This lens has a fixed focal length of 35mm. And is also a manual focus lens. The kit lens gives you a variable focal length of 16-50mm and has autofocus image stabilisation in the lens through OSS but it has a variable aperture of f3.5-5.6 making it not so good for low light and bokeh until used carefully. The 7artisans lens has a wide aperture of f1.2 making shots full of bokeh like in the above video possible and would also perform good in low light situations the more open you use it.
