>>3659324the fujian/fotasy lens wont mount on the nikon dslr due to the flange distance. that lens has a very swirlish background blur at 1.7 aperture tho. if you want the cheapest lens with AF for portraiture get the 50 1.8G for apsc (the lens with internal motor) but it has a diff. bokeh compared to the cctv lens. using the 50 in tight spaces for portraiture can be tricky tho. but I would probably get a 35 1.8G as a more flexible option but with lesser background blur for portraiture and general use and can be substitute for the kit lens, a bit more expensive tho. check your kit lens and play with both 35 and 50 focal lengths exclusively and see what fits you.
