K&F Concept 67mm Split Diopter Prism Filter, Linear Prism Effect Filter, K9 Optical Glass, Blurred Refraction, Close-up Effect.

This is a K&F Concept filter (67mm model) with a Split Diopter Prism effect, with two semicircular glass lenses facing each other, leaving a central linear zone without correction glass. Therefore, if an AF zone is set, the filter will not be able to be adjusted. central or an optimal manual focus in this central area, the contours of that central line of the focused image remain in blur and with some whitish halo diffusion depending on the incidence of light, as the outer ring of the filter is adjustable, it is free to rotate on its other support ring to fix it to the filter holder, so we can orient the blur up + down, right + left, even diagonally, so that it is much better understood and even more visible the effect of this filter instead of in photography mode, I have made several videos edited into one with several frames so that you can clearly appreciate the effects that can be achieved with it (I hope you know how to appreciate the effort to show it) and you can see how to use it in your artistic shots, either in photography or video mode. In addition to the protective box, as you will see, a set of 3 small individual cleaning cloths of the same brand is sent; (Cleaning this type of filter is a bit more difficult; try to avoid its center groove.)

My rating for this effects filter and cleaning cloth kit is:
"5 STARS" = [ * * * * * ]. I hope you find this review helpful. Best regards.
