area of sky or clouds appears or where there is a reflection of light in rivers, springs, lakes, etc... or with reflections of a metallic effect. Depending on the orientation in which the ring is rotated, the image darkens or lightens a little, attenuating the sunlight and taking on greater or lower color saturation (when rotated on the magnetic system it makes a little sound like a rubbing squeak, but as is normally used in photography and video, the position is first searched and then the recording is activated, since it does not affect the audio of the recordings.
I made an edited video with some image changes on the same shots, only partially rotating the CPL polarizing ring. The images appear with a higher color tone but less luminous, which is why it is advisable to adjust the exposure meter gain a little, since when we rotate the ring if we are in manual mode with reference to it or in the preferred aperture or speed control modes, the shooting speeds or the diaphragm apertures vary respectively, and I personally like images that are a little more vivid, both the colors and the brightness, but without annoying reflections.
Due to its very good price/quality ratio and its ease of installation and exchange with filters from the same “Magnetic adapter ring” magnetic attachment ring system, its thin “Slim” support that prevents vignetting on angular lenses, its good presentation in a protective box and the special cleaning cloth included in the set my rating for this K&F concept filter is:
"5 STARS" = [* * * * * *]. I hope you find this review useful, Regards.
The drawback that I forgot to review and noticed later is that on CANON lenses with the front covers of the EF range, they are not attached either with the filter installed or with the filter ring with the filter removed, since the filter is a narrow format (SLIM), the support tabs of the front cover of the lens do not engage the profile of either the filter or its support ring, so to be able to put the cover on, you must also remove the threaded ring and store the set in its box.
