A:Answer It could be used on mirrorless cameras however, it drops your megapixels, therefore the quality of the image is not as rich as expected from mirrorless. Example; the Nikon z6 is a 24.5 megapixel beast of a camera, that lens would make it a 10 megapixel, therefore reducing image quality. If you intend on printing images larger than an 8x10, I suspect pixalation with larger images would be a problem.
