there is a 50mm 1.8 e mount with os pa. if more on portraits bro cia, get the 50 nalang and when budget allows get the 16 mil pud. most of my photos are taken with the 16 mil. ok raman pud, lingaw rasad na lens. wa na gyud nako ma gamit ang 18-55mil. like edwin said you can use your nikkor lenses on the nex. if you have G lenses, just get a nikon to nex adapter that comes with an aperture control
gl bro!
